Question

Identify the action-reaction pairs in the following situations.

Answer 1

In physics, action-reaction pairs are observed in various situations. Examples include the gravitational forces between Earth and the Moon, the forces involved when a boy kicks a football, and the rocket's engines pushing exhaust gases during upward acceleration. These action-reaction pairs follow Newton's third law of motion.

Step-by-step explanation:

Action-Reaction Pairs in Different Situations:

1. In the situation where Earth attracts the Moon, the action force is the gravitational force exerted by Earth on the Moon, and the reaction force is the gravitational force exerted by the Moon on Earth.
2. When a boy kicks a football, the action force is the force exerted by the boy's foot on the football, and the reaction force is the force exerted by the football on the boy's foot.
3. For a rocket accelerating upward, the action force is the force of the rocket's engines pushing exhaust gases downward, and the reaction force is the force exerted by those gases pushing the rocket upward.

These action-reaction pairs follow Newton's third law of motion, which states that for every action force, there is an equal and opposite reaction force.
