The Energy Forms Quiz

Energy Fundamentals

• Energy is defined as the ability or capacity to do work.

Thermal Energy

• The unit of thermal energy is the joule (J).

Temperature

• Temperature is a measurement of the average kinetic energy of particles in a substance.

Energy Forms

• Vibrational energy is associated with the vibration or disturbance of matter.

Gravitational Potential Energy

• Energy stored by objects that are above Earth's surface is called gravitational potential energy.

Law of Conservation of Energy

• The law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another.

Radiant Energy

• Radiant energy from the sun is a form of electromagnetic radiation, including light and heat.

Nuclear Energy

• Energy released from the fusion or fission of the nucleus of an atom is called nuclear energy.

Elastic Potential Energy

• The energy stored by something that can stretch or compress is called elastic potential energy.

Energy Conservation Principle

• The energy of a system and its surroundings are interconnected, with energy being converted from one to the other.
• A 'system' refers to a region where energy is being transformed or converted.
• The 'surroundings' refer to everything outside the system that is affected by the energy transformations.
• Energy can be converted from one form to another, but the total energy remains constant.
• An example of energy conversion is in a power plant, where chemical energy is converted into electrical energy.
• When an explosive detonates, chemical potential energy is converted into kinetic energy, heat, and light.
• The total energy of the universe is constant, according to the principle of energy conservation.
• The principle that states there is a fixed amount of energy in the universe is known as the law of conservation of energy.
• In the context of energy conservation, energy is defined as the ability or capacity to do work.
