3 A box is being pulled across a rough floor at a constant speed. What can you say about the work
done by friction?

B friction does no work at all
C friction does positive work
D cannot be determined

4 Oiling the chain of a bicycle makes it run smoother. Why does this happen?

A The oil increases the friction between the gear cogs and the chain making them turn more easily.
B The oil decreases the friction between the gear cogs and the chain by acting as a lubricant
making them turn more easily.

C The oil decreases the friction by making the gear cogs contract and the chain links expand
D The oil increases the friction by keeping the gear cogs and the chain cool.

16 Science Award 1 mark if they answer both (a) Force due to friction (b)
Force due to friction is the force that opposes the relative
motion between two surfaces in contact.
Award 0.5 marks if only (a) or (b) is right
17 Science Award 1 mark totally: Half mark for each: Filled High in first
blank and Low in second blank
Any other answer / No answer 0
18 Science Award 1 mark totally: 0.5 marks each for any two forces such
as: - magnetic force - electrostatic force - gravity
0.5 mark for any one example written correctly
Any other answer 0
19 Science Award 1 mark if they write: The presence of chloroplasts in
plant cells enables plants to manufacture their own food
through photosynthesis. Animal cells cannot perform
photosynthesis as they do not have chloroplasts, so they
depend directly or indirectly on plant for food.
