Motion and Momentum

Question 1

Newtons first law of motion

Answer 1

An object stays at rest or moves with uniform velocity unless it is acted upon by an external force

Question 2

Newton’s second law of motion

Answer 2

The rate of change of momentum of a moving body is proportional to and in the same direction as the force acting on it

Question 3

What is Newton’s second law of motion equation

Answer 3

F= ma
F= (mv-mu)/ t

Question 4

Newton’s third law of motion

Answer 4

If an object A exerts a force on an object B then object B exerts an equal and opposite force on object A
