Definition: Force Diagrams - Newton’s Laws Flashcards
1
Q
Weight (Fg)
A
The gravitational force the earth exerts on any object on or near it’s surface
2
Q
Normal force (Fn)
A
The perpendicular force exerted by a surface on an object in contact with it
3
Q
Frictional Force (Ff)
A
The force that opposes the motion of an object and acts parallel to the surface with which the object is in contact
4
Q
How to calculate max static friction
A
Ffs = us x Fn
5
Q
Newton’s first law
A
An object continues in a state of rest or uniform velocity unless it is acted upon by a net or resultant force
6
Q
Inertia
A
The property of an object that causes it to resist a change in its state of rest or uniform motion
7
Q
Newton’s third law
A
When object A exerts a force on object B, object simultaneously exerts an oppositely directed force of equal magnitude on object A
