Newton's Laws

Question 1

Newton’s second law of motion

Answer 1

When a resultant/ net force 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 2

Newton’s third law

Answer 2

When object A exerts a force on object B, object B SIMULTANEOUSLY exerts an oppositely directed force of equal magnitude on object A.

Question 3

Newton’s law of universal gravitation

Answer 3

Every particle in the universe attracts every other particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Question 4

Newton’s first law of motion

Answer 4

An object continues In a state of rest or uniform velocity (moving with constant velocity) unless it is acted upon by a net or resultant force.

Question 5

Inertia

Answer 5

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