Below are sample questions representative of the exercises included on this worksheet and related 9.48 Newton's Third Law and Force Pairs skill assessments:

Problem 1Difficulty: Mastery

A heavier skater and a lighter skater push directly apart from rest. A student claims the heavier skater must exert the larger force. What is the best rebuttal?

AThe heavier skater exerts a larger force, but the lighter skater pushes for more time.

BThe lighter skater exerts a larger force because the lighter skater accelerates more.

CEach skater exerts an equal force on the other; the lighter skater accelerates more because its mass is smaller.

DThe forces cancel on both skaters, so any acceleration must come from friction.

Solution & Explanation:The third-law pair has equal magnitude during the skater-skater interaction. The lighter skater's greater acceleration follows from the same size force acting on less mass.

Problem 2Difficulty: Mastery

A team designs a safer bumper for a cart collision. Which statement correctly applies Newton's third law to the design goal?

AThe bumper makes the moving cart's force larger so it bounces away faster.

BThe bumper cannot make one cart's force smaller than the other's; it can change contact time and reduce peak forces for both.

CThe bumper eliminates the reaction force on the other cart.

DThe bumper works by making the heavier cart exert less force than it receives.

Solution & Explanation:In a collision, the two carts exert equal and opposite forces at every instant. A bumper can spread the interaction over more time, often reducing peak force and damage.

Problem 3Difficulty: Mastery

Use the force probe display. Probe 1 measures cart A's force on cart B as +12 N. The same positive direction is used for both probes. What should probe 2 measure for cart B's force on cart A?

A+24 N.

B0 N.

C+12 N.

D-12 N.

Solution & Explanation:The paired force has equal magnitude and opposite direction. With the same sign convention, the second reading is negative when the first is positive.
