## Falling in a vacuum

Aristotle believed that heavier objects naturally fall faster than lighter objects. His theory was no doubt based on what he observed. But he was not able to observe objects falling in a near-vacuum. Below are videos that show just this, … Continue reading

## Polynomial Calculus

Polynomial calculus introduces the concepts of differentiation and integration through algebraic and geometric arguments. The rationale is that the notion of limits and differentials are not needed at the outset to illuminate the ideas. From the introduction to the Polynomial … Continue reading

## Spring energy

Springs can be stretched or compressed, and when this happens, they have potential energy. That energy is transformed into kinetic energy as the spring returns to its rest position. This lab allows students to observe a moving object encounter a … Continue reading

## Ramp Slide

This lab can be used to observe the behavior of a brick sliding down a ramp. This complements the study of free body diagrams.

## Ramp Jump

This lab can be used to investigate the relationship between velocity and the height above ground. We use it when studying potential and kinetic energy.

## Roller Coaster with Velocity

This lab can be used to investigate the relationship between velocity and the height above ground. We use it when studying potential and kinetic energy.

## Acceleration and Time Lab

The Velocity and Time Lab allows gathering velocity and time data that students can use to determine average acceleration, and estimate instantaneous acceleration using slopes of the graph. They can also estimate how far the cars have traveled by finding … Continue reading

## Velocity and time lab

The Position and Time Lab allows gathering position and time data that students can use to determine average speed, and estimate instantaneous speed using slopes of the graph. In this lab, we will work the opposite direction. We have only … Continue reading
