Forces

Question 1

Weight (Fg)

Answer 1

The gravitational attraction the Earth exerts on any object on or near its surface.

Question 2

Normal Force (FN)

Answer 2

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

Question 3

Frictional Force (Ff)

Answer 3

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

Question 4

Maximum Static Friction

Answer 4

The maximum amount of friction that can keep an object in equilibrium. The maximum static friction is the amount of friction acting on a system when the object is just about to move. As the forces that setting the object in motion increase, the static friction increases to the maximum static friction.

Question 5

Kinetic Friction (not SAGS)

Answer 5

The force that opposes the motion of a moving object relative to the surface with which it is in contact
