Question

what do you understand by kinetic energy? write its formula​

Answer 1

${ \huge \bf{ \mid{ \overline{ \underline{Answer}}} \mid}}$

The kinetic energy is equal to 1/2 the product of the mass and the square of the speed. In formula form: where is the mass and is the speed (or the velocity) of the body. In SI units, mass is measured in kilograms, speed in metres per second, and the resulting kinetic energy is in joules.

Answer 2

Explanation:

Kinetic Energy is the energy of motion, observable as the movement of an object, particle, or set of particles.

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity:

K.E. = 1/2 m v^2.

If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

• Unit of k. E. =joule (because it's a type of energy)
