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 ...
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...
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'...
Kepler's third law states that the square of the period of the orbit is directly proportional to the cube of the radius of the orbit (T^2=kr^3) where r is some constant to be determined. This can be deter...
Fermat's Principle states that light will always take the path of least travel TIME (NOT DISTANCE), at a first glance it appears that the path of least time would be a straight line from A to B, but this ...
