Kinetic Energy

Written by Jerry Ratzlaff on . Posted in Kinematics

Kinetic 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:

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

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