, Mechanics and Energy
Work (process which energy is transferred between systems) force x distance ( 1 Joules = N x m)
W = P∆V (Joules)
Power (the rate at which energy is transferred) Work/Time (1 Watt (W) = J/s)
Force x Velocity (W)
kinetic energy formula (motion; speed) KE=1/2mv^2 ( joules)
gravitation potential energy (object's position) U=mgh ( joules)
elastic potential energy (springs) U = 1/2 kx^2
frequency of a wave f = 1 / T (1/s = Hz)
