Imagine you have a toy car rolling down a ramp. Describe what happens to the car's speed if you make the ramp surface rougher (increase friction).
Explain, in your own words, how friction affects the acceleration of a toy car rolling down a ramp.

Quick comprehension check
“A toy car is rolling down a ramp. If you replace the ramp with a material that creates less friction, what will happen to the car's speed compared to the original ramp? Imagine a toy car rolling down a ramp covered in carpet. Now imagine the same car rolling down the same ramp covered in ice. How will the difference in friction affect the car's speed in each case? ”
