answer must be big​

Answer 1

Answer:

Kinetic energy means

Explanation:

what is meant by kinetic energy

Pls follow

Kinetic energy, form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

Answer 2

$\huge \bf{ \pmb{ \blue{KINETIC} \: \red{ENERGY}}}$

✦ Kinetic Energy is the energy possessed by a body by virtue of its motion.

✦ It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.

FORMULA :-

• $\boxed{ \large \cal{ \pmb{ \: \: \: \orange{K.E. = \frac{1}{2} \: mv²}}}}$

Here,

K.E is the kinetic energy of the body

• "m" is the mass of the body
• "v" is the velocity.
