Explain how galileo used a thought experiment of a ball on a ramp to conclude that an object would stay in constant motion if no net force acted on it.

1) He placed a ball in center of ramp(deepest part), and thought that "it would not attain speed until I push it"..

2)He placed a ball on the top of the ramp, and thought "it would be continue in motion until I stop it"

Then he stated first law of Inertiawhich you know very well

Hey there!

Galileo rolled the ball up the ramp and stopped. As the ramp was lowered, the ball rolled farther. If the ramp were perfectly smooth and level, the ball should continue forever if nothing disturbed it.

Hope this helped you
