Class 10 Science | Equation of motion for free fall

Method

With the help of your parents or teachers, drop a stone from different heights, such as the roof of a house or a school building.
Place a tin or some other sound-producing object on the surface of the ground, so that you know when the stone hits the ground.
Find the time the stone takes to hit the ground.
Find the height of the house, school building and so on, using the equation of motion.
Take the average of your measurements to reduce the probable error.
Finally, measure the actual height with a measuring tape and mention the error in the calculated height.
