returning (to original position)

A stack of blocks remains nearly in place when the bottom block is quickly knocked away. Which idea BEST explains this?

The blocks resist a change in motion because of inertia

The blocks exert greater force because they have less mass

The blocks move because of an action-reaction pair

When a car goes around a corner at 20 mph, why do we say it accelerates?

The car is accelerating because it's changing direction

The car is accelerating because of the velocity is constant

The car accelerates because it's going 20 mph

Cars always accelerate when they are in motion
