Question

When drawing a free body diagram, which direction would you draw the arrow representing the normal force for an object on a level floor

Answer 1

Upwards

Step-by-step explanation:

when drawing free body diagrams you always point he arrow in the direction that it would move that object.

So gravity would move the object down, therfore the arrow is pointed down.

Normal force pushes the object up to oppose gravity therefore the arrow is also pointed up.

Furthermore...

If you push an object to the right, your force is moving the object to the right therefore the arrow would be pointed to the right also.
