In physics, what is the definition of work done on an object by a constant force?

The product of the force and the time over which it is applied.

The product of the mass and the acceleration of the object.

The rate at which energy is transferred.

The product of the force and the distance moved in the direction of the force.

Gravitational potential energy depends on which three quantities?

Mass, gravitational acceleration, and height

Mass, specific heat, and temperature

be used up completely in a reaction.

increase over time in a closed system.

change from one form to another.

be converted directly into mass.

The total amount of energy an object has.

The force applied over a certain distance.

The rate at which work is done or energy is transferred.

When the force is perpendicular to the displacement.

When the force is in the opposite direction to the displacement.

When the force is applied by a non-conservative force.

It depends on the mass of the box.

A positive amount, because force is being applied.

A negative amount, because of fatigue.
