An engineer is testing the aerodynamics of a scale model sports car in a wind tunnel.
State the equation that relates the resultant force (FFF) acting on an object, its mass (mmm), and its acceleration (aaa).
During one trial, the scale model has a mass of 0.64 kg and experiences a horizontal resultant force of 0.435 N.
Calculate the acceleration of the model car. Give your answer to 2 significant figures.
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.
