Hi Erik, I assume you are talking about the Physics Fundamentals quiz. In the future please include which course you're asking about in your post. Ideally in the subject so other students who have the same question can easily find it.

While units are very important in Physics, when inputting the answers online you do not need to include the units. The answer input should be only numbers or decimals. Which units to use should be clear from the problem, but you can always ask if you have questions!
