Question

conduct an experiment to find 2s/ t² value for a freely falling body and also find the value of 'g' .​

Answer 1

Explanation:

(1) Take a long plastic tube of length nearly 200cm and cut it in half along the length of the tube.

(2) Use these tube parts as tracks.

(3) Mark the readings in cm along the track.

(4) Place the one end of the tube on the book or books and the other end on the floor as shown in the figure.

(5) Keep a steel plate on the floor at the bottom of the track.

(6) Consider the reading at the bottom of the track to be zero.

(7) Take a marble having enough size to travel in the track freely.

(8) Now release marble freely from a certain distance say 40 cm.

(9) Start the digital clock when the marble is released.

(10) It moves down on the track and strikes the steel plate. Stop the digital clock when a sound is produced.
