Describe the energy changes in the 4 stages of a bungee jump - at the top, in freefall, when the cord is stretching and at the bottom

There are 3 forms of energy during a bungee jump, kinetic (KE = 0.5mv^2), gravitational potential (GPE = mgh) and elastic potential (EPE = 0.5kx^2). Energy is conserved throughout, and it's assumed none i...

With the help of a suitably labelled graph, explain what is meant by resonance of a mechanical system.

The resonance of a system occurs when the driving force is equal to the natural frequency. - This occurs at a certain specific frequency. - For example: someone being pushed on a swing. - (Diagram o...

Explain the findings from Rutherford's alpha particle scattering experiment.

Rutherford's alpha scattering experiment showed that the majority of alpha particles fired at a thin sheet of gold leaf passed straight through. Some of the particles passed through the leaf with a small ...

Define the term "Gravitational Potential" and write down a formula which defines it.

The Gravitational Potential is the work done in moving a unit mass (1kg) from an infinite distance to a point in a radial gravitational field. The Gravitational Potential is defined as being zero an infin...

How can I measure the orbital period of a satellite around Earth?

In order to find the orbital period of a satellite around earth, you must understand the forces at play in this situation. You must equate the two radial forces acting on the satellite - these are Newton'...
