Make Sense of Your ideas1. In general, how can you increase the motion

energy of an object?

You can increase the motion energy of an object when the source transfers energy INTO to receiver. Example:

2. In general, how can you decrease the motion energy of an object?

You can decrease the motion energy of an object when the energy is transferred OUT of the object. Example:

Our Consensus IdeasHow can you change (increase or decrease) the motion energy of an object?

Mechanical interactions (applied, friction, drag, elastic) can cause changes in motion energy. An object will increase in motion energy when it receives a push or pull from the source. Also, an object will decrease in motion energy when it transfers energy to the receiver.
