Which is not a force?

• friction

• momentum

• gravity

• weight

You push on a box and are unable to move it. What force opposes your push?

• static friction

• rolling friction

• sliding friction

• air resistance

Air resistance depends on

• the velocity of a moving object.

• the weight of a moving object.

• the mass of a moving object.

• the inertia of a moving object.

What force besides gravity acts on a projectile?

• weak nuclear

• electrical

• magnetic

• air resistance

Newton's first law of motion is sometimes called the law of

• inertia.

• conservation.

• momentum.

• resistance.

A change in which of the following affects the weight of an object?

• momentum

• velocity

• acceleration due to gravity

• friction

Which represents Newton's second law?

For every action force there is a

• reaction force.

• net force.

• friction force.

• unbalanced force.

Momentum depends upon

• force only.

• velocity and friction.

• weight and mass.

• mass and velocity.

What force holds the nucleus together?

• magnetic

• strong nuclear

• gravitational

• centripetal
