Answer:
A force is a basic requirement for the motion of an object.
Explanation:
Every object needs a push or pull on it to change its state of rest or to change its state of motion. This push or pull on the objects is termed a force. From Newton's 2nd law of motion, a force can be defined as the product of mass and acceleration of an object. The mathematical expression is given as:
F = ma
There are mainly two types of force. Contact and non-contact force. For a contact force, the objects have to be in contact with each other. (eg: Pulling a trolley). For a non-contact force, there is no need for the objects to be in contact with each other. (eg: gravitational force acting on an object).
