The literature was full of examples that said you can't do this." -- Spencer Silver on the work that led to the unique adhesives for 3M "Post-it" notepads. Chapter 1: Mechanics z Velocity and acceleration z Newton’s laws of motion z Forces & torques z Kinetic and potential energy z Linear motion z Gravitational forces 1.1 Vectors Vectors are commonly used in Physics and will be introduced in this course. 1.1.1 Definitions A vector quantity is a quantity that has both a magnitude and a direction . In contrast, a scalar quantity has magnitude only and no direction. Some examples: Vectors Scalars Displacement Distance Velocity Speed Acceleration mass Force Time 1
