  • Use the same interaction-force magnitude with each object’s mass to calculate acceleration

AP Physics 1: Algebra-Based 2.3 A Describe the Interaction of Two Objects Using Newtons Third Law and a Representation of Paired Forces Exerted Questions question 1

[Maximum number: 1]

Consider the situation in which your hand is pushing a book across a rough desktop with lots of friction. Of the many forces involved, consider only these two individual forces: the force on your hand from the book and the force the book is experiencing from your hand. While the book is accelerating from rest to its final velocity, which statement best compares the force experienced by your hand compared with that experienced by the book?

A

Force on book > force on hand

B

Force on hand > force on book

C

Force on hand = force on book

D

The relationship between these two forces depends on the frictional force.
