Question

The rate at which work is being done is called:

Options
  • A

    Power

  • B

    Energy

  • C

    Density

  • D

    Force

Explanation

The rate at which work is done is called power. It is expressed as the amount of work per unit of time.

The rate at which work is done is called power. It is expressed as the amount of work per unit of time.

In physics, energy is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.

Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume.

A force can cause an object with mass to change its velocity, i.e., to accelerate.
