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.
|
 |
NG067003
|
As a ball rolls back and forth along a curved track and the ball and track get a little warmer, the total energy of the ball and track system does not change because no energy was added or released from the system.
|
|
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.
|
|
NG076004
|
The total amount of energy in a system remains the same unless energy enters or leaves the system.
|
|
NG078003
|
After a rubber band is used to shoot a toy car across the floor, the total energy of the system will remain the same because the increase in the motion energy (kinetic energy) of the car is the same as the decrease in the elastic energy of the rubber band.
|
|
NG080004
|
As a clay ball falls and hits the ground, the total amount of energy in the system stays the same because the decrease in energy due to the clay ball moving closer to the ground is equal to the increase in energy due to the clay ball and the floor getting warmer.
|
|
NG081004
|
The total energy inside a closed cooler filled with ice and a can of soda stays the same even though the can of soda gets colder, because the amount of energy that the can of soda lost is equal to the amount of energy that the ice gained.
|
|
NG082004
|
When an apple falls from a tree, the apple has less energy when it is on the ground that it did when it was on the tree.
|
|
NG083004
|
Energy is transferred to the air around hot food as the food cools even though the temperature of the air does not appear to increase.
|
|
NG088004
|
When a student shoots a rubber band across the room, the elastic energy of the rubber band is transformed into motion energy, and the total amount of energy stays the same. (This item uses bar graphs to depict the amount of each kind of energy.)
|
|
NG089004
|
The total amount of energy in a lunch box containing only an ice pack and the air around it remains the same even after the ice pack gets warmer and the air gets colder. (This item uses bar graphs to depict the amounts of each form of energy.)
|
|
NG092003
|
Assuming no energy transfer between a ball and the track it is moving in, the amount of energy the ball has after it goes over a hill will be the same as before it went over the hill.
|
|
NG093003
|
Assuming no energy transfer between a ball and the track it is moving in, the amount of energy the ball has after it goes over a hill will be the same as before it went over the hill because the total amount of energy in the system did not change.
|
|
NG094003
|
Assuming no energy transfer between a ball and the track it is moving in, the amount of energy the ball has after it goes over a hill will be the same as before it went over the hill because the total amount of energy in the system did not change.
|
|
NG095003
|
The total amount of energy a ball has does not change after it goes down and up a dip because the total energy of the system (ball and track) does not change (assuming no energy transfer between the ball and the track and the ball and the air around it).
|
|
NG096003
|
The total amount of energy a ball has does not change after it goes down and up a dip because the total energy of the system (ball and track) does not change (assuming no energy transfer between the ball and the track and the ball and the air around it).
|
|
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.
|
|
NG069005
|
In a situation involving two slides, and assuming no energy transfer between the slides and the students sliding on them or between the students and the air around them, two students of the same mass sliding down differently shaped slides will have the same speed at the bottom of the slides because the only source of motion energy is the change in gravitational potential energy, and both students experience the same change in gravitational potential energy.
|
|
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.
