Chesta Pawan Manchanda 7 years, 5 months ago

Forces that store energy are called conservative force and those forces that do not store energy are called non conservative force . Conservative forces are against gravity and non conservative forces are friction. e.g you lift a book it is against gravity and you push a book it is friction.

Hook’s Law=According to this Law, the force needed to change the shape of spring is proportional to the displacement of the spring. The displacement referred here is how far the spring is compressed or stretched from its normal shape. Mathematically, Hook’s Law can be summarised as F= – k x.
