Give one example of a body that has potential energy, in each of the following :
(a) due to its position at a height,
(b) due to its elongated stretched state.
Give one example of a body that has potential energy, in each of the following :
(a) due to its position at a height,
(b) due to its elongated stretched state.
(a) P.E. due to its position at a height :
Water at a height has P.E. stored in it. Falling water from a height can be used to do work like turning a wheel,
Also, The more height from where you drop the object the more damage it causes, This means the more potential energy it stores.
(b) P.E. due to its elongated stretched state :
A stretched rubber band (elongated state) has potential energy. The deformation occurred in the body can be utilized in storing potential energy (ex : spring , clay etc.) It does work in restoring itself to its original state. A pebble placed on the stretched rubber catapult, is thrown away when it is released to restore its original state.
In above situation we can use conservation of energy.
As we know, TE = KE+PE
