Confusing speed with velocity, neglecting the directional component of velocity. Overlooking that deceleration is still a form of acceleration (negative acceleration). Failing to correctly apply the vector …
Orbital Velocity: Why Mass Doesn't Matter • Physics Forums
Oct 10, 2015 · The discussion centers on the independence of orbital velocity from mass, specifically in the context of satellites. The centripetal force equation, m2v2/r = GM1m2/r2, illustrates that when …
What is the derivation for the drag force equation used in Terminal ...
Feb 17, 2005 · The drag force equation used in terminal velocity, expressed as F_drag = 1/2 * C_D * A * ρ * v^2, is fundamentally a definition rather than a derivation. The drag coefficient (C_D) is …
Why a force perpendicular to the velocity doesn't change the …
Jan 10, 2020 · Hence, if the force is perpendicular to the velocity, then , which means the kinetic energy of the particle is constant, hence the speed is constant. Sir but in this derivation we have used the …
