True

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

False

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

False

Any time the forces are unbalanced, an object will remain at rest.

True

According to Newton's first law of motion, an object at rest will stay at rest until a net force acts upon it.

True

According to Newton's first law of motion, an object moving at a constant speed in a straight path will continue to do so until a net force acts upon it.

True

Friction brings most moving objects to a stop.

True

Friction will never speed up an object.

False

Galileo believed that the natural state of an object was to be at rest.

False

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

True

Walking would be impossible without rolling friction.

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

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

True

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

True

Friction can be reduced but never eliminated.

gravity

___ exists between any two objects that have mass.
