Question

What is the kinetic energy of an object?

Answer 1

Determine the kinetic energy of an object.

• The object's kinetic energy is the amount of work it can accomplish due to its mobility.
• It's a scalar quantity.
• It's entirely characterized by magnitude alone.
• The SI unit of kinetic energy is the Joule, which is equal to $1\frac{kg.m^2}{s^2}$.
• A CGS unit of kinetic energy is the erg.

$\Rightarrow K.E=\frac{1}{2}m{v}^2$

where,

• K.E= kinetic energy
• m = Body Mass
• v = Body Velocity

Hence, kinetic energy is defined as the energy an object has as a result of its motion.
