When does an object have NO kinetic energy? 

• When it has no electrical charge 

• When it’s at rest 

• When the only force that’s acting on it is gravity 

• When it’s moving very slowly 

If two objects of different masses are dropped from the same elevation (height), at the same speed onto the same surface, the one with the greater _________ will have a greater impact, resulting in more KE.

• elevation (height)

• speed 

• time

• mass
