GCSE COMBINED SCIENCE: TRILOGY Higher Tier Physics Paper 2

shows five different metal samples. Figure 1 A student placed a magnet close to each metal sample. Describe what happened. The paper clip in Figure 2 is not a permanent magnet. Explain what would happen if the paper clip was removed and brought close to the south pole of the permanent magnet. Write down the equation that links gravitational field strength (g), mass (m) and weight (W). [1 mark] The student added more paperclips to one end of the magnet. The maximum number of paperclips the magnet could hold was 20 Each paper clip had a mass of 1.0 g gravitational field strength = 9.8 N/kg Calculate the maximum force the magnet can exert. A student investigated how the height of a ramp affects the acceleration of a trolley down the ramp. Figure 3 shows some of the equipment used. Figure 3 Plan an investigation to determine how the height of the ramp affects the acceleration of the trolley. [
