• hit

• strike

• collision

When two moving objects collide, the motion of both objects will change. Why does this happen?

• Energy is transferred from one object to another.

• Friction changes when moving objects collide.

• Object lose mass when they collide, so they weigh less.

• The motion of all objects is changing all of the time.
