Kinetic Energy

When mass and speed are doubled the $\mathrm{K}.\mathrm{E}.$ increases

The $K\mathit{.}E\mathit{.}$ acquired by a mass $m$ in travelling a certain distance $d$, starting from rest, under the action of a constant force is directly proportional to:

Kinetic energy of a body can be increased more by _____.

A shell explodes in mid-air. It's total:

A car starts from rest and moves on a surface with uniform acceleration. Draw the graph of kinetic energy versus displacement. What information you can get from that graph?

Is there any net work done by external forces on a car moving with a constant speed along a straight road?

An air molecule of mass $5.0\times {10}^{-26} \mathrm{kg}$ and moving with a speed of $500 \mathrm{m} {\mathrm{s}}^{-1}$ has a kinetic energy of about $\left(e=1.6\times {10}^{-19} \mathrm{C}\right)$

An object of $40 \mathrm{kg}$ mass is moving with $5 \raisebox{1ex}{$\mathrm{m}$}\!\left/ \!\raisebox{-1ex}{$\mathrm{s}$}\right.$ velocity. Now force is applied on the object such that its velocity increases to $10 \raisebox{1ex}{$\mathrm{m}$}\!\left/ \!\raisebox{-1ex}{$\mathrm{s}$}\right.$. Calculate the work done by the force in joules.

If the linear momentum is increased by $50\%$ then the kinetic energy will increase by

Kinetic energy of a body increases times when its momentum is increased  $\text{'}n\text{'}$ times.

Which of the following statements is correct?
1) Kinetic energy of a system can be changed without changing its momentum
2) Kinetic energy of a system cannot be changed without changing its momentum
3) Momentum of a system cannot be changed without changing its kinetic energy
4) Body cannot have energy without having momentum

A particle of mass $m_1$ is moving with a velocity $v_1$ and another particle of mass $m_2$ is moving with a velocity $v_2.$ Both of them have the same momentum but their different kinetic energies are $E_1$ and $E_2$ respectively. If $m_1>m_2$ then

If the momentum of a particle with fixed mass is doubled, its kinetic energy,
