So power = energy รท time. [\text{power}={\text{voltage}}\times{\text{current}}] p = v ร i. Weight (n) = mass ร gravitational field strength.
Spice of Lyfe Physics Calculating Work Done
Remember, v = i ร r, so by. (energy) power= work done/time taken. [power = \frac {work \ done}{time \ taken}] [p = \frac {e}{t}] this is when: P = e รท t power = energy รท time.

This equation can be rearranged with the help of a formula triangle: E = c x m x ฮธ. This heat is then lost to the environment, it is wasted energy. Moment of a force = force x distance normal to the direction of the force Power = energy transferred + time taken electrical power current x potential difference electrical.
