Answer:
The kinetic energy of an object is the energy that it possesses due to its motion. Kinetic energy definition is given as:
The energy of an object because of its motion or the energy gained by an object from its state of rest to motion.
Following is the formula of kinetic energy:
KE=12mv2
Where,
- KE is the kinetic energy of the object
- m is the mass of an object
- v is the velocity of an object
Kinetic energy is an example of scalar quantity which means that the quantity has only magnitude and no direction.
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 of Kinetic Energy
- A semi-truck travelling 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 certain speed comprises kinetic energy as water has certain velocity and mass.
- The kinetic energy of an asteroid falling towards earth is very large.
- The kinetic energy of the aeroplane is more during the flight due to large mass and speedy velocity.
