For every action there is an equal and opposite reaction. What does these words imply?

Answer: Newton's third law of motion

Explanation:

Newton's third law of motion states that, "for every action, there is an equal and opposite reaction"

This means that in every interaction, a pair of forces usually acts on the two interacting objects. Every action that happens or takes place, has an opposite reaction to it, which is also equal.

Example, take a look at the motion of a vehicle on your way to school. The vehicle has wheels that spin. As the wheels spin, they grip the road and push the road backwards. The road then pushes the wheels forward, since forces results from mutual interactions. The size of the force on the road is equal to the size of the force on the car; the direction of the force on the wheels (forwards) is opposite the direction of the force on the road (backwards)

"For every action, there is an equal but opposite reaction" is the 3rd Netwon's law of motion.

Examples of Newton's third law of motion are found in our everyday life. For example,

• Gun Firing: when someone fire gun the reaction force push the gun backward.

• 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 find numerous applications in Newton's third law when designing rockets and other projectile devices.
