If the force supporting a load is perpendicular to the surface of contact between the load and its support, this force is defined to be a ---

• opposing force

• friction force

• normal force

• tension force

The word normal means ----

• below a surface

• perpendicular to a surface

• parallel to a surface

• attached to a surface

When is the normal force less than the object's weight?

• when the object is on an incline

• when the object is sliding

• when the object is frictionless

• when the object moving upward

The symbol for the normal force is often confused with ----

• the symbol for neon

• the symbol for nitrogen

• the symbol for newton

• the symbol for north

Which two forces are parallel to the slope?

• motion and friction

• weight and normal

• weight and gravity

• normal and friction
