KEY CONCEPTS KINEMATICS 1. MOTION IN ONE DIMENSION Kinematics is the study of how objects move, and the formal description of that motion. Kinematics doesn?t concern the forces that cause the motion or the masses involved. Instead it addresses such questions as: How far does an object move? How long does it take? How fast is it moving? The relevant quantities in kinematics are displacement, time, velocity, and acceleration. Displacement is related to the distance an object moves, displacement measures the change in position and is written as ?x. Time is denoted either as t, a specific moment in time, or as ?t, the time interval over which some event occurs. Velocity refers to how fast an object is moving and in what direction. The magnitude of
