How can waling on earth be an example of thirld law of motion]

Answer»

Newton's 3rd law of motion STATES that:

“For every action there is an equal and opposite reaction.”

It means that for every interaction between objects there are always 2 forces ACTING. The forces must be equal in magnitude. That is they must both be EQUALLY "strong." They also must be opposite - working in OPPOSING directions.

When we walk our foot pushes on the floor and the floor pushes back on us - in the opposite direction, RESULTING in our moving in the direction we are walking.

It's a little difficult to understand that this happens anytime we have an interaction between objects. When we sit down on a chair, the chair pushes up on us. And, of course, when we hit someone, he/she's going to hit us back
