Question

what is the importance of second law and third law of motion

Answer 1

Dear Student,

Newton's second law of motion of Motion is very important because it shows the relationship between forces and motion. It allows you to calculate the acceleration (and therefore velocity and position) of an object with known forces.

Newton’s third law of motion characterises existence of force in pair only. This law states about an important characteristic of force rather than the relation between force and motion as described by the first two laws.
