Kinetic Energy

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Kinetic energy is the energy in moving objects or mass.  If it moves, it has kinetic energy.

formula

\(KE = \frac {1}{2} m v^2 \) (Translational Kinetic Energy)

\(KE = \frac {1}{2} I w^2 \) (Rotational Kinetic Energy)

\(KE = \frac {P^2}{2m}\)

Where:

\(KE \) = kinetic energy

\(m\) = mass

\(v\) = velocity

\(I\) = moment of inertia

\(w\) = angle of speed

\(P\) = power

Solve for:

\(m = \frac {2   KE}{v^2} \)

\(v = \sqrt {   \frac {2   KE}{m} } \)
