Mechanical Equivalent of Heat - Interactive 3D practical

This is a student or teacher controlled experiment that allows the equivalence of heat and mechanical energy to be determined. We generate the heat by the friction between a cord and a brass cylinder which is rotated under the user’s control.

The user controls the rotation whilst monitoring the temperature of the brass cylinder. The user is free to move anywhere within the laboratory in order to interact with the apparatus.

You can try one of the simulations from our website. Instructions are viewable within the simulation.

The simulation is perfect for demonstrating this experiment in front of the class but can also be used by students in a variety of ways:

• Directly to prepare for a laboratory experiment by familiarising them with the equipment to be used and the methodology of the experiment.

• As revision for an experiment that has previously been performed in the laboratory.

• For home-learning where there is no access to a laboratory.

• To make up for an experiment missed due to sickness.

• As a personal experience of an experiment normally only performed by the teacher in front of the class.

Downloads include: a PowerPoint giving full instructyons including a video, background on the Physics and the simulation application in a zip file.

The Virtual Physics Laboratory of which this simulation is a part, has the Association for Science Education’s Green Tick of Approval. More information can be found on our website.

I’ve found your software very useful when a concept comes up with pupils and I have to demonstrate something really quickly without having the time to set up a formal experiment for them. The graphics are great and I really like the ability to move around the classroom and observe the experiment from different aspects. I am far more likely to go to one of your interactive experiments if it’s demonstrating something that we don’t have equipment for.“

I thought that the controls were pretty easy to get used to and the detail in the apparatus was excellent being able to zoom in and see the set up of the multi-meter and read scales, being careful of parallax. This type of software is most useful in experiments which can’t be done in the lab like the gravity on the moon or where the equipment is too expensive or difficult to use like the Millikan Oil drop.
