Newton's Laws

Question 1

Weight

Answer 1

The gravitational force the earth exerts on any object on or near its surface

Question 2

Normal force

Answer 2

H perpendicular force exerted by a surface on an object in contact with it

Question 3

Frictional force

Answer 3

The force that opposes the motion of an object and act parallel to the surface with which the object is in contact

Question 4

Newton’s first law of motion

Answer 4

An object continues in a state of rest of constant velocity unless acted upon by a net 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

Question 6

Newton’s second law of motion

Answer 6

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

Question 7

Newton’s third law of motion

Answer 7

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