Learning Targets
Students should understand the general relationships among position, velocity, and acceleration for the motion of a particle along a straight line, so that:
(1) Given a graph of one of the kinematic quantities, position, velocity, or acceleration, as a function of time, they can recognize in what time intervals the other two are positive, negative, or zero, and can identify or sketch a graph of each as a function of time.
Students should understand the special case of motion with constant acceleration, so they can:
(2) Write down expressions for velocity and position as functions of time, and identify or sketch graphs of these quantities.
(3) Use the equations v = vo + at, x = xo + vot + ½ at2, and v2 = vo2 + 2a(x-xo) to solve problems involving one-dimensional motion with constant acceleration.
