Question

Can the normal force on an object be directed horizontally?

Answer 1

For this case, the first thing you should do is take into account the definition of normal force.

By definition, we have:

• The normal force is that which is exerted on an object that is perpendicular to the surface.

If we define the coordinate system as:

1. Horizontal axis points to the right
2. Vertical axis points up

Then An object resting on a wall can have normal force in a horizontal direction.

Answer:

The normal force is perpendicular to the surface. The direction can be horizontal. Example: an object on a wall.
