Calculate the kinetic energy of a body of mass $2 \, kg$ moving with a velocity of $0.1 \, m s^{-1}$. (in $, J$)

Name at least six forms of energy.

$A$ force of $10\, N$ moves a body with a constant speed of $2\, m s^{-1}$. Calculate the power of the body.

Calculate the power of an engine required to lift $10^{5} \text{ kg}$ of coal per hour from a mine $360 \text{ m}$ deep. [Take $g = 10 \text{ m s}^{-2}$]

Define work. Write an expression for work in terms of force and displacement. State the $SI$ unit of work done.

$A$ car is accelerated on a levelled road and attains a velocity $4$ times of its initial velocity. In this process,the potential energy of the car
