According to Newton's Second Law of Motion, the acceleration of an object is directly proportional to:
Its velocity
Its mass
Its displacement
Its position
Newton's Third Law of Motion states that for every action, there is an equal and opposite:
Reaction
Force
Acceleration
Momentum
Which of the following is an example of Newton's First Law of Motion?
