Hint: The relation between force, energy and work is important to understand in physics, as most of the topics in physics depend on this relation. Each term has its own properties, but the application of it is interdependent, due to which none can exist without the use of the other. Basically, if the definition is known then writing the relation between force, energy and work becomes easy.
Complete answer:
Force is a push or a pull, and the displacement of an object due to the application of a force on it is called work. The ability to do work is called energy.
A force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons.
Energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity. The SI unit of energy is joule.
Work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, it is often represented as the product of force and displacement. A force is said to do positive work if (when applied) it has a component in the direction of the displacement of the point of application. A force does negative work if it has a component opposite to the direction of the displacement at the point of application of the force.
Note:
This type of question is basically asked to understand the understanding of the concept of the student, as this relation is the stepping stone to solve most of the questions in physics. This relation can be defined only when the definition of each term is clear, as the application of each term is related to each other.
