scalar and vector quantities

• What is the difference between scalar and vector quantities?

  - scalar quantities have a magnitude (size) only

  - vector quantities have both magnitude and direction
• Give 6 examples of scalar quantities?

  - mass

  - temperature

  - speed

  - energy

  - distance

  - time
• Give 6 examples of vector quantities?

  - displacement

  - weight

  - force

  - velocity

  - acceleration

  - momentum
• How can we represent vector quantities?

  - with an arrow (length of the arrow tells us the magnitude and the direction in which the arrow is pointing tells us the direction)
