PHYS 1010 Notes Week 2 Jan 2022 Vectors and Coordinate Systems Motion Mechanics: the general term for the branch of physics which deals with the motion of objects, and the forces that cause motion Kinematics: basic principles of how an object moves without taking forces into consideration Motion: the change of an object's position within some time Galileo Developed foundation for describing physical motion Relationships between four physical properties: time, position, velocity, and acceleration Position and time Measure position by placing an arbitrary coordinate system (reference point) around the object and describing the position as an (x, y) coordinate C
