Question

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

• A. The body moves with velocities comparable to that of light
• B. The body moves with velocities negligible compared to the speed of light
• C. The body moves with velocities greater than that of light
• D. None of the above statement is correcst

Answer 1

The correct option is B

The body moves with velocities negligible compared to the speed of light

If the particles move at a speed comparable to speed of light, then Newtonian mechanics does not hold good.
