Difference between electrical and mechanical energy?

Answer 1

Light travels exclusively through space or along optical fibres by the mechanism of electromagnetic propagation. Electrical energy can also do that, in which case it is called microwave radiation or radio waves, but it can also be carried on wires.

Answer 2

Electrical engineering specializes in generating power and electric signals anywhere, whereas mechanical engineers specializes in mechanical structure, engines, fuel power, joints etc. Usually one can't function without the other, unless you study both.

Answer 3

The relation between power and energy is simply that power is the rate of energy flow. This applies to any sort of energy, whether electrical, mechanical, or other, In electrical engineering, power is in units of Watts, or multiples of Watts, which represents the flow of electrical current times the potential difference in the circuit, thus power (Watts) = Volts x Amps. Note that 1 Watt = 1 Joule per second (this applies to any type of energy flow). Therefore electrical energy can be expressed in Joules, ie power (Watts) = energy (Joules) per second. However in electrical work we measure volts and amps normally, so this gives power in Watts directly. Energy is usually quoted as a multiple of power x time, so we talk of kilowatthours for example, this is a unit of energy, not power.

Answer 4

Only that work is done against different types of forces - for potential mechanical energy, against forces that act on a larger scale, such as the elastic forces in a spring, or the gravitational force; in the case of chemical energy, electric forces at the level of individual atoms.

Answer 5

the difference between chemistry and electricity it that one is the reaction of matter, and the other is the charge of matter.

Answer 6

I think chemical energy is gases or liquids that burn while electrical energy is friction.

Answer 7

Chemical energy is enery stored in chemical bounds that is released when the bonds are broken.

Kinetic energy is the energy a moving object has.

Answer 8

Mechanical energy is combination of potential and kinetic energy. Chemical energy is stored in an object.
