You are not expected to complete the 5E’s in one day or lesson. While it is not really possible to have an object with all of its mass at the center, it is possible to make one in which most of the mass is near the center, which reduces the moment of inertia. Rolling on Different Surfaces. Build a ramp with your child by propping up one end of a large picture book or a piece of cardboard. Roll the beaker slightly towards you (the top of the ramp), without letting go of it. Time how long it takes for the golf ball to hit the floor after your let the ball go. Develop a hypothesis in regard to which ramp will make the ball roll farther. Use a dashed line to show the acceleration of the cart from the previous project, and a solid line to show your prediction for ion of the the accelerat more massive cart. Set up the ramp so that a ball can roll down the ramp, across a short section of the table, and off the table edge. [ The independent variable is the angle of incline and the dependent variable is the distance the ball rolls. Data, Table [d] [t] The ball will be released from the bottom of the ramp, a quarter of the way up the ramp, half-way up the ramp, three-quarters of the way up the ramp, and from the top of the ramp. Measure distance from bounce 1 to bounce 2. You have probably watched a ball roll off a table and strike the floor. We set up the same ramp that we used for our friction experiment. Record the distance the cup moves on table 1. The cart is initially held by the physics teacher's hand at the top of a ramp (The 5 book ramp in particular). Problem: Do lighter or heavier cars (or balls) go farther when rolled down the same ramp? Research: Look up information about ramps and momentum. For a ball shot with an initial speed of 8. Assuming it is the length of the ramp itself, then the height would be 4. (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. We performed a similar experiment in the beginning of our first term discussing the relation of height of a slope and the final velocity of a ball rolling on it . Instead of dropping a rock off a bridge he allowed a ball to roll slowly down a ramp. Just like a ball, water flows more easily and more quickly down a ramp. The top of the ramp was placed at different heights above the floor (that is, the length of the ramp varied), and Galileo. Which best describes the motion of the tennis ball? It does not exhibit projectile motion and follows a straight path down the ramp. Rolling ball down ramp to calculate acceleration of gravity. In each case the ball was launched from an inclined ramp, and accurate measurements were made of a number of distances. This lab seeks to confirm the conservation of linear momentum. Hold the toy car at the top of the ramp, aligning the back of the car with the edge of the ramp.
