WebNov 16, 2024 · The magnitude of its position vector is constant (it is the radius of the circle) so the time derivative of the magnitude is zero, but the speed of the object is not zero. In other words, in general d r → d t ≠ d r → d t where r → ( t) is a position vector. Share Cite Improve this answer Follow answered Nov 16, 2024 at 2:49 gandalf61 WebWe can see this represented in velocity as it is defined as a change in position with regards to the origin, over time. When the slope of a position over time graph is negative (the derivative is negative), we see that it is moving to the left (we usually define the right to be positive) in relation to the origin. Hope this helps ;)
