Solving physics problems: Motion of a 2D spring
In this video, we’ll break down how to solve physics problems involving the motion of a 2D spring. Learn about the forces at play, how to model the spring’s movement, and the key concepts behind ...
Regular OSCILLATION, for instance, by a particle in a solid, fluid or gas, displaced from its normal position or random motion, when the force required is proportional to the displacement. This motion ...
A plucked guitar string can vibrate for seconds before falling silent. A playground swing, emptied of its passenger, will gradually come to rest. These are what physicists call "damped harmonic ...
High harmonic emission occurs when an electron, liberated from a molecule by an incident intense laser field, gains energy from the field and recombines with the parent molecular ion. The emission ...
