Question

Write about energy..and it's types with examples.

Answer 1

$\huge\bigstar\underline\red{Energy}$

It is the capacity to do work. In other sense, we can say that, if any object works it has the energy.

___________________________

Types :

• Potential energy :

It is the amount of energy possessed by any object at the state of rest.

Example :

★Energy possessed by a streched spring of a toy.

★Energy of a standing bus.

So, anything which is at rest, can be said to have potential energy.

________________________________

• Kinetic energy :

It is the amount of energy, possessed by an object in the state of motion.

Example :

★Energy of flowing water.

★Energy of running player.

So, anything which is in the state of motion , can said to have Kinetic energy.

________________________________

• Mechanical energy :

Energy of any object is set mechanical if it possesses both potential and kinetic energy.

Example :

★Energy possessed by ceiling fan.

★Energy of running pumping machine.

Some other types of energy :

• Wind energy
• tidal energy
• solar energy
• Geothermal energy
• Electric energy
• Heat energy
• Sound energy
• Light energy

Answer 2

Answer:

Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. After it has been transferred, energy is always designated according to its nature. Hence, heat transferred may become thermal energy, while work done may manifest itself in the form of mechanical energy.

For example, any given body has kinetic energy if it is in motion. A tensioned device such as a bow or spring, though at rest, has the potential for creating motion; it contains potential energy because of its configuration. Similarly, nuclear energy is potential energy because it results from the configuration of subatomic particles in the nucleus of an atom.

Similarly, nuclear energy is potential energy because it results from the configuration of subatomic particles in the nucleus of an atom.Energy can be neither created nor destroyed but only changed from one form to another. This principle is known as the conservation of energy or the first law of thermodynamics. For example, when a box slides down a hill, the potential energy that the box has from being located high up on the slope is converted to kinetic energy, energy of motion. As the box slows to a stop through friction, the kinetic energy from the box’s motion is converted to thermal energy that heats the box and the slope.
