Newton’s laws

Question 1

Newton’s first law

Answer 1

An object continues in a state of rest or uniform velocity unless it is acted upon by a net or resultant force

Question 2

Inertia

Answer 2

The property of an object that causes it to resist a change in its state of rest or uniform motion

Question 3

Newton’s second law

Answer 3

When a net force, Fnet is applied to an object of mass, m, it accelerates in the direction of the net force. The acceleration, a, is directly proportional to the net force and inversely proportional to the mass

Question 4

Newton’s third law

Answer 4

When object A exerts a force on object B, object B simultaneously exerts an oppositely directed force equal magnitude on object A
