What is force? Force is the change in velocity with respect to time. Force is a push or a pull that usually causes distortion and/or acceleration. Force is the product of mass and velocity. Force is the ability to do work. Identify several of the forces that are acting on or around you.

Explanation:

A force can be defined as a push or a pull that usually causes distortion and/or acceleration. A force is a vector quantity because it has both magnitude and direction. Also, force typically causes an interaction (push or a pull) between two objects such as frictional force, gravitational force, tension force, electric force, normal force, magnetic force etc.

Mathematically, a force is given by the equation;

Where;

F represents force.

m represents the mass of an object.

a represents acceleration.

Thus, the acceleration (a) of an object of constant mass (m) is directly proportional to the amount of force acting on it or the degree of force exerted on it.

Additionally, the standard unit of measurement for a force is Newton (N).

Some examples of forces found around us are;

1. Force of friction holding nails and screws in desks, cabinets, walls, etc.

2. Weight (force of gravity) pulling down on everything.

3. Force of friction between you and your seat.
