I
believe physics describes how matter and energy and how they are related.
Matter is said to be what makes up objects. Energy comes in many forms, such as
light, sound, and heat. Physics is also used to learn about nature and how the
universe works.
Physics is different than other sciences, such as biology and chemistry.
Biology explains life. It talks about the millions of cells that make up
organisms. Chemistry deals with atoms and molecules. Physics is different
because it talks about matter, energy, and force and how they work in real
life.
