Rocket Launch Physics Explained

How do Newton’s Laws apply to a rocket launch? Using data from a simulation by Robert A. Braeunig, I present graphs of various measurements to explain Newton’s in the context of the multistage rocket Saturn V. In particular I explain how the g forces change for the astronauts as they ascend into orbit.   For those doing the NSW HSC, this video address the following dot point (though I do not specifically address LCM) analyse the changing acceleration of a rocket during launch in terms of the: – Law of Conservation of Momentum – forces experienced by astronauts  

Orbital Velocity Explained

In this video I discuss the connection between gravity and circular motion, involving satellites. I thus derive the formula used for orbital velocity of a satellite moving in a circular path   For those doing the HSC Physics course, this video addresses the following dot points • analyse the forces involved in uniform circular motion for a range of objects, including satellites orbiting the Earth • define the term orbital velocity and the quantitative and qualitative relationship between orbital velocity,the gravitational constant, mass of the central body, mass of the satellite and the radius of the orbit using Kepler’s Law…

how speaker works

A short video that explains the physics of a speaker. This video covers the dot point (in the NSW physics syllabus) • identify data sources, gather and process information to qualitatively describe the application of the motor effect in: the loudspeaker
