Question

Distinguish between: Real force and pseudo force.

Answer 1

Hint:Here, we need to find the difference between the real force and pseudo force. For this, we will use the definition of both the terms and then we will use their properties for other differences in order to get better understanding and clarification.

Complete step by step solution:Force is defined as the push or pull upon an object resulting from the object's interaction with another object. Force is represented by F. Force plays a very important role in the establishment of Newton’s laws of motion. Real forces are the forces that act on the body (in a direct manner). Force is defined as the product of mass (represented by m) and acceleration (represented by a).
S.I. unit of force is Newton (represented by N)
Real force arises because of the actual interaction (i.e. real interaction) of the objects in the same reference point.
While pseudo forces are not real. They are imaginary forces. Pseudo forces arise because of the change in the reference point. It is defined as the product of the mass (represented by m) of the body and the relative acceleration of the body with respect to the specific reference point (represented by${{\text{a}}_{\text{r}}}$).

Note:Pseudo force is a theoretical concept. It is not applied to the body directly. It is used for solving the problems for example in free body diagrams. Pseudo Force is also known as fictitious force, inertial force or d'Alembert force. It is an apparent force which actually acts on all masses whose motion is described by using non-Inertial frame of reference which is undergoing acceleration with respect to an Inertial frame.
