List of top Physics Questions on Work-energy theorem asked in KEAM

A body of mass \( 0.2\,\text{kg} \) travels along a straight line with velocity \( v = (2x^2 + 2)\,\text{m s}^{-1} \). The net work done by the driving force during its displacement from \( x = 0 \) to \( x = 2 \,\text{m} \) is

A ship of mass \(2\times10^7\) kg initially at rest is pulled by a force of \(5\times10^5\) N through a distance of \(2\) m. Assuming that the resistance due to water is negligible, the speed of the ship is

The Work-Energy theorem

A vehicle moving at 36 km/hr is to be stopped by applying brakes in the next 5 m. If the vehicle weighs 2000 kg, determine the average force that must be applied on it

Displacement, $x$ (in meters), of a body of mass $1$ kg as a function of time, $t$, on a horizontal smooth surface is given as $x = 2t^2$. The work done in the first one second by the external force is

The Work-Energy theorem states that the change in
