Kinetic energy is a form of energy that results from an object's motion. There are many types of motion that use kinetic energy: translation (moving from one place to another), rotation, and vibration. The measurement of kinetic energy in an object is calculated based on the object's mass and velocity. It is measured in Joules.
Examples of Kinetic Energy:
1. An airplane has a large amount of kinetic energy in flight due to its large mass and fast velocity.
2. A baseball thrown by a pitcher, although having a small mass, can have a large amount of kinetic energy due to its fast velocity.
3. A downhill skier traveling down a hill has a large amount of kinetic energy because of their mass and high velocity.
Potential energy is a form of energy that results from an object's position or arrangement of parts. It is stored energy that can become kinetic energy. It includes potential electrical, chemical, and nuclear energy. The measurement of potential energy in an object is calculated based on the object's mass and its height or distance. It is measured in Joules.
Examples of Potential Energy:
1. A rock sitting at the edge of a cliff has potential energy. If the rock falls, the potential energy will be converted to kinetic energy.
2. Tree branches high up in a tree have potential energy because they can fall to the ground.

Answer :
Kinetic Energy : The energy of an object because of its motion is called its kinetic energy.
Let's see it in details ;
Consider a ball kept in contact with a block on a table [see the first picture]. The ball and the block stay at rest and no work is done by the ball on the block [see the 2nd picture]. Now suppose, the ball is separated from the block and is moved towards it with a speed v.
Also, suppose that The ball sticks to the block as it hits it. The ball pushes the block forward and the block is displaced. So, the moving ball can do work on the block whereas the same ball, when at rest, cannot do any work.
We conclude that a moving ball has more capacity to do work than an otherwise similar ball at rest. In other words, a body has more energy when it is moving than when it is at rest.
Therefore, the energy of an object because of its motion is called its kinetic energy.
Potential energy : The energy of an object because of its position or shape is called its potential energy.
