In the instant when the DVD is dropped, it will have an acceleration of g, with no drag force acting on it as it is not moving. As the DVD accelerates downwards, the drag force acting on it increases and ...

We need to understand both what this question is asking of us, and what the question tells us. We are asked to investigate the motion of the parachutist, therefore in this case we need to apply Newton’s L...

A baryon is a particle that is made up of three quarks (which are fundamental particles) bound by the strong force. A meson, on the other hand, is a particle which is made up of one quark and one antiquar...

Temperature is a measure of the average kinetic energy of an object. We can approximate this average kinetic energy using the relationship E≈kT. Where k is the boltzmann constant and T is the absolute tem...
