Why are some forces considered to be noncontact forces?

• Objects don't have to touch each other to experience a force

• Objects must be far apart in order to exert a force

• Objects push each other apart to increase their distance

• Objects must be big to exert a force strong enough to notice

Why is friction force considered a contact force?

• It only affects solid objects

• It is produced when objects slide past one another

• It always acts in the same direction

• It acts in a direction opposite to the object's motion

What is the net force acting on this box?

• 100 N to the right

• 25 N downward

• 50 N to the right
