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...

when do plants grow

It’s not easy to measure how fast a plant grows. You would probably not be too keen to take measurements every few hours – and especially not overnight. There are ways, however, of seeing...

monitor breathing

Is your breathing steady while you sit restfully? How does it change when you talk? How does it change when you exercise? How quickly do you recover after exercise? To find out you can...

effect of surface area on a rate of reaction

Hydrochloric acid and marble (CaCO3) react to form carbon dioxide gas. The gas can be captured and measured using a gas syringe. A position sensor can be attached to the syringe to record the...

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...

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...

position or angle sensor

This sensor allows superb and easy to do investigations into the swing of a pendulum leading on to studies of harmonic motion and damping. (See several examples nearby). It allows you to record the...
