According to Newton's First Law, an object at rest will tend to do which of the following?

stay at rest

stay in motion

speed up

change in direction

What are the two ways we can have UNBALANCED forces?

1) unequal forces in opposite directions and 2) forces in same direction

1) forces in same direction and 2) equal forces in opposite direction

1) unequal forces in opposite directions and 2) forces in opposite directions but same sizes

you can't have unbalanced forces, forces will always balance each other out
