Introduction to Physics

The natural science studying matter, motion, energy, and force.

Classical physics includes fields developed before the 20th century, like mechanics and electromagnetism.

Modern physics includes fields developed during the 20th century and beyond, like quantum mechanics and relativity.

A scalar quantity representing an object's capacity to do work, existing in forms like kinetic and potential.

An interaction that, when unopposed, changes an object's motion, causing acceleration.

The study of energy transfer and transformations involving heat and other forms of energy.

A disturbance that transfers energy through space and time.

A method using observation, hypothesis, prediction, experimentation, analysis, and conclusion to test theories.

The study of motion and forces, including statics, kinematics, and dynamics.

The study of the relationship between electric and magnetic phenomena.
