Question

An isolated force does not exist. Explain this on the basis of Newton's third law of motion.
​

Answer 1

Answer:

Examples of Newton's third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices.

Newton's laws assume that the force on a body has its origin in other bodies, i.e., bodies have an influence on one another, which we attribute to an entity called force. Newton's third law of motion says that this influence is mutual : one body cannot influence another without itself being affected by that body.

An isolated force does not exist, i.e., forces act always in pairs, and simultaneously. Any of the pair can be called as action and the other as reaction. However, a given pair act on the two different interacting bodies; hence, they do not cancel each other.
