Question

A student is investigating how the type of surface affects how far a toy car rolls after being released down a ramp.

The student tests four different surfaces at the bottom of the ramp:

Surface A: Smooth tile

Surface B: Sandpaper

Surface C: Carpet

Surface D: Wood floor

They release the same toy car from the same height each time and measure the distance the car travels after it leaves the ramp.

Here are the results:



Surface Distance Traveled (cm)
A 120
B 35
C 50
D 100



Based on the data, which surface has the least amount of friction, and what evidence supports this conclusion?

(1 point)
Responses

Surface A, because the car traveled the shortest distance.
Surface A, because the car traveled the shortest distance.

Surface B, because the car traveled the farthest.
Surface B, because the car traveled the farthest.

Surface A, because the car traveled the farthest.
Surface A, because the car traveled the farthest.

Surface C, because it is soft and slows the car down.

Answer 1

Surface A, because the car traveled the farthest (120 cm), indicating it experienced the least friction.
