Unformatted text preview: 1 / 8 Physics 111 Lecture 2b Your education is ultimately the flavor left over after the facts, formulas and diagrams have been forgotten. Paul G. Hewitt Constant acceleration Constant a Kinematics Question Examples Practice problems 2 / 8 Kinematics is the study of motion The set of equations that describe the motion of an object are known as kinematics equations Motion on a straight line with constant acceleration: a = constant (1) An object starts with an initial velocity v at t = 0 and accelerates with a constant acceleration a From Eq. (1), we get our first kinematics equation: v = v + at (2) Constant acceleration Constant a Kinematics Question Examples Practice problems 3 / 8 Now lets take a look at the definition of v avg assuming a is constant and we start at t = 0 v avg = x x t (3) By looking at the graph (see the board): v avg = v + v 2 (4) By using Eqs. (2), (3) and (4), we get the second kinematics equation: x = x + v t + 1 2 at 2 (5) Constant acceleration...
