Simple to set up and highly effective, the coupled pendulums transfer energy one to the other thanks to a thin string that couples them. This system allows teachers to introduce the normal modes of oscillation. The resultant motion corresponds to the composition of two oscillations: the centre of mass motion and the relative motion of the pendulums. COMPONENTS : • Threatened rod (2x) • Sphere with Hook (2x) • Polyester inelastic Cord. LAWS & PRINCIPLES INVETIGATED : • Pendulums • Energy transfer • Harmonic motion • Couplement • Resonance
Crooke’s Radiometer
Specifications : Size: 10 x 15 cm (dia. x height) – Weight: approx. 250 g – Mounted on base. Investigating the energy and impulse of an electromagnetic wave. Invented by Sir William Crooke, the vanes in the highly effective radiometer rotate when exposed to solar radiation. The cause for this rotation can open up much debate for which students should be encouraged to develop their own explanations. Some will state that the device relies upon the difference in absorption of impulse between the black and metal vanes. Others may think there is a difference in temperature of the vanes. This device has been designed with black vanes that absorb electromagnetic radiation and reflective metal vanes. Students need also remember that black painted sides getwarmer than metallic ones. LAWS & PRINCIPLES INVESTIGATED : • Energy conversion.
