Hi jbravo07 and welcome to PF. We do not give answers to questions, especially "fill in the blanks" type of questions. Tell us what you think the correct answer is and why you think so. Then we will give you guidance if your reasoning goes astray.

okay, i think the answers are

1. less than (F=ma)
2. less than (F=ma)
3. greater than (F=ma)
4. equal to (mass is the same anywhere)
5. less than (you weigh less on the moon than on earth)

im still getting it wrong, im not sure what concepts it is asking us about, please help!
Going backwards, your answer to question 5 is correct although your reason is not complete.
Your answer to question 4 is Ok and your reason is good.

Now for the rest. You need to say more than just F = ma. Let's look at question 1 (we will deal with questions 2 and 3 later). How does F = ma explain that the Force required to accelerate horizontally a 500-kg mass on the Moon is less than what is required to do the same thing on the Earth? In what direction is gravity on the Earth and on the Moon, vertical, horizontal or both?
