---|---|---|
The motion energy of an object depends on the speed and mass of the object. |
||
Both a ball that is thrown and a ball that is dropped have motion energy while they are moving. |
||
A ball has more motion energy than a person when the ball is moving and the person is not moving. |
||
Increasing the speed of an object increases its motion energy. |
||
A car has the most motion energy when it is traveling at the highest speed. |
||
For two balls that have the same mass, the ball that is rolling faster has more motion energy. |
||
For two balls that have the same mass, the ball that is rolling faster has more motion energy. |
||
For two pinecones falling at the same speed, the pinecone with more mass has more motion energy. |
