Question

True or false: If there is no air resistance, both balls land at the same time.

I say false.

Answer 1

Hmm you might be correct, but considering that some balls don't have the same compacity nor mass then I would assume one of them falls faster then the other. But thx! :)

Answer 2

I would say true. Without air resistance, both balls will fall at the same rate due to gravity. This is known as the principle of equivalence and was famously tested by Galileo in the 16th century.
