Newton's Law

Question 1

Newton’s First Law

Answer 1

states that an object continues in a state of rest or uniform velocity unless it is acted upon by an unbalanced force

Question 2

Newton’s Second Law

Answer 2

states that when a net force is applied to an object of mass, it accelerates in the direction of the net force. The acceleration is directly proportional to the net force and inversely proportional to the mass

Question 3

Newton’s Third Law

Answer 3

states that when object A exerts a force on object B, object B simultaneously exerts an opportunity directed force of equal magnitude on object A

Question 4

Newton’s Law of universal gravitation

Answer 4

states that each particle in the universe attracts every other particle with a gravitational force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between the centres.
