I noticed how the textbook uses "s^-1" instead of "/s" (like Js^-1 instead of J/s). Also, ms^-1 is the same as m/s. However, I was wondering if there was any special reason that it's notated with specifically a negative exponent. Is the reason chemistry-related or is it just a preference or neither?

I don't think there should be any special reason for this difference. Either way, the difference doesn't concern us because it wouldn't affect our marks.

I don't think it really matters. For me personally, it is easier to use m/s as opposed to ms^-1, especially dealing with a problem that has many units. It is easier for me to visualize which units cancel each other out.

There is no difference between notations, so you can use either notation when writing out your problems!
