Which of the following is Newton’s Third Law?
For every action there is an equal and opposite reaction.
What goes up must come down.
The acceleration that a resultant force produces depends on the size of the force and mass of the object.
An object will continue to stay at rest or move with uniform speed unless a force acts on it.
