Introduction to Physics (25-26)

Physics is the branch of science that studies:

• Plants and animals in their natural environments

• Matter and energy, and how they interact in nature

• Atoms and molecules in chemical reactions

• The effects of diseases on living organisms

Mathematics is known as the __________ of physics because it describes physical phenomena with numbers, symbols, and equations.

• Language

• Foundation

• Mother

• Tool

Classical physics focuses on phenomena that can be:

• Observed and measured directly in everyday life

• Observed only through microscopes

• Related to atomic nuclei

• Described only by computer simulations

Modern physics studies phenomena that occur:

• Only at slow speeds

• Only in laboratories

• At atomic and cosmic scales

• Only within the human body
