Newton's First Law of Motion
|
In the absence of any unbalanced applied force (Fnet = 0), a body at rest remains at rest and a body in motion continues in motion with the same velocity.
|
|
|
Inertia
|
The natural tendency of an object to maintain its state of rest or uniform velocity.

Newton's Second Law
|
ΣFx = m*ax
and ΣFy = m*ay Where ax and ay are the accelerations in direction x and y respectively. |

|
The 3 types of friction
|
Static Friction, Sliding (kinetic) Friction, and Rolling Friction
|
|
|
Force of static friction
|
Fs = μ N
Where μ is the coefficient of static friction and N is the normal force |
|
|
Force of Kinetic Friction
|
Fk = μ N
Where μ is the coefficient of kinetic friction and N is the normal force |
