Are any of you guys good with physic? Mind helping a fellow hfb members out with a few physic terminoology lol?

Re: Physic
okay.....what is it that you need help ????...explain please.....not sure about "physic"?????...is this anything like "psycho"?????
just kidding...
what is it that you need help with...

Re: Physic
Ok for constant acceleration and constant velocity arent they the same thing? Both have a change in displacement over a certain time interval?180 gallon RR wild discus, harlequins, congos, rainbow, pleco, cardinals, rummynose, rcs, and amanos. Â 2260 eheim pressurize co2 4x54 tek lights

Read : http://www.physicsclassroom.com/Class/1DKin/U1L1e.html
Excerpt : An object with a constant acceleration should not be confused with an object with a constant velocity. Don't be fooled! If an object is changing its velocity – whether by a constant amount or a varying amount – it is an accelerating object. An object with a constant velocity is not accelerating.

Re: Physic
T = time
D = distance
D/T = velocity = speed (60 mph cruse control )
D/T*T = acceleration = petal to the metal (change in speed)'Dear Lord,' the minister began, with arms extended toward heaven and a rapturous look on his upturned face. 'Without you, we are but dust ...'
He would have continued but at that moment my very obedient daughter who was listening leaned over to me and asked quite audibly in her shrill little four-year old girl voice, 'Mom, what is butt dust?'Comment

Re: Physic
What PhishPhreek said, but over a very-very-very tiny period of time :).
It means that since velocity is "change of position over tiny period of time" objects with non-zero velocity can't stay in the same place by definition of what velocity is.
And since acceleration is "change of velocity over tiny period of time" => objects with non-zero acceleration can't have non-changing velocity (as a vector) by definition of what acceleration is.Comment

Re: Physic
Yeah zulaab I was at that site and read the same lines lol. I got confuse thats why I ask. Thx ak 71 for clirification.180 gallon RR wild discus, harlequins, congos, rainbow, pleco, cardinals, rummynose, rcs, and amanos. Â 2260 eheim pressurize co2 4x54 tek lights

Re: Physic
Another way to "differentiate" velocity and accaleration is :
Velocity is the first time derivative of distance, (M/hr)
Acceleration is the second time derivative of distance, (M/hr/hr),
rate of acceleration is the third time derivative of distance, (M/hr/hr/hr).
In the old days before NEA dumbed down education you had to take calculus before/with physics.
I guess that today it is more important to know how you feel about acceleration than understand it.Comment
