Explain the following terms
1 Energy
2. Magnetic energy
3. Sound energy
4. Work
5. Chemical energy
Answers
Answer:
1) Energy Energy is defined as the ability to do work. Energy can be found in many things and can take different forms. For example, kinetic energy is the energy of motion, and potential energy is energy due to an object's position or structure. Energy is never lost, but it can be converted from one form to another.
2) Magnetic energy Each magnetic field contains energy, also called magnetic energy. She is a constant in physics. Because a magnetic field is generated by electric currents, the magnetic energy is an energy form of moving charge carriers (electrons).

4) Work Work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. ... If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.
5) Chemical energy Chemical energy, Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic. ... The chemical energy in food is converted by the body into mechanical energy and heat.

Answer:
1)energy, in physics, the capacity for doing work. It may exist in potential, kineticw, 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. ... For example, any given body has kinetic energy if it is in motion
2)The formula for the energy stored in a magnetic field is E = 1/2 LI2. The energy stored in a magnetic field is equal to the work needed to produce a current through the inductor. Energy is stored in a magnetic field. Energy density can be written as uB=B22μ u B = B 2 2 μ .
3)In physics, sound energy is a form of energy that can be heard by living beings. Only those waves that have a frequency of 16 Hz to 20 kHz are audible to humans. However, this range is an average and will slightly change from individual to individual.
4)Work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. ... To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd.
5)Chemical energy is energy stored in the bonds of chemical compounds, like atoms and molecules. This energy is released when a chemical reaction takes place. Usually, once chemical energy has been released from a substance, that substance is transformed into a completely new substance.
