PHYS 101 Lecture Notes - Lecture 2: Minor Places In Arda, European Route E20, Two Seconds
Document Summary
After studying this chapter, you should be able to use the following concepts and equations to solve kinematical problems. ) = [v1+v2]/2 (note: this is true only if the particle undergoes constant acceleration ) Average velocity (symbols in bold type are vectors. In one dimension, you can omit the vector notation since the information about a vector"s direction can be provided by a or a + sign. This will not work in two or three dimensions. ) V2 = v1 +at x2 = x1 +v1t +at2/2. [a]. subscripts 1 and 2 refer, respectively, to the initial and final values of various quantities. [b] the relative signs ( -, +) are very important. ) Most of what engineers and scientists study is change, more precisely how systems respond to a variety of external stimuli. Without change life would not be very interesting, actually there would be no life. In this chapter we study the simplest kind of changes.
