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...
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....
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...
Aerodynamics – Professor Holger Babinsky – 105science
This week we find out about aerodynamics and what it involves. We meet Professor Holger Babinsky at Cambridge University Engineering Department. He talks about wind tunnels and the need for bumps on aeroplane wings. Listen to the...
