P = dW/dt ; Power is the time derivative of work. standard makeup vanity height

"WebbAn object is accelerating if it is changing its velocity. As velocity is an example of vector, it has direction and magnitude. So we can explain the acceleration in any of these three ways: a change in direction (from East to North-East) a change in both speed and direction (from 34 km/h East to 12 km/h West) " - Physics acceleration and velocity problems
