1. 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).
2. Explain, in your own words, how friction affects the acceleration of a toy car rolling down a ramp.
3. If you have two ramps, one covered in sandpaper and one covered in smooth plastic, and you roll the same toy car down both, which car will reach the bottom first? Explain why.
