Motion check in quiz

Distance

• The total length travelled

• How far an object is from its starting point in a straight line

• Location of an object relative to a defined zero point

Displacement is distance combined with

• direction
• speed
• velocity
• magnitude

What is Vector definition?

• A quantity that has magnitude and direction

• A vector that has longitude and direction

• A quantity that has magnitude and scalar

• A vector that has direction and angle

A person walks 50 metres directly north, stops, and then travels 32 metres directly south. What is their displacement?

• 82 metres north

• 18 metres north

• 28 metres north

What is acceleration?

• an increase in speed

• a decrease in speed

• a change in direction

• all of these are examples

Label each as a "scalar" or a "vector"

• time

• scalar (kg)

• density

• scalar (kg/m^3)

• force

• vector (N)

• velocity

• scalar (s)

• mass

• vector (m/s)
