A quick search revealed that Seth (nature bats last), whose knowledge of
physics is much greater than mine, had his own experiences with duke's
But how can a mechanical engineer not know anything about mechanics?
So tell us again. How does a satellite in stable velocity in earth orbit have
acceleration or deceleration???????????????
Gravitation acts as the centripetal force and Newton's laws apply. Newton's
laws *always* apply to macroscopic situations, duke, you fucking moron.
F=ma is one of Newton's laws. The centripetal force (gravity) causes a
centripetal acceleration of the mass. Because a centripetal acceleration
acts perpendicularly to the direction of motion, it changes the mass's
direction rather than its speed.
Acceleration is defined as the rate of change of velocity with respect to
time, a = dv/dt. velocity is defined as the rate of change of displacement
with respect to time, v=dx/dt.
Got it, duke? Speed is not velocity. The satellite's change of displacement
is zero during the course of one revolution.
You know no mechanics and hence cannot possibly be a mechanical engineer.
You pretended to be one, possibly to dodge the draft. But you aren't even
intelligent enough to have passed the classes required for the degree.
You're a fraud, duke, and we know you're a fraud.
