Are remembering units for this equation, and others, necessary? Or are they given on the test?

Knowing the units of variables helps, because you'll know when to multiply or divide variables to get what you're looking for (essentially dimensional analysis). You will be provided units for variables specified in the question, but you won't be told what the units are for variables in specific equations.

What equation do you mean? is there a specific equation you are referring to? The test requires you to answer with correct units and sig figs. I do not believe that they give you the units.

Units 100% should be memorized. It makes solving the problems much quicker and will allow you to finish earlier without having to think about it. We will not be given these on the tests

While there are some units on the equation sheet given, it is probably best to know units as best you can.

I don't think units are given on the test, they are something you should know because it helps when you need to cancel out units to get your final answer

The test required students to know correct units as well as significant figures.
