Record the data for each case and ⦠Collect Materials 2. answer choices 27 m/s. The ball will hit the ⦠Use an if you need to show that the car is moving. C. Angular Momentum Toys Our results may have been attributed mostly to the fact that heavier objects are more resistant to air resistance. Place the two motion gates at the end of the ramp directly one after the other. My variables are height, time for bounces, mass of ball, bouncing surface and number of bounces. Solution for The potential energy of a 40-kg cannon ball is 14000J. The ball's acceleration gets closer to the acceleration of gravity as the slope gets more and more steep. INTRODUCTION In this laboratory Iâm going to relate the time that a ball needs for 6 bounces from different dropping heights. ii. In lab this week, we will create and analyze cases of static equilibrium like in the sample problem to the right. The momentum of the one marble rolling down the ramp before the collision should be equal to the sum of the momentums of the marbles after the collision. Mr. S. sets up an experiment to see how the mass of a ball affects the distance it rolls off a ramp. Prior to this week's lab be sure to 1) Watch the two videos to the right, 2) Watch my Pre Lab video below, 3) Explore the simulation as described in the video, and 4) Complete the pre-lab quiz on Blackboard. 8. In the ramp lab, one of the ramps had a slight bow to it and the data collected took an odd shaped curve unlike the data collected by other groups. d) Zero the force probe. Explain your answer. Place the marble on the table. Measure the distance between the centres of both of the motion gates and record the number. After the train coasts to the conclusion of the track, the energy reservoir is all but empty. Pull the cart parallel to the ramp (!!). 1. Ask the instructor or the lab assistant to show you how to enter this number in the computer. But what force? Always? To make measurements use LoggerPro and the same video analysis procedure used in Experiment 6 in the lab manual. Pull the cart at an angle of 60o to the surface of the ramp (!!). Newtonâs First Law of Motion tells us the ball would travel in a straight line forever unless a force acts on the ball. Let the ball start rolling from 0 cm. We will write the moment of inertia in a ⦠The independent variable is the dropping height H because I ⦠Ramp Ramp Floor Floor Draw a on the picture below, where it would have the most kinetic energy. 3. When the marble is at rest what happens? The marble coming into the collision is called the "inbound" marble in this laboratory. 53 m/s. 2) Record the mass of each ball bearing below. 7. 4. The sphere The ring The disk Three-way tie Can't tell - it depends on mass and/or radius. Blow through the straw directing air at the marble. What is the acceleration of a ball rolling down a ramp that travels 1.2 m in 2 s? This means that after two seconds it would be moving at four meters per second, after three seconds at six meters per second and so on until it hits the end of the ramp. e) Find the force needed to pull the cart up the ramp at a constant velocity for the following cases: i. So a force must be acting on the ball. Unformatted text preview: Experiment 1 Distance Traveled by a Projectile In this experiment you will use kinematic equations to predict the range of a projectile set in motion To do this you will roll marbles down a ramp and off a table to observe vertical and horizontal motion Materials Sheet of Carbon Paper 1 Fishing Sinker Masking Tape 1 Marble Monofilament Line 1 Protractor 1 Ramp ⦠Question 1 Phenomena Test 1: Size of ball a) Prediction: If we roll two different sized balls down the inclined plane at the same time, marks on the incline. This ball has kinetic energy as it falls. 61 m/s The questions refer to a ball starting at rest and falling, or rolling down a straight ramp as shown. 2. Did the group using that ramp take bad or good data? Identify the INDEPENDENT variable. The limit for the balls acceleration is the acceleration of ⦠The ball used in this lab is large enough and light enough that air resistance may affect the acceleration in a small way. 4) Start with the ping pong ball. % Eff. ⢠measure h, H, s, and s1. Record how high EACH ball bounces when you do this. All pulls or pushes are called forces. Try blowing the marble at different angles. Then vx = 20 m sâ1 * challenge questions and vy = 0 + (9.8 m sâ2) (1.0 s) = 9.8 m sâ1 The speed of the ball at 1.0 s is given by: [ (20 m sâ1)2 + (9.8 m sâ1)2] ½ = 22.3 m sâ1 Q2. decrease. Choices on the left. 45 m/s. Why? Rotational Motion and Ramp Lab_web.pptx 0.04 m/s. This ball has potential energy because of its height. the edge of the track. This lab showed us how distance and time is present as a ball is rolling down an inclined ramp. 5) When the ball reaches the 20 cm. I learned that if you were to increase the distance and make the incline of the ramp steeper, the velocity of the ball would be highly affected- in the sense that it would increase. If the ball reaches the end of the ramp more than 0.2 s after 5.0 s, increase the angle between the floor and the ramp. Use a vernier caliper and measure the diameter of the ball. From this measurement (and its uncertainty), determine the k factor of the ball (and the uncertainty on k). 4. Lab 2 â Blowing Marble Materials: 1 straw, 1 golf ball, 1 marble Procedure: 1. Ignore friction and air resistance. In this case, the ramp angle is the independent variable (the one you can change) while 4. 3) Record the time it takes the objects to roll the entire length of the ramp - from âStartâ to âFinish (2.7 meters). How high was the cannon ball to have this much potential energy? The green vector arrow represents the velocity. 