帮忙翻译下两段英语短文

Scientists consider energy to exist in several main forms. These include heat energy, which can raise the temperature of matter, electrical energy, which enables charge to flow around a circuit, and chemical energy, contained in fuels. The Sun converts nuclear energy into light, heat, ultraviolet radiation, and other forms of energy as electromagnetic waves.

Several types of energy:

Sound energy

Light energy

Nuclear energy

Heat energy

Electrical energy

Chemical energy

Kinetic and potential energy

Most of these energy types can switch from one form to anther.

 

 

Distance and displacement are two quantities which may seem to mean the same thing, yet have distinctly different definitions and meanings.

Distance is a scalar quantity which refers to “how much ground an object has covered” during its motion.

Displacement is a vector quantity which refers to” how far out of place an object is.” It is the object’s change in position.
