Total questions: 12
Worksheet time: 10mins
Students dropped a ball from differents heights and recorded the bounce height of the ball. Click on the graph to look at their data.
Describe the relationship between drop height and gravitational potential energy.
The higher the drop, the less potential energy in the ball
The higher the drop, the more potential energy in the ball.
The lower the drop, the more potential energy in the ball.
Height and potential energy are different, so there is no relationship.
Hypothesize: If the students would have thrown the ball at the floor, instead of dropping it freely, would this have changed the height the ball
reached?
Yes, because the throw adds energy to the ball.
No, because it is released from the same height.
Hypothesize: If it had been a 50 lb bouncy ball, would this have changed the height
the ball reached?
No, because it is dropped from the same height.
Yes, because gravitational potential energy depends on both height and mass/weight.
The formula for Gravitational Energy is Height x Weight. Knowing this,which has the GREATEST gravitational potential energy?
An elephant standing on Mount Everest
An orange sitting on a four foot bookshelf
An orange sitting on a six foot bookshelf
A toothpick sitting on a four foot bookshelf

A. Students sit a ball on a platform. (a) energy is at its maximum and (b) energy is at its minium. When they tap the ball and it begins to fall, (c) energy increases and (d) energy decreases.s
When the ball reaches the floor (a) energy is at its maximum and (b) energy is at its minimum.
As the ball bounces and begins to rise up, (a) energy increases and (b) energy decreases.
During the student's experiment, the energy in the balls transforms between potential and kinetic, but the TOTAL amount of energy in the ball never changes, because energy cannot be (a)
