Question

Every action has equal and opposite reaction is Newton’s:
A) First law of motion
B) Second law of motion
C) Third law of motion
D) Fourth law of motion

Answer 1

Hint: Basically, this statement is from Newton laws of motion. Every action has an equal and opposite reaction connecting the force exerted by two bodies on one another. Remember different laws of motion describe different concepts.

Complete step by step answer:
If a body A exerts a force F on another body B, then the body B will exert a force ‘-F’ on A. Thus, the force exerted by A on B and that by B on A are equal in magnitude but opposite in direction.
For every action, there is an equal and opposite reaction. This statement means that in every interaction, there is a pair of forces acting on the two interacting objects. This is Newton’s third law of motion.
Hence, the correct answer is option C).

Additional information:
We can understand Newton third law of motion which is like every action has equal and opposite reaction by some daily life examples as:
Consider the flying motion of birds. A bird flies by use of its wings. The wings of a bird push air downwards. Since forces result from mutual interactions, the air must also be pushing the bird upwards. The size of the force on the air equals the size of the force on the bird; the direction of the force on the air downwards is opposite the direction of the force on the bird upwards. For every action, there is an equal in size and opposite in direction reaction. Action-reaction force pairs make it possible for birds to fly.
We can seat in chair this is possible only by concept of Newton third law of motion: the chairs exert a force upward on us and we exert force downward a chair by this simple example we are able to understand the concept, every action has equal and opposite reaction
Also, we walk on the ground. Our foot puts downward force on ground and ground exerts upward force that’s why we are able to walk on ground.

Note: Every action, simply we pull the wall by our hand means we are taking action against wall by pulling the wall now notice what is happening the wall also push means it also apply the force on our hand this basically means every action has equal and opposite reaction
Newton’s first law states that a body is said to be at rest or moving at a constant speed until and unless an external force is acted upon it.
Students often miss-interrupt it as an equal and opposite reaction and select an answer as option A). this will lead to the wrong answer.
