Marble Rolling Down A Ramp Experiment

Finally you push a marble on a ramp that represents the middle state between the first two in other words a ramp that is perfectly horizontal.

Marble rolling down a ramp experiment. Find more round objects spheres or cylinders that you can roll down the ramp. The marble speeds up on its way down the ramp. Use 1 d kinematics to predict the velocity of the ball xi at the bottom of the ramp. Set up the ramp with h 0 10 m above the table as shown in figure 1 2.

It slows down as it goes up. So that marble teetering at the top of the ramp has the potential energy of gravity which is the force that will pull it down the ramp. Taten williams luke kelly and jack ambrose. It starts to roll faster and faster down the ramp right.

After many trials he observed that the amount of time it took for the ball to roll down the entire length of the ramp was equal to double the amount of time it took for the same ball to only roll a quarter of the distance. But if you did this same experiment on a flat surface the marble would barely move right it is gravity that is pulling the ball down the ramp. I predict that the steeper the ramp the faster the marble will travel. In this experiment you will roll a marble down a ramp to find out.

Now you give a gentle push to the marble going uphill on the second ramp. Starting with the cylinder at rest use the stopwatch to measure the time to roll distance d 1 0 meter down the ramp. In one of your experiments you will roll a marble down a ramp to provide an initial horizontal velocity. My two hypotheses suggested that the surface texture of an inclined ramp would affect the distance traveled by a marble rolled down it and that the less textured the ramp s surface was the farther the marble would roll.

Long cardboard tube such as an empty roll of wrapping paper to make your ramp. Average calculated on rolls 2 3 and spare roll. For example rolls of tape markers plastic bottles different types of balls etcetera. See making measurements above.

It should be at least two and one. Investigating the speed of a marble rolling down a variable ramp introduction in this experiment i am going to investigate the speed of a marble rolling down a variable ramp. The input variable is the height of the ramp so i will keep everything the same except this factor.
