Question

define kinetic energy.......​

Answer 1

$\rightarrow\huge\text{Answer}$

☛ Define kinetic energy

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.

☛What are some examples of kinetic energy?

when you are walking or running your body is exhibiting kinetic energy. A bicycle or skateboard in motion possesses kinetic energy. Running water has kinetic energy and it is used to run water mills.

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.
