Question

Name the branch of Science which explains force and displacement.

Answer 1

Force:

1. Force is a physical quantity that changes or may try to change the state of rest or the state of motion of an object.
2. The S.I. unit of force is Newton.

Displacement:

1. It may be defined as the change in the position of an object from the initial to the final position.
2. It is a vector quantity and has both direction as well as magnitude.
3. It can be represented by an arrow that points from the starting position to the final position.

Branch of Science:

1. Mechanics is the branch of science that tells us how the body behaves when the body undergoes effects of force, displacement, etc.
2. It includes Kinematics, Projectiles, Circular Motion, Uniform and Non-uniform, relative Velocity, Newton’s Law of Motion, Law of gravitation, Center of Mass, Collisions, rotational Motion, fluid Mechanics and much more.

Thus, the branch of Science which explains force and displacement is mechanics.
