A student investigated how changing the mass of a trolley affects its acceleration.
For one setup, the student recorded three values for the acceleration of the trolley: 2.42 m/s2,2.47 m/s2,2.43 m/s22.42\text{ m/s}^2, \quad 2.47\text{ m/s}^2, \quad 2.43\text{ m/s}^22.42 m/s2,2.47 m/s2,2.43 m/s2
Calculate the mean acceleration of the trolley.
When the total mass of the trolley was 1.8 kg1.8\text{ kg}1.8 kg, the acceleration of the trolley was 1.35 m/s21.35\text{ m/s}^21.35 m/s2.
Calculate the resultant force acting on the trolley. Use the equation: resultant force=mass×acceleration\text{resultant force} = \text{mass} \times \text{acceleration}resultant force=mass×acceleration
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.
