Question

Good morning friends
Give the expression of Kinetic
energy? and define kinetic energy?

Answer 1

hey mate....
good morning. have a nyc day...
kinetic energy is a form of energy which is due to motion of any objects......
hope its helps

Answer 2

$<b><i>$
Kinetic Energy is the Energy of Motion. An object that has motion -whether it is vertical or horizontal motion - has kinetic energy.

There are many forms of kinetic Energy
-Vibrational(The energy due to vibrational motion)
- Rotational (The energy due to rotational motion)
- Translational(The energy due motion from one location to another)

The amount of translational kinetic Energy that an object has depends upon two variable:
Mass(m) of the object and
velocity(v) of the object

Expression for Kinetic Energy :
$E_{k} = \frac{1}{2}mv^{2}$

This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed.
That means that for a k-fold increase in speed, the kinetic energy will increase by a factor of k.

$Is\: Kinetic\: Energy\: Scalar\: or\: Vector ?$
Kinetic energy is a scalar quantity, it does not have a direction. Unlike velocity, acceleration, force, and momentum, the kinetic energy of an object is completely described by magnitude alone.

$Units\: of\: Kinetic\: Energy$
Like work and potential energy, the standard metric unit of measurement for kinetic energy is the Joule.
