Newton's Laws

Question 1

Weight

Answer 1

Gravitational force the Earth exerts on any object on or near its surface

Question 2

Normal force

Answer 2

The force or the component of a force which a surface exerts on an object with which it is in contact, and which is perpendicular to the surface

Question 3

Frictional force

Answer 3

The force that opposes the motion of an object and which acts parallel to the surface

Question 4

Static Frictional Force

Answer 4

The force that opposes the tendency of motion of a stationary object relative to a surface

Question 5

Kinetic Frictional Force

Answer 5

The force that opposes the motion of aa moving object relative to a surface

Question 6

Newton’s First law of motion

Answer 6

A body will remain in its state of rest or continue moving at constant velocity unless a non-zero resultant/net force acts on it

Question 7

Newton’s Second Law Of Motion

Answer 7

When a resultant/net force acts on an object, the object will accelerate in the direction of the net force. This acceleration is directly proportional to the force and inversely proportional to the mass of the object

Question 8

Newton’s Third Law Of Motion

Answer 8

When object A exerts a force on object B, then object B exerts a force on object A equal in magnitude but opposite in direction
