8.4 Working with Vectors Flashcards
What are Vector quantities?
A quantity which has both magnitude and direction
Give 4 examples of Vector quantities:
- Displacement
- Velocity
- Acceleration
- Force/weight
What are Scalar quantities?
A quantity which has magnitude only
Give 4 examples of Scalar Quantities
- Distance
- Speed
- Time

Description of Velocity
Rate of change of displacement
Unit for Velocity
metres per second (m s^-1)
Description of Acceleration
rate of change of velocity
Unit for Acceleration
metres per second per second (m s^-2)
Description for Force/weight
Described by magnitude, direction and point of application
Unit for Force/weight
newton (N)
Description of Distance
Measure of length
Unit for Distance
metre (m)
Description of speed
Measure of how quickly a body moves
Unit for speed
metres per second (m s^-1)
Description of Time
Measure of ongoing events taking place
Unit for Time
