Poll: Physics Question

[snowdog]

Force= mass * acceleration

s is the position vector.

I was lied to by school then was always taught s= distance in metres.

It is, but in a certain direction, hence vector.

 

[InvaderGIR]

You've completely lost me.

What?

 

[mejinks]

v = u + at
v(squared) = u(squared) + 2as
s = ut + (half)at(squared)
s =(half) (u + v)t

And thats is the equation of motion.

 

[Edward01]

v = u + at
v(squared) = u(squared) + 2as
s = ut + (half)at(squared)
s =(half) (u + v)t

And thats is the equation of motion. Thus the plane will not take off.

Wow that takes me back years to AS mechanics!!

[Inquisitor]

F=Ma

L = T - V

 

[mejinks]

I remember doing that!

 

[misterPK]

Reminds me of when our mechanics teacher brought an empty beer can into the lesson to help teach us friction by sliding it down a desk.

PK!

V = I * R
I = V/R
R = V/I

VIR = Character from B5

You would think that if you got as far as being able to take that test, you would already know that there is 100cm in a metre, and that obviously 1cm = 100th of a metre.

It's there for conversion purposes, and yes, you would be expected to know it anyway

Remember this:

fo = fv/(v ± vs)

where

fo is the observed frequency
v is the velocity of the waveform
vs is the velocity of the source
f is the emitted frequency
± is plus or minus; plus (+) is used when motion is away from you and minus (−) is used when motion is toward you


The standard equation for the observed frequency of a waveform for a moving source.

Love the poll

Love the poll

Eastern Europeans are great aren't they

If a tree Falls in a woods and no one is there to hear it...

 

[Wyrdo]

If a tree Falls in a woods and no one is there to hear it...

If a tree falls on FrostedNipple and no one is there to witness it...

What a shame

...do the trees cry?

Mr Doppler?

No they just whisper causing wind or so my parents would have me believe as a child
