A bit of help about a Sinusoidal graph.

So I'm supposed to describe how an object would be moving depending on a sinusoidal graph. Personally, I would describe it as something that would be slowing down and then stopped for a moment, then it sped up and stopped, then slowed down, etc.
But thats not one of my answer choices so I don't know whether to pick 'none' or 'someone moving back and worth'. Can you help?

a pendulum is one example

anonymous · Answer

These are the answer choices and picture by the way   

       The object is moving in a negative direction.
        The object is moving back and forth.
        The object is moving in a positive direction.
        We can't tell anything from the velocity alone.
        None of these

danjs · Answer

That is a velocity vs time graph or position vs time graph?

danjs · Answer

either way they will look similar

danjs · Answer

The object is moving back and forth

anonymous · Answer

Velocity vs. Time I think

danjs · Answer

Think of a pendulum...the velocity is at the maximum when the bob is at the lowest point and decreases towards the top of the swing

danjs · Answer

so the velocity will be periodic, harmonic motion, like a spring bouncing up and down

Okayyy, thanks a lot! Just wanted to make sure since I don't  really have anyone to ask for  help.

danjs · Answer

You had the right idea, slowing down, stopped, speeding up, slowing down, stopped... exe..
