Question

Distinguish between Real force and the Pseudo Force.

Answer 1

Hint: In this question, we need to distinguish the Real force and the Pseudo forces. For this, we will use the definition of both the key terms and use the properties of the same for better clarification.

Complete step by step answer:
A force is the push or pulls on the body. It plays a very vital role in the establishment of Newton’s equation of motion.
Real forces are the forces that act on the body directly. It is measured as the product of the mass of the body and the acceleration of the body itself. Mathematically, $F = ma$ where ‘m’ is the mass of the body moving with an acceleration of magnitude ‘a’. It arises due to the actual interaction of the objects in the same reference point. It is measured in Newton.
Pseudo forces are the imaginary forces that act on the body due to change in the point of reference. It is measured as the product of the mass of the body and the relative acceleration of the body with the specified point of reference. Mathematically, ${F_\rho } = m{a_r}$ where ‘m’ is the mass of the body, which is moving with an acceleration of $'{a_r}'$ relative to the frame of reference. It is not applied to the body directly; rather, it is just a theoretical force to ease in solving the problems.

Note:Though pseudo force cannot be applied to the body directly, but it plays a very crucial role in the free body diagram of the body in some other frame of reference. Moreover, the pseudo force is denoted by a Greek letter rho, i.e., $\rho $.
