Mr.Rockensies Regents Physics Kinematics Mr.Rockensies Regents Physics
What is Kinematics? study of motion: a branch of physics that deals with the motion of a body or system without reference to force and mass Variables involved: displacement (d), velocity (v), acceleration (a), time (t)
Formulas for linear motion with constant acceleration Vf = vi + at v = (vi + vf)/2 d = vit + (½)at2 vf2 = vi2 + 2ad
Steps for Problem Solving Identify all info given in the problem Identify the unknown Find the appropriate formula Plug in values and solve.
