A student wants to adapt their experiment to investigate how the mass of a trolley affects its average speed down a ramp.
Devise an experiment that would allow the student to investigate the effect of different masses on the average speed of the trolley.
53 exam-style questions on Edexcel GCSE Physics 2.2 Speed, velocity and acceleration, covering 2.2.1 Speed and distance–time graphs, 2.2.2 Acceleration and the uniform-acceleration equation, 2.2.3 Velocity–time graphs, and 2.2.4 Measuring speed, typical speeds and free-fall acceleration. Each one has a worked solution and a mark scheme showing where the marks go.
