Below are sample questions representative of the exercises included on this worksheet and related 4.2 Balanced and Unbalanced Forces skill assessments:

Problem 1Difficulty: Mastery
Two identical toy cars get the same push. One travels farther on tile than on a rug. Which final explanation best fits the investigation?
AThe rug creates more friction, so it slows the car sooner than the tile.
BThe tile has more friction because the car travels farther.
CThe rug removes the car's gravity, so it stops.
DThe same push means surface friction cannot matter.
Solution & Explanation:The only changed variable is the surface. Since the car travels less on the rug, the rug likely has greater friction.
Problem 2Difficulty: Mastery
A ball moves in a circle on the end of a string at a steady speed. Why are the forces still unbalanced?
AThe ball's direction is constantly changing.
BThe ball's speed number is steady.
CGravity is not a force on moving balls.
DThe string has no effect on motion.
Solution & Explanation:Motion includes direction. Even at a steady speed, changing direction means the ball's motion is changing.
Problem 3Difficulty: Mastery
Use the playground slide model. A child starts at rest near the top, slides down, and reaches a flat rough mat at the bottom. Which prediction best fits the forces?
AGravity speeds the child down the slide, and friction on the rough mat slows the child at the bottom.
BFriction speeds the child down the slide, and gravity stops on the mat.
CBalanced forces make the child speed up down the slide.
DThe child keeps speeding up on the rough mat because rough surfaces add motion.
Solution & Explanation:Gravity pulls the child down the slide. The rough mat has friction that acts opposite motion and slows the child.
