What would the hypothesis be for Does the mass of an object affect the falling time you have not tested it?

Answer 1

Before you test it, you could state the hypothesis in two different ways

You could say:

"The mass of a falling object has no effect on the time it takes to fall some distance."

Or you could say:

"The time a falling object takes to fall some distance depends on its mass."

You could use the same tests to investigate EITHER hypothesis.

The mass of a falling object has no effect on the time it takes to fall some distance assuming zero air resistance.
