Hello,

Kinetic energy is energy of mass in motion,in other words the energy an object possesses because of motion, if work is done on the object by applying net force, thereby transferring the energy, it speeds up resulting in increase of energy. Therefore, kinetic energy is property of an object in motion which is dependent both on the motion and mass. SI Unit of KE is Joules, examples are a bullet fired from a gun, a bicycle in motion, a baseball thrown by pitcher, asteroid falling towards earth has large KE etc.

Hello,
In physics kinetic energy of an object is the energy that it posses due to its motion.In simple words kinetic energy of an object is the energy it has because of its motion.Its examples in every day life - flying airplane
Moving car
Bullet from gun
Cycling
Rollercoaster
Walking and running etc...

• Formula :- 1/2 mv2 i.e half mv square
  
• It has unit kilograms meters  squared per second square.
  
• it is stored energy
  
• it decreases with increasing height and potential energy increses with increasing height.
