Which among the following is a form of energy?

The kinetic energy of a body of mass $4 \ kg$ moving with a velocity of $(2 \hat{i}-4 \hat{j}-\hat{k}) \ ms^{-1}$ is (in $J$)

Express momentum in terms of mass and kinetic energy.

When the mass and speed of the body are doubled,the kinetic energy of the body

Two bodies of masses $m_1$ and $m_2$ have equal kinetic energies. If $p_1$ and $p_2$ are their respective momenta,then the ratio $p_1:p_2$ is equal to

The kinetic energy possessed by a body of mass $m$ moving with a velocity $v$ is equal to $\frac{1}{2}mv^2$,provided
