Below are sample questions representative of the exercises included on this worksheet and related 9.47 Newton's Second Law and Net Force skill assessments:

Problem 1Difficulty: Mastery

A 12 kg object has a net force of 0 N while it is already moving. What does Newton's Second Law predict?

AIt accelerates in the direction it is moving

BIts acceleration is 0 m/s², so its velocity does not change because of net force

CIt must immediately stop because no force acts

DIt accelerates at 12 m/s² because it has mass

Solution & Explanation:Fnet = ma means 0 N = 12 kg x a, so a = 0 m/s². With zero acceleration, the object's velocity remains constant unless a net force appears.

Problem 2Difficulty: Mastery

Use the accompanying equation wheel. Which rearranged form should be used to find mass from net force and acceleration?

Am = Fnet + a

Bm = a/Fnet

Cm = Fnet x a

Dm = Fnet/a

Solution & Explanation:Starting from Fnet = ma, divide both sides by a to solve for mass: m = Fnet/a.

Problem 3Difficulty: Mastery

Two students push a 20 kg cart in opposite directions. Student A pushes 90 N east. The cart accelerates 1.5 m/s² east. How hard does Student B push west?

A120 N

B90 N

C30 N

D60 N

Solution & Explanation:The needed net force is 20 kg x 1.5 m/s² = 30 N east. If 90 N east minus Student B's westward push equals 30 N east, Student B pushes 60 N west.
