Create
torque
T=FD
_{┴ }
torque is force times moment arm
both the magnitude of the force and the length of the moment arm equally effect the outcome of torque
momentum
M=mv
quantity of motion
linear velocity
v=rw
angular velocity
ω=v/r
ω=θ2-θ1/Δt
who wins collision equation (momentum of both objects is given.. which direction wins?)
v=(m1v1+m2v2)/m1+m2
or think of it as v=(M1+M2)/m1+m2
what do you to for degrees to radians
divide
what do you do from radians to degrees
multiply
work
W=Fd
creating force over distance
power
P=W/Δt or P=Fd/Δt
work over time
kg to newton conversion
1kg=9.8N
Impulse
Ft=ΔM or Ft=mv2-mv1
change in momentum
angular momentum
H=Iω
quantity of angular motion
Inertia
I=mr
^{2}
or I=Σmr
^{2}
sometimes r is replaced with k
resistance to motion
Φ
angular distance
θ
angular displacement
α (alpha-fishy)
angular acceleration
ω
angular velocity
σ
angular speed
t
time
T
torque
v
linear velocity
d
distance/displacement

F
force
F
_{m}

amount of force for maximal static friction
F
_{m}
=μ
_{s}
R
amount of force for kinetic friction
F
k
=μ
k
R
force
F=ma
angular acceleration
α=ω2-ω1/Δt
or
α=Δω/Δt
