There are various methods to measure acceleration due to gravity. At Higher level all rely on one of the equations of motion. The measurements required will depend on the equation used.

The acceleration due to gravity is almost the same at all ... is usually assumed to be that given by the international gravity formula. In the British Isles, the mean variation is approximately ...

When Da Vinci set up his experiment, he focused specifically on the acceleration of the falling ... same rate as the objects are accelerating due to gravity, it’d create a isosceles right ...

Before the parachute opens: Immediately on leaving the aircraft, the skydiver accelerates downwards due to the force of gravity ... still accelerating but its acceleration decreases as time ...
