Given two events, (x1, t1) and (x2, t2), use a spacetimediagram to fi nd the speed of a frame of reference inwhich the two events occur simultaneously. What valuesmay s2 have in this case?
Notes Week 1 Physics Modules 1.1-2.1 1.1 The Nature of Physics Physics is not just a collection of facts and principles, but it’s the process by which we understand the Universe. Is a theory ever concrete and unchangeable No, theories are subject to change according to observations. 1.2 Solving Physics Problems The way physics is set up, we need to be able to learn problem-solving strategies. I SEE Identify, set up, execute, and evaluate. a. Identify i. Identify the target variables of the problem (the quantities you want to find) b. Set Up i. Set up the problem, choose the appropriate equations and decide if you are going to need them. Sketch a graph if you need to. ii. Esti
