Velocity of a Falling Object

Use this demonstration from the Wolfram Demonstrations Project to explore average and instantaneous velocity for a falling object. (To interact with it online you'll need to download and install Wolfram's free CDF Player.)

Introduction to Rectilinear Motion

Watch a particle moving along a line and figure out how to draw the corresponding position vs. time and velocity vs. time graphs. It is possible to change the position function by typing "s(x) = " followed by whatever function you'd like in the input line. (You can also access this applet on GeoGebraTube.)

Vertical Motion Simulation

This GeoGebra applet by Linda Fahlberg-Stojanovska simulates the motion of a projectile fired either straight up or straight down on Earth in the absence of air resistance. The user sets the initial height and the initial velocity and indicates whether units of measure should be feet or meters. You see the motion of the ball along the vertical axis, while the height as a function of time is plotted for you.
