CONCEPT:

  • Kinetic energy (KE): The energy possessed by a body by virtue of its motion is called kinetic energy.

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

Where m = mass of the body and v = velocity of the body

EXPLANATION:

  • A ball thrown upwards has some velocity so it has kinetic energy.
  • A battery is always at rest. It doesn't possess kinetic energy. The battery has chemical energy inside it.
  • A moving car has some velocity so it possesses kinetic energy.
  • A flying bird also has some speed. So possess kinetic energy.
