# Gravity by Time of Flight

The value of acceleration due to gravity can be obtained by measuring the time of flight of a freely falling body, for a given distance.

# Objective

Measure accelration due to gravity by time of flight

# Procedure

- Attach the iron ball on the electromagnet
- Keep the contact sensor below, at a distance of several tens of centimeters
- Press START

# Discussion

The program assumes that there is no delay between the removal of the voltage applied to the coil and the detachment of the ball. This is not true and causes an error in the results.
