Kinetic Energy

energy PE KE MEKinetic energy, abbreviated as KE, is the energy an object possesses by virtue of its motion.  If it moves, it has kinetic energy.

 

Kinetic Energy Types

  • Mechanical Energy  -  The sum of the change in kinetic energy and potential energy generating from the force of gravity, external forces or the movement released in machine movement.
  • Radiant Energy (electromagnetic)  -  Energy transmitted without the movement of mass.
  • Sound Energy  -  Energy that we can hear.  It is a type of kinetic energy that moves through the air and other matter in the form of sound waves.

 

Kinetic energy formula

\(\large{ KE = \frac{1}{2} \;  m \; v^2  }\)
Symbol English Metric
\(\large{ KE }\) = kinetic energy \(\large{ lbf-ft }\) \(\large{J}\)
\(\large{ m }\) = mass \(\large{lbm}\) \(\large{kg}\)
\(\large{ v }\) = velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
