b. Object slides w/out friction.

c. Object slows due to kinetic friction. SOLVED
d. Static friction prevents sliding. SOLVED

e. Object is motionless (diagram below).
f. Object falling w/ no air resistance
g. Object falling at constant/terminal velocity
h. The ball is rising in a parabolic trajectory.

Diagram for e.|dw:1383882433194:dw|

doc.brown · Answer

I would keep e simple, an object with no velocity in any direction.  No forces acting in one direction more than another.|dw:1383882817633:dw|

doc.brown · Answer

a and b are the same?

kittiwitti1 · Answer

No, the diagrams are available, we have to label the vectors @doc.brown

kittiwitti1 · Answer

Also the diagrams for A and B are different

kittiwitti1 · Answer

@doc.brown I think A has an Fa?

doc.brown · Answer

Are a and b both without friction?
