Answer:
Because of motion an object has kinetic energy.
Step-by-step explanation:
Kinetic energy:
The energy of an object during its motion is called kinetic energy.
When we exert a force on the object inorder to accelerate it the work is done. During this work energy is transferred and object is moving. The energy is thus called kinetic energy.
Formula:
K.E = 1/2 mv²
Chemical energy:
Chemical energy in the amount of energy which is released during the chemical reaction. For example when a coal is burn the chemical energy is release in the form of heat and the amount of energy released is depend upon the amount of reactant.
Gravitational energy:
It is define as the energy of object in relation with another object because of gravity. it is also called as gravitational potential energy.
For example:
The pen which is placed above the table has more gravitational potential energy as compared to the pen which on the ground.
Potential energy:
It is the energy of an object because of its position in relation with other object. In simple words it is the form of energy of an object due to its position.
Formula:
P.E = mgh
