Kinematics

Displacement vs distance, speed vs. velocity

Instantaneous vs average

Motion graphs

UAM

Free Fall

g

Fg

Air resistance/terminal speed/graphs

W = mg

FBD

Resultant force

Newton’s 1st

Equilibrium

Newton’s 2nd

F = ma

Inclined plane

Frictionless

FD

With friction

Elevator

p, impulse

F vs t graph

Conservation of p

Newton’s 3rd

Work

-done by force in the same direction as displacement

- done by force in different direction

-done by a spring (graph)

Work energy theorem

W = E W = KE W = U

Conservation of energy

Elastic/Inelastic

Power, efficiency

Uniform circular motion
