Question

can you go round the curve with the following acceleration? explain

a-zero acceleration?
b-constant acceleration?

Answer 1

@chosenmatt

Answer 2

acceleration is simply a change in velocity correct?

Answer 3

velocity is just the direction that you are moving in + how fast you are moving aka the speed

Answer 4

if you have 0 acceleration you just have a constant velocity hence a constant speed and direction. Does all this make sense?

Answer 5

i have to agree with @1DEA

Answer 6

I DON'T KNOW IF IT'S CORRECT BUT THIS QUESTION RELATED TO UCM LESSON (UNIFORM CIRCULAR MOTION )

Answer 7

yes that makes sense that it's part of that lesson.

Answer 8

but do you understand what I said previously?

Answer 9

Dont worry hun.

Answer 10

yeah thanks guys ♡

Answer 11

I'm a bit puzzled at your response...but I am going to continue hoping that you actually got what I said. So if we are turning, we might not actually be decreasing speed right? But we are most certainly changing direction. This "change in direction" conflicts with the idea of zero acceleration as if we have zero acceleration, as previously mentioned, we would have no change in direction. As such it's impossible to have 0 acceleration while turning. Does this all make sense?

Answer 12

what u said above is only for { zero acceleration } yeah ?

Answer 13

yes. After all zero acceleration means constant velocity.

Answer 14

okey what about (constant acceleration ) ? >> I hope u do not kill me but i'm not into physics alot

Answer 15

I certainly don't hope to kill you (would be quite a stain on my current non-existent criminal record) :). But I hope that you are understanding what I am saying and not just copying my response to just complete your homework. But anyways using the same logic we can think about constant acceleration. If acceleration as I previously defined is the change in velocity, a constant acceleration would be a constant change in velocity. So is it possible for us to change our velocity (which I'll remind you is speed + direction) in a constant way and make a turn? Quite so, if we change our direction in a constant way, we would most certainly make a turn.

Answer 16

Since the problem is still open, I will add this:
If you are rounging a curve is your direction changing?......if it is then your velocity is changing.......if your velocity is changing then your acceleration is changing.... If you can answer those questions, then you will have an answer.

Answer 17

I may be wrong, but I would SWAG a "b."
