### Kinetic Energy Calculator

Kinetic Energy is the energy an object has owing to its motion. In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 ...

### SAGMILLING.COM .:. Mill Critical Speed Determination

Mill Critical Speed Determination. The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell.

### Power | Work, energy and power | Siyavula

At the bottom of the stairs, we take both $$E_k$$ and the potential energy due to gravity, $$E_{p,g}$$, as initially zero; thus, $$W=E_{k,f}+ E_{p,g}=\frac{1}{2}mv_f^2+mgh$$, where $$h$$ is the vertical height of the stairs. Because all terms are given, we can calculate $$W$$ and then divide it by time to get power.
