LAUFER | AP PHYSICS 1 4 1.1 Intro to Kinematics Motion with constant velocity.  Motion occurs whenever an object changes position.  Kinematics is focused with looking at how vector and scalar quantities change while a particle is in motion. Understanding the difference between scalar (distance, speed, etc.) and vector (displacement, velocity, acceleration, etc.) quantities is key to kinematics.  Scalars are quantities that only have a magnitude assigned to them, while vectors have direction and magnitude. Displacement is a vector quantity and is given by ∆𝑥 = 𝑓𝑖𝑛𝑎𝑙 𝑝𝑜𝑠𝑖𝑡𝑖𝑜𝑛 − 𝑖𝑛𝑖𝑡𝑖𝑎𝑙 𝑝𝑜𝑠𝑖𝑡𝑖𝑜𝑛, while distance is simply the length of the path traveled. *For example, suppose a person goes from point A to point C, then to...
