Textbook Question
Chapter 2.1, Problem 1cT
All forces arise from interactions between objects, but the interaction can take different forms.
Which of the forces exerted on the block require direct contact between the block and the object exerting the force?
Which of the forces exerted on the block do not arise from direct contact between the block and the object exerting the force?
We will call forces that depend on contact between two objects contact forces. We will call forces that do not arise from contact between two objects non-
