Best ResponseYou've already chosen the best response.0displacement is equivalent to distance one lap is the perimeter of the circle= circumference = 2 * pi* r 1/2 lap = 1/2 * 2 * pi* r and r is the radius 150

Best ResponseYou've already chosen the best response.0Ok, I see how that is, but that is describing the distance. My book says displacement is the straightline distance between two points. Would that mean I double the radius because it would be equal to the diameter?

Best ResponseYou've already chosen the best response.0displacement is how far you are from the place you started. not how far you have traveled to get there.

Best ResponseYou've already chosen the best response.0So would I just double the radius because the car went half the circle?

Best ResponseYou've already chosen the best response.0So, to be clear, the displacement would be 300m?

Best ResponseYou've already chosen the best response.0thats the way it looks to me yes, the car is 2 radiuses from where it started

Best ResponseYou've already chosen the best response.0magnitude is the measure of the displacement

Best ResponseYou've already chosen the best response.0consider displacement as a vector, it has both length and direction ...

Best ResponseYou've already chosen the best response.0stand corrected does this mean we are not dealing with vectors?

Best ResponseYou've already chosen the best response.0we are dealing with a vector, but just the magnitude of it

Best ResponseYou've already chosen the best response.0That makes sense to me now. I have some more questions. Could you help me with them? I am taking an advanced physics class and my teacher never explained any of this, she just assigned the homework, so I am not always sure if I am on the right track.
