Forces
Specific Situations
Circular Motion
Centripedal Acceleration
ac=(v^2)/r
Centripetal Force
Fc=m*ac
Pulleys
m1a=T-m1g
m2a=m2g-T
Inclined Planes
Fg (parallel) = mg*sin(theta)
Fg (perpendicular) = mg*cos(theta)
N equal to Fg but opposite
N2L Along the incline
a=g(sin(theta)-u*cos(theta)) (sliding down)
a=g(sin(theta)+u*cos(theta)) (sliding up)
Resistive Forces (a is not constant)
Fr=-bv
b is the drag coefficient
Newton's Laws
N1L
Inertia
Directly proportional to mass
Ability to resist change (acceleration)
Object in motion stays in motion
Net force = 0 (equilibirum)
N2L
F=ma
N3L
Every action has an equal &opposite reaction
Types of Forces
Force of Friction
m=Ff/Fn
Kinetic
Static
Fg
Force of gravity
(f=mg for force of gravity from the earth)