6. Questions to Ponder and Answer 1. Ball And Ramp Lab Answers 1/20 Downloaded from oos.mylearning.gemseducation.com on February 15, 2021 by guest Kindle File Format Ball And Ramp Lab Answers This is likewise one of the factors by obtaining the soft documents of this ball and ramp lab answers by online. You will need to have one person observe the larger ball and one person observe the smaller ball. How closely does the slope correspond to the acceleration? 5) Determine the velocity of the object. - Ball bearing - Ramp - Electrical tape - Carbon Paper Procedure: 1. If you tilt the ramp at a certain angle and roll the ball down the ramp, the ball will roll at a certain speed. 2. Place ramp upright on the desk. Take note of where the launched ball lands on the floor, and tape a sheet of white paper in that spot. 1. Set Notice how it continues to change in magnitude and eventually direction, starting from full length, going up the ramp to zero length, and then pointing down the ramp and ⦠Let us assume, for argumentâs sake, that the ramp is at a convenient slope such that, after rolling down it for one second, the ball is moving at two meters per second. of 6 bounces of a super-ball. This is an important quantity since the computer uses it to calculate the launch velocity of the ball. Release a ball near the bottom of the ramp so it strikes the magnet slowly and causes the Gauss Gun to fire. There should already be 20 cm. Getting to the Core Grade 8 Unit of Study STUDENT RESOURCE Roller from potential and kinetic energy roller coaster worksheet , source:docplayer.net. The lab uses a golf ball and ping pong ball, however other items can be substituted based on ⦠A video of the motion of the ball is provided for you on eclass or my website. Q1. stop your timer. You can roll a ball down a ramp, and it will pick up enough speed to âloop the loop.â Determine experimentally the minimum height h such that the ball loops the loop without leaving the track. Answer: 6.28 or 2Ï ... transfer of PE to KE of a golf ball rolling down a ramp. V = distance/time If the ramp is vertical, the ball just drops with acceleration due to gravity. Step 15: One student should mark the position of the ball on the ramp while the If the ball has a range of 110m, calculate the horizontal velocity of the tennis ball. stay the ⦠Launch the cart with the same ramp angle and initial velocity that you've been using throughout the lab. 1. Let the ball roll off the incline. As the angle of the ramp increases the acceleration of the ball increases. The pull of gravity between the Earth and the ball causes the ball to drop. I'd say I was successful. Let's say you have a ramp and a ball. Department of Physics and Astronomy | University of Mississippi 4) Repeat for a total of 3 trials for each object. Neglect air resistance and spin on the ball. You ⦠If it is lifted higher, it will have more potential energy. To observe a more significant affect from air resistance, repeat the ball tossing experiment three times, this time using a beach ball or other very light, large ball. A tennis ball is shot horizontally from a cannon at a height of 5.0m. decrease the angle between the floor and the ramp. The acceleration is .22823m/s/s, and the slope of the velocity graph is ⦠The correct answer is A, because the person's initial momentum is positive, the medicine ball gives a positive impulse to the person, so there's about one bar of impulse added to the system. Use Newtonâs Laws of Motion to explain what happens. Launch the ball from a certain height on the ramp. 3. 5. In doing this lab, I hoped to learn the position, velocity, and acceleration of a gently pushed cart on a ramp. A ramp- This can be made using items on hand at the time, for example you could create one by stacking books A heavy ball and light ball- For the lab two balls with different weights will be rolled down a ramp. Then place a sheet of carbon paper (ink side down) on the paper where the ball will land. Thus, at the end, there are 3 bars of momentum in total for the person (system). ⢠measure mass and radius of the ball. roll down an inclined plane faster than lighter rolling objects. Data: 1. How long would the golf ball be in the air if we had used a ramp where the inclined part was twice as long? Make sure ramps are secured firmly in place for each trial. PROJECTILE MOTION e The ball will strike the ground 1.0 s after it is PRACTICE QUESTIONS (WITH ANSWERS) struck. Sketch your setup in your lab book with the dimensions labeled. If you make the angle of the ramp steeper, the ball will roll faster. The answer, of course, is gravity. Repeat with the golf ball. If the ramp is horizontal, then the ball does not accelerate, as gravity pushes the ball into the ramp and not along the surface of the ramp. Start your timer. 5. Projectile Motions Lab Conducting the Lab Our lab was conducted by letting steel balls go at the top of the ramp, which basically is almost zero velocity at the top of the ramp. Choose one of the following questions and write your answer using complete ⦠If you allow the ball to travel for twice as much time (or distance), its velocity will. 1) You will need 5 ball bearings of different sizes. Acceleration is equivalent to the slope of velocity. You will record the time it takes the ball to roll down the incline every 20 cm. Try to keep the smaller ball in contact with the larger one. From the ramps top we count down and release, which at the same time we start counting time and stop at the time when I hear the ball hit the floor. c) Setup the ramp, cart, force probe as seen below in the figure.
