# 2: Model 1 - The One-Dimensional, Constant-Force, Particle Model


• 2.0: Introduction
• 2.1: Model Specifics
• 2.2: Kinematics
• 2.3: Dynamics
Dynamics is the study of the cause of motion, or more precisely the cause of changes in motion. In the late 1600’s Isaac Newton hypothesized that motion does not require a cause, rather changes in motion require causes. An object experiences a change in motion only when it interacts with some aspect of its surroundings. This is summarized by the idea that an object will maintain its state of motion, whether at rest or traveling at high speed, unless acted upon by some aspect of its surroundings.
