Question 1(ii)

The kinetic energy of a given body depends on the :

  1. position
  2. centre of gravity of the body.
  3. momentum
  4. displacement
Answer

momentum

Reason — As,

Kinetic Energy=12mv2\text {Kinetic Energy} = \dfrac{1}{2}\text m \text v^2

And,

Momentum (p) = mv

Then,

Kinetic Energy=12mm2v2=p22m\text {Kinetic Energy} = \dfrac{1}{2\text m}\text m^2 \text v^2 = \dfrac{p^2}{2\text m}

So, the kinetic energy of a given body depends on its momentum.
