Question

One of the difficulties in studying mechanics is that many common words are used with highly specific technical meanings, among them velocity, acceleration, position, speed, and displacement. The series of questions in this problem is designed to get you to try to think of these quantities like a physicist.

Answer the questions in this problem using words from the following list:

position

direction

displacement

coordinates

velocity

acceleration

distance

magnitude

vector

scalar

components

Consider a physical situation in which a particle moves from point A to point B. This process is described from two coordinate systems that are identical except that they have different origins.

The __________ of the particle at point A differ(s) as expressed in one coordinate system compared to the other, but the __________ from A to B is/are the same as expressed in both coordinate systems.

Explanation / Answer

1: Position

2: Displacement
