Kinetic Energy:
Kinetic energy is the energy an object possesses due to its motion. It is directly proportional to the mass of the object and the square of its velocity. The formula to calculate kinetic energy is KE = 0.5 * m * v^2, where m is the mass of the object and v is its velocity.
- Example: A moving car has kinetic energy. When a car is in motion, it possesses kinetic energy due to its velocity.
- Characteristics:
- Kinetic energy increases as the mass or velocity of an object increases.
- Kinetic energy is a scalar quantity and is always positive.
- Importance:
- Kinetic energy is essential in various fields such as physics, engineering, and sports.
- Understanding kinetic energy helps in designing efficient machines and predicting the behavior of moving objects.

Potential Energy:
Potential energy is the energy an object possesses due to its position or state. It is stored energy that can be converted into kinetic energy. The formula to calculate potential energy varies based on the type of potential energy, such as gravitational potential energy, elastic potential energy, or chemical potential energy.
- Example: An object held above the ground has gravitational potential energy. When the object is lifted to a certain height, it gains potential energy due to its position relative to the ground.
- Characteristics:
- Potential energy depends on factors like height, position, and elasticity of the object.
- Potential energy can be converted into kinetic energy and vice versa.
- Importance:
- Potential energy plays a crucial role in understanding the behavior of systems like pendulums, springs, and chemical reactions.
- Utilizing potential energy effectively can lead to the development of renewable energy sources and energy-efficient technologies.
