action and reaction are equal and opposite and they act on?
Answers
Answer:
A force is a push or a pull that acts upon an object as a results of its interaction with another object. ... These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.
Hello there!
Answer:
According to Newton's third law of motion, every action has an equal and opposite reaction.
For example, when we walk we exert a force on the ground and similarly, an equal and opposite force is exerted by the ground on our foot that pushes us forward enabling us to walk.
Coming on to your next question, these forces actually act in pair and on different bodies. Action-Reaction forces are of same nature. Generally, when there is a contact between two bodies, normal reaction works.
Consider an example a block is at rest on a surface, normal reaction denoted by (N) is exerted on the surface and similarly the surface also exerts an equal and opposite (N) on the block, thus they act in pair and are acting on different bodies.
