Below are sample questions representative of the exercises included on this worksheet and related 12.36 Weight, Normal Force, and Apparent Weight skill assessments:

Problem 1Difficulty: Mastery

Which strategy is most reliable for solving weight, normal-force, and apparent-weight problems?

AAlways set the normal force equal to mg before reading the problem details.

BUse the object's speed instead of acceleration to decide the scale reading.

CIgnore all applied forces because only gravity affects apparent weight.

DDraw the relevant forces, choose an axis, apply Newton's second law, and solve for the normal force rather than assuming N = mg.

Solution & Explanation:Normal force depends on the complete force balance along the relevant axis. Newton's second law shows when N equals mg and when it must be larger, smaller, or zero.

Problem 2Difficulty: Mastery

A 10 kg package is pressed horizontally against a vertical wall scale, and the wall scale reads 50 N. What is the best interpretation?

AThe package's weight has become 50 N downward.

BThe package's mass has become 50 kg.

CThe wall scale measures a 50 N horizontal normal force, while the package's weight is still 98 N downward.

DThe wall scale reads the friction force, so the normal force is zero.

Solution & Explanation:A vertical wall scale measures the contact force perpendicular to the wall, which is horizontal. The gravitational force is still mg = 98 N downward.

Problem 3Difficulty: Mastery

At the bottom of a roller-coaster valley, a rider's scale-like seat force is 2.5mg. What does this mean physically?

AThe rider's mass has become 2.5 times larger.

BThe rider's apparent weight is 2.5 times normal because the seat must provide upward centripetal acceleration as well as support weight.

CGravity has become 2.5 times stronger at the bottom of the valley.

DThe rider is weightless because the path is curved.

Solution & Explanation:At the bottom, N - mg = mv²/r. A large upward normal force is needed to curve the rider's motion upward, so apparent weight exceeds true weight.
