A student carries out an experiment to estimate the acceleration due to gravity, ggg.
She drops a solid plastic sphere from a balcony and measures the time, ttt, it takes to fall to the ground through a height, hhh.
She records the following measurements:
Calculate the value of g g\,g from these measurements.
Use the equation:
g=2ht2 g = \frac{2h}{t^2} g=t22h53 exam-style questions on Edexcel GCSE Physics 2.2 Speed, velocity and acceleration. Each one has a worked solution and a mark scheme showing where the marks go.
