Newtons Laws And Application Of Newtons 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

The perpendicular force exerted by a surface on any object in contact with it

Question 3

Frictional force (due to a surface)

Answer 3

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

Question 4

Newtons first law

Answer 4

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

Question 6

Newtons second law

Answer 6

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

Question 7

Newtons third law

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.
