Quick answer: The suvat equations connect displacement, initial velocity, final velocity, acceleration and time for motion in a straight line with constant acceleration. This Physics 11-12 test on suvat equations has 8 questions worth 20 marks, to do in 40 minutes: choosing equations, cyclist and canyon drop. The mark scheme is on a separate page; free printable PDF.
This test covers the equations of motion, free fall and velocity-time graphs. Use a calculator, show your working and give units with every final answer. Take g = 9.81 m/s² and ignore air resistance. The test is worth 20 marks.
