O A. The balls will both stay at the top of the ramp. O B. Ball B will roll farther than Ball A. O C. Ball A will roll farther than Ball B. O D. Both balls will roll the same distance. 2. Explain your answer for question number 1. ___Student responses will vary, but should contain the idea that the ball A will have rolled the farthest because it has more mass, therefore containing more potential energy, which transfers to more kinetic energy and takes the ball longer to be slowed down by the force of friction. 3. Car X is driving slowly down a road when it runs into another car (Car Y) the same size as itself. Car Y is sitting still, but is not applying its brakes. What will happen when the cars collide? O A. Car X will stop and Car Y will roll forward. O B. Car X will bounce backward and Car Y will stay where it was. O C. Cars X and Y will both roll forward. O D. Car X will stop and Car Y will not move. 4. Two identical balls are placed at the top of two ramps and then released. Ramp A has a height of 10cm. Ramp B has a height of 25cm. Which ball will have rolled the farthest after it is released down the ramp? Explain your answer. ___Student responses will vary, but should contain the idea that the ball rolling down Ramp B will have rolled the farthest because its starting point is higher. The higher the ramp, the more potential energy the car will have due to the force of gravity.
