D.
gravity

5. What is a force?


A.
a pull only


B.
only gravity


C.
a push or a pull


D.
balanced actions

Answer 1

All of them are C. Just did the test and got 100%

Answer 2

1. She would want a balanced force so she doesn't fall but, well, keep her balance.
2. Frictional force because when an object slows down it's because a higher amount of friction is acting on it.
3. It would be magnitude and direction because is like the size of the object and they need to know how much force it will take to move it.
4. Is the same as 3...
5. A push and a pull are a force.

I hope this helps!
