Inertia= Force it takes to change a state of motion
F=MA
Inertia Increases with Mass
M=Mass
F=Force

A=Acceleration
If Acceleration or mass increases in F=MA, divide M or A respectively by the other one
For every action, there is an equal and opposite reaction. The same is true for forces.
Types of forces
Applied Force=An acceleration. Constant speed does not= Applied force.
Tension=Force being held up from above The tension force is the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends. The tension force is directed along the length of the wire and pulls equally on the objects on the opposite ends of the wire.
Frictional Force-Force opposing motion
Gravity=Acceleration with which an objects mass pulls on another object. The Force gravity puts on an object is it's weight. On Earth, gravity is an acceleration of 9.8m/s/s
Friction=On all movement, needs to be overcome for a change in state of motion, increases inertia
Spring Force=force restoring an object to it's original or resting state
Air resistance=In any moving through the air
Applied Force=An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person.
Air resistance Formula D=C(D)A(PV^2)
Where D=Drag force,
C(D)=Drag coefficient
A=Area
P=Density of the fluid
V=Velocity
Sliding Friction Equation=Fsliding=Mewsliding*Fnorm
Static Friction Equation=Fstatic=Mewstatic*Fnorm
