A student carries out an experiment to investigate the relationship between force and acceleration for a trolley on a track.
Write down the equation that links acceleration (aaa), mass (mmm), and resultant force (FFF).
In one test, the resultant force on the trolley is 0.485 N0.485\text{ N}0.485 N and the total mass of the trolley is 0.80 kg0.80\text{ kg}0.80 kg. Calculate the acceleration of the trolley. Give your answer to 2 significant figures.
Describe how the student could improve their investigation to reduce the effect of random errors.
Practise AQA GCSE Physics Forces and motion with exam-style questions for Foundation and Higher tier. 83 questions covering Describing motion along a line, Forces, accelerations and Newton's Laws of motion, and Forces and braking, matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
