Newton'
law states that when one object exerts a force on a
second object, the second object always exerts a force back on the first
object that's equal in magnitude and opposite in direction.

His third law was the one that explained that.

Explanation:

Newton realized that forces are not one-sided. Whenever one object exerts a force on a second object, the second object exerts a force back on the first object. The force exerted by the second object is equal in strength and in the opposite direction to the first force.

Hope this helped :D
