Question

____ is the ability to do work.
A) Energy B) Simple machine C) Complex machine D) Force

Answer 1

D force is the ability to do work

Answer 2

A) Energy is the ability to do work.

Work is defined as a transfer of energy by a force acting on a body as it is displaced. The S.I. unit of Work is the joule (J).

• Let's discuss in detail, about Energy & its different types in detail.

• Energy is the property of matter that can be converted into work, heat, etc.
• Energy is required to complete a mechanical task. Hence, we can say that energy & work are the two sides of the same coin.
• when we do some work on a body, some amount of our energy is transferred, to the body.
• The body on which work is done, gains energy.
• We know that, energy cannot be created nor be destroyed, it can only be transferred from one form of energy to another & even can be transformed into other forms of energy.
• Energy can exist in a wide range. All types of energy are either dynamic or potential.  The types of energy: Kinetic Energy, Potential energy, etc.

• Kinetic Energy: The Energy by the virtue of its motion is called kinetic energy. The Work done by a force in displacing a body measures the change in the Kinetic energy of a body.
• In simple words, When a force does some work the kinetic energy of the body increases by the same amount. While Kinetic energy decreases when work is done by the body against an opposing force.
• Potential Energy: The Energy by the virtue of its position is called potential energy. i.e. the energy stored within the objects such as stretched springs, etc.
• Thermal energy: The Flow of heat via matter is called Thermal Energy.

         

Hence, Energy is the ability to do work.
