Energy, Work, and Power
In Physics, "Work" has a very specific definition: it only happens if an object moves in the direction of the force.
Work Done: W = F . s (where s is displacement)
Kinetic Energy: E_k = 1/2mv2
Potential Energy: E_p = mgh (where g = 9.8 m/s2)
Power: P = W/t (measured in Watts)
