what do scalar quantities only have?

scalar quantities have magnitude (size) only.

2
New cards

what do scalar quantities not have?

3
New cards

examples of scalar quantities

  • mass

  • temperature

  • speed

  • energy

  • distance

  • time

4

6
New cards

what is displacement?

distance in a specific direction

7
New cards

how can we represent vectors?

using an arrow

8
New cards

what does the length of the arrow represent?

the length of the arrow represents the magnitude (size) of the vector.

9
New cards

what does the direction of the arrow represent?

the direction of the arrow represents the direction of the vector.
