Uniform and Accelerated Motion

Linear, Quadratic and Periodic Functions

Instead of asking physics students to use "the equations of uniformly accelerated motion" only to solve single-answer problems, the Pointer Plane software easily allows them to design dynamic mathematical functions which cause a laser dot to move in various ways.

A simple task might be, "Move the dot smoothly from the rock to the figure in 10 seconds."

A more complex task involving uniformly accelerated motion can be, "Design one function, x = f(t), which makes the dot begin at the rock, move continuously to the figure in 10 seconds and then return to the rock.

As an example of simple harmonic motion, the task might be to make the dot oscillate smoothly between the rock and the figure once every 5 seconds.

The motions can be done on a small table by small groups, or they can be projected on the front of the room as a whole-class activity.
