potential energy
Ep = mgh
kinetic energy
Ek = (½)mv2
mechanical energy
Em = Ep + Ek
the law of conservation of energy
Emi = Emf
joules
J = (kg)(m2/s2)
solving for velocity using the kinetic energy equation
v = sqrt(2Em/m)
solving for mass using the kinetic energy equation
m = 2Ek/v2
force (Newtons)
F = (kg)(m/s2)
net force
Fnet = ma
acceleration
a = (vi - vf)/t or the slope of a v-t graph
velocity
v = m/s or the slope of a p-t graph
efficiency
Eff% = (Output/Input)100
work
W = Fd(cos θ)
θ = +1 if positive work done
θ = -1 if negative work done
