Galileo Experiment
Galileo’s Experiment
In the 16th Century AD, Galileo Galilei performed a very interesting experiment. He considered a ball moving on a horizontal very smooth surface with some speed. He observed that the ball slows down after some time as an unbalanced frictional force exerted by the table opposes the motion of the ball.
Conclusion: He concluded that an object body moves with uniform velocity when no external force is applied.
Another experiment of Galileo leading to the same conclusion involves a double inclined plane. He observed the motion of balls rolling on an inclined plane. When a ball rolls down an inclined plane, its speed increases, whereas while rolling up an inclined plane, the speed decreases.
Which of the following are correct ? (a) Galileo observed that when a ball rolls down an inclined plane, its speed increases. (b) Galileo observed that when a ball rolls up an inclined plane, the speed decreases. (c) Galileo observed that a ball moves with uniform velocity when no external force is applied. | |||
