Answer:
C. Newton's law of inertia
Explanation:
Law of inertia, also called Newton’s first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
Answer:
Newton's law of inertia
Explanation:
This states that, a body will continue to be at rest or moving at a constant speed in a straight line, unless it is acted upon by a force.
The force could be internal or external.
Since the player's one hand can't produce the desired effect on the tennis ball and his two hands can produce more force to put the tennis ball in motion, then the law of inertia is being obeyed here.
