Question

chen is testing the friction of three surfaces. he pushes the same ball across three different surfaces with the same force and measures the distance the ball rolls over each surface. the ball moved ten inches across surface 1, six inches across surface 2, and fifteen inches across surface 3. which could most likely describe the three surfaces? surface 1 is ice, surface 2 is gravel, and surface 3 is blacktop. surface 1 is gravel, surface 2 is ice, and surface 3 is blacktop. surface 1 is blacktop, surface 2 is gravel, and surface 3 is ice. surface 1 is blacktop, surface 2 is ice, and surface 3 is gravel.

Explanation:

Step1: Understand friction concept

Friction opposes motion. Less friction means ball rolls farther.

Step2: Analyze surface - friction relationship

Ice has low friction, gravel has high friction, black - top is in - between.

Step3: Match distances to surfaces

The ball rolled the farthest (15 inches) on surface 3, so surface 3 has least friction (ice). The ball rolled the least (6 inches) on surface 2, so surface 2 has most friction (gravel). Then surface 1 is blacktop.

Answer:

C. Surface 1 is blacktop, Surface 2 is gravel, and Surface 3 is ice.
