Aim how can we distinguish between a vector and scalar quantity

Aim: How can we distinguish between a vector and scalar quantity?

Do Now:

What is the distance from A to B?

Describe how a helicopter would know how to travel from A to B

Distance = 10 km (scalar)

Displacement = 10 km East (vector)

1 unit = 2 km

Scalar

Scalar

  • Quantities having only magnitude (a number)

    • Ex:

      • Distance – 10 m

      • Mass – 5 kg

      • Time – 30 s

      • Speed – 50 m/s

      • Energy – 500 J


Vector

Vector

  • Quantities having both magnitude and direction

    • Ex:

      • Displacement – 10 m East

      • Velocity – 50 m/s West

      • Acceleration – 9.8 m/s2 down

      • Weight or Force – 50 N down


Representing a vector

Representing a Vector

  • A vector is represented by an arrow pointing in a direction and drawn to a selected scale

    • Ex: 4 m/s South

    • Determine an appropriate scale

      1 cm =

1 m/s
