Dynamics
Your previous labs explored the concepts associated with our descriptions of motion. This is called kinematics. This lab will explore the causes of motion. This is called dynamics. Newton showed that changes in motion (defined as acceleration) are the result of the action of forces. If the mass of an object is held constant, then the acceleration is proportional to the force. If the force is held constant, the acceleration is inversely proportional to the mass. Mathematically, this is expressed as
