Question

State the mathematical expression for kinetic energy and potential energy .Two examples when an object possesboth types of energy

Answer 1

$\textsf{\huge{\underline{Mathematical expression}}}$

Kinetic energy :

m = mass

v = velocity

$\boxed{\mathsf{K=\frac{1}{2}mv^2}}$

Potential energy :

m = mass

g = acceleration due to gravity

h = height

$\boxed{\mathsf{U=mgh}}$

$\huge{\underline{\textsf{Examples}}}$

(i) When we throw any object upwards , there is both kinetic as well as potential energy.

(ii) A bird flying has both kinetic as well as potential energy

Hope it helps !
