Question

..
① Define the following terms : Reference frame, position.
Distance and displacement.​

Answer 1

Answer:

Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.The origin of the symbols for displacement (∆s) and distance (∆s) is spatium, the Latin word for space (like the space between two locations).If you run a 5K on a circular course, your distance traveled is 5 kilometers, regardless of where you started and finished. Distance is a scalar quantity. Displacement is an object's change in position, only measuring from its starting position to the final position.It is important to note that the distance traveled does not have to equal the magnitude of the displacement (i.e., distance between the two points). Specifically, if an object changes direction in its journey, the total distance traveled will be greater than the magnitude of the displacement between those two points.
