The kinetic energy of an object of mass, m moving with a velocity of \(5\ ms^{-1}\) is \(25\ J\). What will be its kinetic energy when its velocity is doubled? What will be its kinetic energy when its velocity is increased three times?
If a body of mass \(m\) is moving with a speed \(v\), then its Kinetic Energy. \({E_k}\) is given by the expression,
Mass of the object (\(m\)) \(=\) \(kg\)
When velocity is doubled, Kinetic energy of the object \(=\) \(J\)
When velocity is increased three times, Kinetic energy of the object \(=\) \(J\)
