Section 5.1 Action-Reaction Pairs (Newton’s Third Law)

Exercises Activities

1.

When a book is sitting at rest on a flat table, there are two forces acting on it. Identify these two forces and explain why they are not Newton’s 3rd Law pairs.

2.

Identify the Action-Reaction (Newton’s 3rd Law) pair for each force acting on the book from the previous question, which is sitting at rest on a flat table.
