Difference between Kinetic and Potential Energy

The ability to do work is called energy. This energy can be stored in various ways. Energy is one of the physical quantities relative to the mass of an object. A body’s ability to pull or pull gravity and other forces of nature determines what kind of energy it is.

When an object is at rest, it is called the potential energy of the body. In other cases, when an object is in motion, it is said to have kinetic energy.

Difference between Kinetic and Potential Energy

Potential energy tends to affect something within the environment as soon as it is converted into another form of energy. A rock resting on a cliff is said to be an example of a body with potential energy.

When a rock falls, it gains kinetic energy. The energy stored in the body due to height is called gravitational potential energy. Some objects, such as waterfalls, have both kinetic and potential energy.

The height of the waterfall is one of the criteria for potential energy, and the speed of water is the criterion for kinetic energy.

The quality of the body determines the type of energy it has. When an object moves, the potential energy is converted into kinetic energy. Unlike potential energy, kinetic energy can be transferred from one body to another through collisional processes.

What is Potential Energy?

Potential energy or PE as we can call it is the force possessed by an object due to its position in relation to another body. PE can also be energy in the body due to its internal attraction if there is any charge in the body. One common characteristic of PE is strong gravity.

The value of PE is based on body weight in this case. This energy is necessary to move the body against the gravity of the earth. It is a source of energy waiting to expand and return to its original position.

It also has great potential power. The term potential energy was first coined by the great physicist William Rankin in the 18th century. Potential energy is always determined by the position of the body and not by its kinematics.

Some of the main factors affecting PE are its weight, its thickness relative to other material, and the strength of its gravitational field. Imagine a book or a metal ball resting on a table at a height of 2 m from the ground.

If the same material were placed at a height of 10 m above the ground, the material at a higher altitude would have a higher PE than the material at a lower altitude. It is also called energy recovery because it somehow forces the material back to its original. energy state.

When an object is lifted off the ground, work is done against the force of gravity. Doing this work requires effort. When an object falls back to the ground, it gains energy from gravity.

When matter previously fell from rest and gained energy, PE is converted into another form of energy. We will talk about the other forms later.

Example
  • When wood logs burn, the chemical energy is converted into heat.
  • It is also the source of charge, electrostatic potential energy of matter and electrodynamic potential energy.
  • Inside the nucleus of an atom are particles. The particles inside also have energy, which is nuclear energy.

What is Kinetic Energy?

The word walk is of Greek origin. The Greek word kinesis means “to go.” The name was originally coined by William Thomson.

When something is at rest, it has Potential energy, as we saw earlier. But when the same thing starts moving, it releases kinetic energy.

PE is the energy absorbed by the body’s positional force, Kinetic energy (KE) is the energy absorbed by the moving force of the object In other words, the work required to accelerate a body from rest to the required speed is called kinetic energy of the object.

This also applies to mobile particles. A person throwing a ball, a car running, or a drop of water falling are all examples of objects with kinetic energy.

Kei rests on two sides of the body. One object has mass and the other is moving at speed. Speed is the more important of the two, and plays an important role in determining energy.

There are different types of KE as we saw in PE. Some of them are Radiological, Thermal, Sound, Electrical and Mechanical. If an object is not moving, it has Zero KE.

Difference between Kinetic and Potential Energy

Kinetic Energy Potential Energy
Kinetic energy is the kind of energy present in a body due to the property of its motion Potential Energy is the type of energy present in a body due to the property of its state
It can be easily transferred from one body to another t is not transferable
The determining factors for kinetic energy are Speed or velocity and mass Here, the determining factors are Height/ distance and mass
Flowing water is one of the examples of kinetic energy Water present at the top of a hill is an example of potential energy
