Definition:Kinetic Energy

Definition

Let $B$ be a body.

The kinetic energy of $B$ is defined as the energy appertaining to $B$ due to its motion.

It is a scalar quantity.

Symbol

$T$

The symbol used to denote kinetic energy is often $T$.

Its $\LaTeX$ code is T .

Examples

$1 \ \mathrm {kg}$ moving at $1 \ \mathrm m \, \mathrm s^{-1}$

A body of mass $1 \ \mathrm {kg}$ moving at $1 \ \mathrm m \, \mathrm s^{-1}$ has a kinetic energy of $\dfrac 1 2$ a joule.
