Weight
if lbs, leave it alone as is
Work
even e=mc2 is work, dont forget
Kinetic Energy
rotational..
Potential Energy
Power
P = W/t = force*velocity
Actual Mechanical Advantage
Ideal Mechanical Advantage
Mechanical Efficiency
Friction Force
F = uN (where F can be tension or mass*acceleration) (where N is weight)
Belt Friction
Spring Force
k=m(omega)^2
Spring Potential
Rest Energy
E = mc2
Gravitational Force
g*(earth radius/ earth radius + height)^2
Wave Velocity
relate to sound velocity as much as you can. wavelength=2(l) or wavelength=2(l) when closed air
Wave Velocity given molar mass
Wave Velocity given tension
Uniform Motion
V = d / t
Non-uniform Motion
Free fall Equations
Projectile Equations
Wall Plant
Rotary Motion
angular velocity = 2pi*f; angular velocity = 1/r * sqrt(pressure/density)
Centripetal Force
Centripetal Acceleration
also normal acceleration

A man can exert a max pull of 1000N but wishes to lift a new stone door for his cave weighing 20kN. If he uses lever, how much closer must the fulcrum be to the stone than to his hand (Ans: 20x nearer)
use fodo/fidi
