Galileo's Experiment on the basis of First Law Of Motion

 On the basis of first law of motion Galileo stated that object moves with constant speed when no force acts on them

Details of Experiment

• Galileo took the marble, a ramp and started the experiment by rolling it down the ramp.

• Using a water clock, Galileo measured the time it took for the rolling ball to reach a known distance down the inclined plane.

• After numerous trials, it was noted that the time taken for the ball to roll the entire length of the ramp was equal to double the amount of time it took for the same ball to only roll a quarter of the distance.

• In short, if one doubled the amount of distance the ball travelled, it would travel four times as far. Through this experiment, Galileo concluded that, if an object is released from rest and gains speed at a steady rate (as it would in free-fall or when rolling down an inclined plane), then the total distance, s, travelled by the object is proportional to the time squared needed for that travel.

• Mathematically s ∝ t2

  Galileo Stated that a falling object gains an equal amount of velocity in equal intervals of time. This also says that the speed increases at a constant rate as it falls.
