Kolbe Physics 10

14. A plane flies the 3 500 km to Melbourne from Perth in the morning and returns in the afternoon. The plane's displacement would be:

7. A boat with an outboard motor sets off from the west bank of a river to reach the east bank. Though the navigator aimed at the point directly across the river he landed some distance downstream. to reach the point he was aiming for, he should have:

13. A boat travelling upstream is travelling at 2.5 m s-1 but the current moving downstream is rated at 0.5 m s-1. The resultant velocity would be:

15. If there is a direct relationship between displacement and time in a graph from an experiment, then it can be said from the graph that:

1. Which of the following dimensions is a vector quantity?

5. A graph that shows a curve representing velocity must have on the axes:

10. Convert 90 km h-1 into m s-1.

8. A physics student noticed that her car travelled 300 m in 5.0 minutes when caught in a traffic 'jam' on the Kwinana Freeway. Her average velocity in this time would be:

4. When measuring a desk with a metre rule the amount of error is given as + or - 5.0mm. The smallest unit shown on the rule would be

3. How many significant figures are in the number 500 124.

12. A cyclist pushing the peddles of her bike creates a velocity of 10.0 m s-1. If there is a wind at her back of 0.5 m s-1, her resultant velocity would be:

6. The variable being measured in an experiment (shown on the vertical axis of a graph) is known as the:

9.Convert 2.5 m into the correct number of centimetres.

11. When an object undergoes a change in velocity it is said to be experiencing:

2. A vector quantity has:
