newtons

Force is measured in ____.

True

Friction brings most moving objects to a stop.

True

Friction can be reduced but never eliminated.

True

Friction will never speed up an object.

True

If an object is not moving, the net force working on it is zero.

True

If an objects accelerates, a push or pull must be acting on it.

False

If two forces are in the same direction, they cancel each other out.

False

If you slide a bag of groceries along a countertop, you must first overcome rolling friction.

mass

In the formula a= Fnet divided by m, the m stands for ____.

force

In the formula a=Fnet divided by m, the Fnet stands for___.

False

Rolling friction always reduces the net force acting against an object's motion to zero.

False

Sliding friction is caused by the attraction between two surfaces.

True

When the net force is zero, the forces on an object are balanced.
