Beginner's Guide to Physics

Magnets are objects that produce an invisible field of forces called a magnetic field. This field affects all magnetic objects and materials within it. Magnetism is created by the movement of electric charges. Find out more in Magnetism, a title in The Beginner's Guide to Physics.

Thermodynamics explains how energy moves and transforms. It is the science of the relationship between heat, work, temperature, and energy. The forces of thermodynamics are on display everywhere. Find out more in Thermodynamics, a title in The Beginner's Guide to Physics.

Everything people can see and touch is an example of matter. The three states of matter most often observed are solids, liquids, and gases. Matter can change from one state to another when the temperature is raised or lowered. Find out more in Properties of Matter, a title in The Beginner's Guide to Physics.

Force refers to the action of pushing or pulling something. Forces can cause objects to move, face a different direction, or change shape. An object's change in position is called motion. Find out more in Forces and Motion, a title in The Beginner's Guide to Physics.

All waves are disturbances that transfer energy. When waves move through matter, their energy is passed along from molecule to molecule. However, the matter itself does not actually move forward. Find out more in Waves, a title in The Beginner's Guide to Physics.
