The change in velocity divided by an elapsed time

• average acceleration

• force

• mass

• unit is m/s

If force is held constant when mass is halved, what will the acceleration be?

• doubled

• stays the same

• halved as well

• decreased

What is the condition in which all forces balance?

• equilibrium

• dead end

• inertia

• gravity

As an object freely falls downward, its

• Acceleration increases

• velocity increases

• mass increases

• size increases

The energy possessed by a body by virtue of its position relative to others

• kinetic energy

• potential energy

• chemical energy

• friction

The total distance covered divided by the time is called:

The force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other

• friction

• gravity

• resistance

• viscosity

An object either remains at rest or continues to move at a constant velocity unless acted upon by a net force

• Newton's second law

• inertia

• equilibrium

• gravitational force

• kinetic energy

• mechanical energy

• potential energy

• electrical energy
