Question

In his Galileo inclined plane experiment he proved that: a. The distance is proportional to the square of time

b. The distance is proportional to time
c. The distance is proportional to a third of the time
d. Distance and time are the same

Answer 1

Option a

Step-by-step explanation:

Galileo's experiment of inclined plane provides the measurement of acceleration with accuracy with the help of simple equipment.

The ultimate objective of the experiment was to prove that when other external forces are absent like the one due to air resistance, all the objects fall at a constant accelerated rate towards the Earth.

Thus he measured the influence of gravity on the free falling object accurately and observed that the distance covered by these objects when released from rest and moving at a steady rate, then the distance traveled by the object is proportional to the square of the time taken.

From his findings:

`D = (gH)/(2L)t^(2)`

where

D = distance

L = Inclined plane length

H = Height of the inclined plane
