pomtj Retake questionStudents roll a tennis ball down two different ramps of equal height but differentangles as shown in the diagram below. Ignore friction.The students notice that the tennis ball rolls down the steeper ramp in less timethan the longer ramp. Which tennis ball has more kinetic energy at the bottom ofthe ramp? (5c1; DOK 1).The tennis ball on the less steep ramp has more KE because it can acceleratefor a greater time.LockedThe tennis ball on the steeper ramp has more KE because it exerts a greaterforce on the tennis ball.The tennis ball on the less steep ramp because the ramp is much longer, so itwould do more work.They would have the same KE since the change in PE is the same for bothtennis balls.

Concept explainers

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
