PHYS 1023 Lecture Notes - Lecture 1: Strong Interaction, Kilogram, Weak Interaction
Document Summary
Relies on finding a way to disprove the rules that we think we know. When we can"t disprove them, then we think we have learned something: to find something that breaks the rules that we think we already know. Our rules, after trying over and over to break them a theory. Aristotle; a force is necessary for all motion. Newton"s first law of motion is the law of inertia. Law of inertia for stationary objects: once an object is stationary it remains stationary it does not move when it is still. The fact that it does keep moving is called inertia. Law of inertia: stationary things continue to stay stationary. Moving things continue to move, unless something make them act differently. Velocity: it tells you how fast and what direction ex. An object at rest stays at rest, unless acted on by a net force.
