 # Give Few Examples Of Kinetic Energy

Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles.

### Definition

The kinetic energy of an object is the measure of the work an object can do by virtue of its motion. Kinetic energy is a scalar quantity, and it is entirely described by magnitude alone.

The Formula for Kinetic Energy
KE=1/2 mv2

Where KE is the kinetic energy,

m is the body’s mass

v is the body’s velocity.

### 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.

### Examples

Some examples of Kinetic Energy are:

• A truck moving down the road has more kinetic energy than a car travelling at the same speed because the truck’s mass is much more than the car’s.
• A river flowing at a definite speed comprises kinetic energy as water has certain velocity and mass.
• As the heating components inside the toaster get more heated, they emit radiant energy that heats and toasts the bread.
• A bullet flying through the air is literally moving. This energy is then transferred to the object the bullet hits in the form of damage. (14) (0)
