Physics of Bungee Jumper for A Level Physics

The Energy Transition Phases Assume the jumper of mass m starts from rest at height h. The bungee cord has a natural length L and a stiffness (spring constant) k. Phase A: The Freefall (0 < y  < L) Before the cord tightens, the jumper is in freefall. Forces: Only weight (mg) acts on the jumper (i…

GeoGebra Animations for Physics Teachers: Beats and Interference

The following animation is ideal for physics teachers to explain the phenomenon of interference when beats are formed by the combination of  two waves which have slightly different frequencies. You can see the individual waves as well as the resultant wave. Constructive and destructive interference …
