# Dynamics

KidzSearch Safe Wikipedia for Kids.

**Dynamics** is the study of forces and their effects on motion over time. It is a branch of classical mechanics.

Isaac Newton developed three laws of motion that are fundamental to dynamics.

Some people consider dynamics to be made up of kinematics and kinetics.^{[1]} Others consider dynamics and kinematics to be separate, and do not use the word kinetics.^{[2]} Under the second view, kinematics is about describing how a system is at the moment, and dynamics is about how and why the system changes with time.^{[3]}
