An object is thrown from the top of a 100 ft high building with an initial vertical velocity of 60 ft/s (in the upward direction). Gravitational acceleration is a constant -32 ft/s².

Click the "play" icon to see the object in motion. Click the check boxes to see the graphs of height, velocity, and acceleration. Notice the relationships between these three functions. For example, the object reaches its maximum height at the exact moment the velocity is zero. Notice also that the derivative of a quadratic function (height) is a linear function (velocity), and the deritative of a linear function (velocity) is a constant function (gravitational acceleration).
