What is potential energy?

Potential energy is the energy that an object possesses due to its position or condition, such as its height above the ground or its state of compression or stretching. This form of energy can be converted into other forms, such as kinetic energy, when the object moves or changes its position.

What is kinetic energy?

Kinetic energy is the energy possessed by an object due to its motion. It is calculated as half of the object's mass multiplied by the square of its velocity. The faster an object moves or the heavier it is, the greater its kinetic energy.

What is thermal energy?

Thermal energy is a form of kinetic energy that results from the motion of particles within a substance. It is a type of internal energy stored within a system that arises from the movement of atoms and molecules at the microscopic level. Increasing the thermal energy of a substance typically leads to a rise in its temperature, as the particles move faster and collide with each other more frequently.

What is electrical energy?

Electrical energy is the energy produced by the movement of electrically charged particles, typically electrons. It is a form of energy that powers various devices and systems by converting electricity into other forms of energy such as light, heat, or mechanical motion, providing the necessary power for numerous everyday applications.

What is light energy?

Light energy is a form of electromagnetic radiation that is visible to the human eye. It is produced by vibrating electric charges and travels in waves. Light energy is essential for vision, photosynthesis in plants, and various technological applications such as lighting and communication systems.

What is sound energy?

Sound energy is a form of energy produced by vibrations that travel through a medium, such as air or water. These vibrations create waves of pressure that our ears can pick up and interpret as sound. Sound energy is a type of mechanical energy and is measured in units called decibels. It is used for communication, music, and various technological applications.

What is chemical energy?

Chemical energy is a form of potential energy that is stored in the bonds of chemical compounds. It is released when a chemical reaction takes place, either through combustion, metabolism, or other chemical processes. This stored energy can be converted into other forms of energy such as thermal, mechanical, or electrical energy when the bonds are broken during a reaction.

What is nuclear energy?

Nuclear energy is the energy released during nuclear reactions. It is generated through processes such as nuclear fission or fusion, where atomic nuclei are split or combined, respectively, releasing a large amount of energy. Nuclear power plants use controlled nuclear reactions to produce heat, which is then converted into electricity.

What is mechanical energy?

Mechanical energy is the sum of potential energy and kinetic energy in an object. Potential energy is stored energy due to its position or state, while kinetic energy is the energy of motion. The total mechanical energy of an object remains constant as long as only conservative forces (such as gravity or spring forces) are acting on it, according to the law of conservation of energy.

What is renewable energy?

Renewable energy refers to sources of energy that are naturally replenished, such as sunlight, wind, and water. These sources are sustainable and environmentally friendly, as they produce minimal to no greenhouse gas emissions and contribute to reducing reliance on fossil fuels. Examples of renewable energy technologies include solar panels, wind turbines, hydroelectric power, and geothermal power.
