Work Energy and Power

1. Introduction In physics, work is said to be done when a force applied to an object causes displacement in

The dimensional formula of work is \([ML^2T^{-2}]\). Its absolute unit in SI is joule and is denoted by \(J\). In

The energy of a body is defined as its capacity for doing work. Since, the energy of a body is

If a body has a mass of $ \displaystyle m$ then, $ \displaystyle \begin{array}{l}\text{K}\text{.E}\text{.}=\dfrac{1}{2}m{{v}^{2}}=\dfrac{1}{{2m}}{{m}^{2}}{{v}^{2}}\\\Rightarrow \text{K}\text{.E}\text{.}=\dfrac{{{{p}^{2}}}}{{2m}}\end{array}$ where $ \displaystyle p$ is

1. Introduction When two bodies collide, they deform momentarily and then regain their shapes. During this collision, a part of

Conservative forces A force is described as a conservative force if the work done by or against it when moving
