A particle of mass \(100g\) is thrown vertically upwards with a speed of \(5\) \(m/s\). The work done by the force of gravity during the time the particle goes up is

The potential energy of a \(1\) \(kg\) particle free to move along the \(x\)-axis is given by \(V\left( x \right) = \left( {{{{x^4}} \over 4} - {{{x^2}} \over 2}} \right)J\).
The total mechanical energy of the particle is \(2J.\) Then, the ...

A ball of mass \(0.2\) \(kg\) is thrown vertically upwards by applying a force by hand. If the hand moves \(0.2\) \(m\) while applying the force and the ball goes upto \(2\) \(m\) height further, find the magnitude of the force. (consider $...
