Newton's Laws And Application Of Newton's Laws

Question 1

Normal Force

Answer 1

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

Question 2

Frictional Force

Answer 2

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

Question 3

Static Frictional Force

Answer 3

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

Question 4

Kinetic Friction Force

Answer 4

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

Question 5

Newton’s First Law of Motion

Answer 5

A body will remain in a state of rest or motion at a constant velocity unless a net force acts on it

Question 6

Newton’s Second Law of Motion

Answer 6

When a net force acts on an object, the object will accelerate in the direction of the force at an acceleration directly proportional to the force and inversely proportional to the mass of the object

Question 7

Newton’s Third Law of Motion

Answer 7

When one body exerts a force on a second body, the second body exerts a force of equal magnitude in opposite direction on the first bofy
