Newton's Laws of Motion

Question 1

Newton’s First Law

Answer 1

Inertia

A body remains at rest or travelling in a straight line at constant speed unless acted upon by an external (net/unbalanced) force

Question 2

Newton’s Second Law

Answer 2

F = ma

Net force is directly proportional to acceleration and mass

Question 3

Newton’s Third Law

Answer 3

Equal and opposite reaction (action/reaction pair)

If object A exerts a force on object B, object B exerts a force of equal magnitude and in the opposite direction on object A.
