NG070003
|
Assuming that no energy is transferred between a ball and the curved track it is moving in, or between the ball and the air around it, the ball will move to a height equal to the height from which it started.

NG075004
|
Assuming that no energy is transferred between a ball and the curved track it is moving in, or between the ball and the air around it, a ball on a curved track will reach a point as high as the point from which it started because as the ball moves down the track, its gravitational potential energy will change into motion energy, and as the ball goes up the other side, its motion energy will be changed back into an equal amount of gravitational potential energy.

NG085003
|
Assuming that no energy is transferred between a ball and the curved track it is moving in, or between the ball and the air around it, the ball will not have enough energy to go over a hill that is higher than the height from which it started because the total energy of the system has to remain the same.

NG086003
|
Assuming no energy transfer between a roller coaster car and the track it is moving in or between the car and the air around it, all of the hills that a roller coaster car can get over must be lower than the height of the starting point.

NG087004
|
A roller skater, who coasts down one hill and up another hill that is the same height as the first hill, will not have enough energy to reach the top of the second hill because some of her motion energy is transformed into thermal energy.

NG104002
|
Assuming no energy transfer between a ball and the track it is moving in, the speed of the ball will be the same before and after rolling down into and up out of a dip because the total amount of energy in the system does not change.

NG071003
|
Assuming that no energy is transferred between a ball and the curved track it is moving in, or between the ball and the air around it, the ball will move down the track and then up to a point equal to the height from which it started.
|
|
NG074004
|
Assuming that no energy is transferred between a ball and the curved track it is moving in, or between the ball and the air around it, the ball will move to a height equal to the height from which it started.
