Question

define kinetic energy

Answer 1

$\huge {\mathfrak {\blue{\underbrace{ \overbrace{answer}}}}}$

Kinetic Energy Explanation

To accelerate an object we have to apply force. To apply force, we need to do work. When work is done on the object, energy is transferred and the object now moves with a new constant speed. The energy that is transferred is known as kinetic energy and it depends on the mass and speed achieved.

The definition of kinetic energy in Physics

“Kinetic Energy is the energy possessed by the body by virtue of its motion”

Kinetic energy is a scalar quantity. Kinetic energy is completely described by magnitude alone

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.
