“Energy is an agent which is responsible to do work.” OR “The capacity or ability of doing some work is known as Energy.” There are different types of energy as described below:
Types of Energy
The energy due to motion of a body is called Kinetic Energy. Kinetic Energy is one of the types of energy.
If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed. The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.
For example Moving ball can break a glass window or A striking hammer can drive a nail.
The energy which is possessed by a body by means of its position is known as potential energy. or Potential energy is the stored energy of position possessed by an object.
“Energy of an object due to its motion or position is called Mechanical Energy.” OR “Mechanical Energy is a combination of kinetic and potential energy resulting from the force of gravity or the movement or release of a machine component, such as a spring, clamp, or wheel.”
Energy in a substance that can be released by a chemical For example: coal, petroleum are the source of Chemical Energy.
Energy is the ability to do work, where work is done when a force moves an object. We need and we use energy every day, and energy is available in all different forms. Electrical energy is energy that’s stored in charged particles within an electric field. Electric fields are simply areas surrounding a charged particle. In other words, charged particles create electric fields that exert force on other charged particles within the field. The electric field applies the force to the charged particle, causing it to move – in other words, to do work.
Heat or thermal energy:
Matter is made up of atoms and molecules (groupings of atoms) and energy causes the atoms and molecules to always be in motion – either bumping into each other or vibrating back and forth. The motion of atoms and molecules creates a form of energy called heat or thermal energy which is present in all matter.
Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power or hydropower. The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir.
Nuclear power is the use of nuclear reactions that release nuclear energy to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion.
Sound is the movement of energy through substances in longitudinal (compression/rarefaction) waves. Sound is produced when a force causes an object or substance to vibrate — the energy is transferred through the substance in a wave.
