An overhead tank having some water possesses .......... energy.

Law of conservation of energy states that:

Energy possessed by a body by virtue of its motion is :

A student sitting at the top of a tree has ............ than the student who is sitting on the ground.

The form of energy present in a wound spring is:

The energy directly related to the speed of a moving body and its mass is:

A boy holds a pendulum in his hand while standing at the edge of a circular platform of radius $$r$$ rotating at an angular speed $$\omega$$. The pendulum will hang at an angle $$\theta$$ with the verticle such that

A particle of mass $$'m'$$ describes a circle of radius $$(r)$$. The centripetal acceleration of the particle is $$\displaystyle\frac{4}{r^2}$$. The momentum of the particle:

A mass tied to a string moves in a vertical circle with a uniform speed of $$5\;m/s$$ as shown. At the point $$P$$ the string breaks. The mass will reach a height above $$P$$ of nearly: $$(g=10\ m/s^{2})$$
