Question 1.
What is the position vector for the point (3, 4)?
Show hintHide hint
Use the coordinate values directly.
Question 2.
If a particle has a position vector r = 2i + 3j, what are the coordinates of the particle?
Show hintHide hint
Extract the coefficients of i and j.
3Question 3.
What is the formula for calculating displacement?
- ∆r = r' + r
- ∆r = r' - r
- ∆r = r × r'
Show hintHide hint
Look for the subtraction of vectors.
4Question 4.
True or False: The position vector can only represent locations in three dimensions.
- True
- False
Show hintHide hint
Think about how many dimensions we discussed.
Question 5.
Two particles are moving: Particle A at (1, 1) moves to (4, 4). Particle B at (2, 2) moves to (5, 5). Calculate the displacement vectors for both and determine which particle underwent a greater displacement.
Show hintHide hint
Calculate each step carefully, keeping track of each component.
Question 6.
A car moves from point (3, 2) to (6, 8) and then to (10, 14). Calculate the total displacement from its original position to its final position.
Show hintHide hint
Split the total journey into segments and calculate displacements for each segment.
