Write down the equation that links kinetic energy (EkE_kEk), mass (mmm), and speed (vvv).
A surveillance drone is flying horizontally at a constant speed of 18 m/s. At this speed, the drone has a kinetic energy of 729 J. Calculate the mass of the drone.
Practise AQA GCSE Physics Energy changes in a system, and the ways energy is stored before and after such changes with exam-style questions for Foundation and Higher tier. 64 questions covering Energy stores and systems, Changes in energy, Energy changes in systems, and Power, 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.
