• Slip Angle

The main problem in measuring slip angle is that it is a very small angle. A change of 0.5° is already significant. Slip angle also varies quickly, so fast changes (above 1Hz) are significant. There are two main ways to measure slip angle of a tire: on a vehicle as it moves, or on a dedicated testing device.

• Rutherford Scattering

Evidence for Nuclear Interaction. Rutherford and colleagues were able to calculate the number of alpha particles which would be scattered into any angle based upon the number of nuclei and their spacing in the gold foil.

• Physics Tutorial: The Law of Reflection

Light is known to behave in a very predictable manner. If a ray of light could be observed approaching and reflecting off of a flat mirror, then the behavior of the light as it reflects would follow a predictable law known as the law of reflection. The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
