The photoelectric effect is the emission/removal of electrons, normally, from the surface of a metal. This is done as light is shone on the metal. This is a very useful proof that light can act as a parti...
The photoelectric effect is the emission of electrons from a metal surface when light is incident on it. When a photon (a light particle) hits the metal surface, it interacts with the metal's electrons. T...
(Many students have an intuitive understanding of the photoelectric effect and how it demonstrates quantisation, but it is important when preparing for an exam to be able to explain this clearly and preci...
While conceptually simple, drawing on understanding of kinematic equations and vectors, these projectile problems require attention to the details of the problem such as accounting for the launch height a...
When the skydiver jumps out, they are instantaneously at free fall (accelerate at 9.81 m/s). After this, a drag force from the displacement of air is felt. The drag force is proportional to the velocity s...
