Question

define kinetic energy with explanation​

Answer 1

Answer:

In physics, the kinetic energy (KE) 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......

Answer 2

$\bold{\mathrm{\red{Kinetic\:Energy-}}}$

→Kinetic energy is the energy possesed by the particles of an object due to their movement or say motion.

${\underline{\boxed{\bf{KE=\dfrac{1}{2}m{v}^{2}}}}}$

→The kinetic energy of an object depends on both its mass and its speed.

→Kinetic energy is different from potential energy this is because KE is due to movement of particles, whereas PE is due to height basically.

→Unit of Kinetic Energy

•The SI unit of kinetic energy is Joule which is equal to 1 kg.m2.s-2.

•The CGS unit of kinetic energy is erg.
