"an object that is at rest will remain at rest, an object that is moving will continue to move in a straight line with constant speed, if and only if the net force acting on that object is zero"
What is Newton's First Law?
100
Add vectors by placing them tip-to-tail then connecting the tail of the first vector to the tip of the second vector.
How to Find The Resultant?
100
The force that has a limit on how large the friction can be.

200
A force that puts an object in equilibrium

200
Needed to calculate the force of kinetic friction.
What is the coefficient of kinetic friction?

Motionless or Moves with Constant Velocity
What is an object in equilibrium?
300
The force that is exerted on one surface by another when the two surfaces rub against each other because one or both of them are moving.
