1. 1(a)(i)1 markDefine the term 'acceleration' and state its units.
2. 1(a)(ii)3 marksState Newton's second law of motion in words AND the associated equation.
3. 1(b)(i)5 marksOn the grid provided in Figure 1 (page 7), plot a graph of speed against time.
4. 1(b)(ii)1 markSuggest a reason why the velocity remains unchanged for the first 0.5 seconds after the light turns red.
5. 1(b)(iii)1 markWhat feature of the graph shows that the car's deceleration was uniform?
6. 1(b)(iv)4 marksUse your graph to determine the distance that the car travelled after the lights turned red to when the car stopped.
7. 2(a)(i)1 markamplitude
8. 2(a)(ii)1 markphase difference between Points P and Q on the string
9. 2(a)(iii)2 marksspeed.
10. 2(b)(i)1 markState the phase difference in the motion of the points on the string labelled X and Y.
11. 2(b)(ii)2 marksDistinguish between the terms 'antinode' and 'node' when used to describe stationary waves on a string.
12. 2(b)(iii)1 markState the number of antinodes shown on Figure 3.
13. 2(c)(i)5 marksOn the grid provided in Figure 4 (page 11), plot a suitable graph to respresent the data.
14. 2(c)(ii)2 marksHence, determine the frequency of the standing wave.
15. 3(a)(i)2 marksState Hooke's law.
16. 3(a)(ii)6 marksDescribe how this arrangement could be used to determine the spring constant and hence, the mass of the rock sample.
17. 3(b)(i)5 marksUse the graph to find the work done in extending the spring up to Point B.
18. 3(b)(ii)2 marksBeyond Point A, the spring undergoes inelastic deformation. Explain the term 'inelastic deformation'.
19. 4(a)5 marksBy referring to Figure 7, explain the origin of upthrust and how upthrust determines whether an object will float or sink.
20. 4(b)(i)1 markDetermine the weight of water that would be collected in the beaker.
21. 4(b)(ii)3 marksFor (b) (i), calculate the volume of water displaced and hence, determine the density of the stone.
