Corkscrew rollercoaster closes
Corkscrew rollercoaster closes

Duration: 01:36

Britain's first double-looping rollercoaster at Alton Towers is closing after 28 years.

 
E=mc2
E=mc2

Duration: 00:37

An animated explanation of E=mc2.

 
Energy changes in the Big Contraption - an series of experiments
Energy changes in the Big Contraption - an series of experiments

Duration: 06:40

A series of experiments are linked together as part of the BBC series 'Bang Goes the Theory', providing students with an opportunity to identify different types of energy.

 
Energy efficiency in a leisure centre
Energy efficiency in a leisure centre

Duration: 03:10

An investigation into energy efficiency in a leisure centre.

 
Energy transfer
Energy transfer

Duration: 01:15

A demonstration of how energy, which cannot be created, is transferred from one place or object to another.

 
Heat energy and friction - meteors in the Earth's atmosphere
Heat energy and friction - meteors in the Earth's atmosphere

Duration: 01:19

A discussion about heat energy and friction using meteors as an example. When meteors enter the Earth's atmosphere they transfer kinetic energy to heat by friction.

 
Heat transfers
Heat transfers

Duration: 02:03

An introduction to the four methods of heat transfer – conduction, convection, radiation and evaporation. Animations of atoms are seen.

 
Heat transfers and the vacuum flask
Heat transfers and the vacuum flask

Duration: 01:49

Heat loss from liquids in a vacuum flask is explained. Conduction, convection, radiation and evaporation are mentioned.

 
Potential and kinetic energy
Potential and kinetic energy

Duration: 01:01

A demonstration of how energy is changed from potential to kinetic energy which is used to power a radio.

 
Racing cars harness energy from braking
Racing cars harness energy from braking

Duration: 02:44

A practical demonstration of how racing cars are able to harness energy from braking, known as regenerative braking.

 
Smoke rings
Smoke rings

Duration: 00:59

Simple equipment is used to show how blasts of air can transfer energy over long distances.

 
The conservation of energy
The conservation of energy

Duration: 03:19

A dramatic illustration of the 'principle of the conservation of energy' in which energy cannot be created or destroyed.

 
What energy changes happen during freezing?
What energy changes happen during freezing?

Duration: 02:31

The crystallisation of sodium acetate is used to demonstrate that freezing and crystallisation releases heat energy.

 
What is a horse power?
What is a horse power?

Duration: 03:21

The term 'horse power' is defined using the original method that James Watt used in the 18th century to help promote his new steam engine.

 
Work, energy and power (pt 1/2)
Work, energy and power (pt 1/2)

Duration: 00:18

A diver demonstrates energy conversion.

 
Work, energy and power (pt 2/2)
Work, energy and power (pt 2/2)

Duration: 00:45

An example of transferance of work done to kinetic energy using the example of a cyclist.
