01.1 iron and steel will be attracted
(to the magnet)
aluminium, copper and tin will
not be attracted (to the magnet)

01.2 the paperclip would still be
attracted to the magnet
because of induced magnetism allow the paper clip becomes an
induced magnet
allow because the paper clip is a
temporary magnet
allow there is a magnetic field at
the south pole

02.1 Level 3: The method would lead to the production of a valid
outcome. All key steps are identified and logically sequenced.
5–6 AO3
Level 2: The method would not necessarily lead to a valid
outcome. Most steps are identified, but the plan is not fully logically
sequenced.
3–4 AO1
Level 1: The method would not lead to a valid outcome. Some
relevant steps are identified, but links are not made clear.

measurements
• place one wooden block under the ramp
• vary the height by placing a different number of wooden blocks
• measure the height of the ramp using a metre rule
• measure the distance travelled using a metre rule
• measure time taken using light gates (and computer/datalogger)
• measure time taken using a stopclock or ticker timer
• release trolley from the same position each time
• release the trolley without applying a force
results
• repeat at the same height and calculate a mean
• repeat for different heights
• calculate acceleration using a = (v-u)/t or a = v2- u2
