Exam points

  • identify equal-magnitude, opposite-direction interaction forces on two different objects
  • distinguish a Newton’s-third-law pair from balanced forces acting on one object
  • use equal interaction-force magnitudes with unequal masses to calculate or compare accelerations

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.
