A student rode their bike from Park A to their house. They then rode their bike to Park C to meet a friend. Calculate the displacement.

• 5m East

• 7m

• 5m North East

• 7m North

A dog started walking North from point A. The dog walked 10m North before stopping and sniffing a pole. The dog then started travelling 3m East to a chip scrap on the ground. The dog spotted another dog 5m North and ran all the way over to say hello to it. Distracted by kids playing a ball game the dog then turned and ran 3m West towards the ball game. Exhausted from all the running, the dog collapsed (point B). What is the total distance travelled by the dog?

• 21m

• 18m

• 16m

• 15m

A dog started walking North from point A. The dog walked 10m North before stopping and sniffing a pole. The dog then started travelling 3m East to a chip scrap on the ground. The dog spotted another dog 5m North and ran all the way over to say hello to it. Distracted by kids playing a ball game the dog then turned and ran 3m West towards the ball game. Exhausted from all the running, the dog collapsed (point B). State the displacement in meters.

• 15 m North

• 15m

• 15 m West

• 15 m North West

Distance is defined as:

• A measure of how far an object has moved between start and finish.

• A measure of how fast an object is moving.

• A measure of the amount of matter in an object.

• A measure of the force exerted on an object.

Displacement is defined as:

• The total distance traveled by an object

• The change in position of an object between start and finish.

• The speed of an object in a given direction

• The rate of change of velocity

Describe the person's journey in the displacement graph below from 5-10 seconds.

• The person remains stationary for 5 seconds

• The person walked backwards 8m over 5 seconds

• The person accelerates for 5 seconds.

• The person decelerates for 5 seconds

What average velocity was the person travelling at between the 0 and 5 seconds?

• 0.8 m/s

• 4 m/s

• 0.8 m/s forwards

• 5 m/s upwards

An aeroplane travelled East over a 1000m tarmac/runway in 15 seconds. What is the average velocity that the plane travelled at?

• 66.67 m/s

• 75 m/s

• 80 m/s

• 85 m/s
