Question

What is kinetic energy ?​

Answer 1

$\huge{\colorbox{red}{\color{black}{Answer}}}$

Simple Definition:

• The energy possess by a body due to its motion.

Detail Defination:

•  It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. 

Formula:

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

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

Answer 2

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Good afternoon kittu :)
