experiments

pendulum & simple harmonic motion

A position sensor can be used to study this. The sensor is attached to a weight and spring assembly as shown. This can also be used to study the effects of changing the mass...

handling data

cart rolling down a slope

A cart rolling down a hill certainly has energy which in turn affects its speed. But how does this speed change when you start the car off from a different point on the hill....

handling data

pendulum swings or bobbing masses

We used a turn (or position) sensor connected to the computer and recorded the swings of a pendulum made of a metal rod and a weight. We tried again this time connecting the sensor...

a device for teaching dynamics: Dynakar (2013)

It’s a good sign when you find a simple device to help teach a complicated idea. The DynaKar, invented by ScienceScope, is an example of that and it was a finalist for a BETT...

simple harmonic motion

Simple harmonic motion is rarely as simple as the lesson title implies. This potentiometer-based sensor measures angles as its core rotates. Attaching a ruler as shown (or hack saw blade) gives to a near-perfect...

light gates and switches

These are digital switches that record a time when triggered by say, a dynamics trolley or a card. When you enter parameters like distance or mass into the software, velocity, acceleration or momentum are...
