Uniform velocity (1 Viewer)

[mcbec]

hey, im doin revision q's on apps of calculus to physical world, which i totally suck at coz i hate physics crap. anyway theres a question that asks about uniform velocity - what is uniform velocity???

 

[acmilan]

Velocity thats not changing.

 

[mcbec]

what does that mean?? (in words and/or algebraically)

 

[speed2]

i think its when acc. = 0

 

[acmilan]

algebraically: dv/dt = 0, where v = velocity

In words, the velocity doesnt change. If i travel at 40 m/s, i always travel at 40 m/s, it never changes.

Isn't it where your velocity is a constant with no variables ? (eg v=30, can't change)

\edit\ damnit, ac beat me haha

Velocity is constant which means that the speed does not change (since velocity means speed but it can be positive and negative).

Because it is not speeding up or slowing down acceleration is 0. Displacement can be anything really.

x = ?
v = constant
a = 0

As you can see anyway, the Intergration of a=0 for t is a constant.

yeah i got it already, but thanks anyway. for some reason i understand things algebraically much easier than if they are said in words... lol its weird. anyway, thanks.
