Kinetic Energy

Written by Jerry Ratzlaff on . Posted in Kinematics

energy PE KE MEKinetic energy, abbreviated as KE, is the energy in moving objects or mass.  If it moves, it has kinetic energy.

Kinetic Energy formula

(Eq. 1)  \(\large{ KE = \frac {1}{2} \; m \; v^2 }\)         

(Eq. 2)  \(\large{ KE = \frac {P^2}{2 \; m}   }\)         

Where:

\(\large{ KE }\) = kinetic energy

\(\large{ m }\) = mass

\(\large{ P }\) = power

\(\large{ v }\) = velocity

Solve for:

\(\large{ m = \frac {2 \;  KE}{v^2} }\)

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