The toy truck will experience the greatest amount of friction on the carpet.
- Friction is a force that opposes relative motion between bodies.
- It arises due to the interlocking between the irregularities of the two surfaces in contact.
- The smoother the surface, the lesser are the irregularities and thus lesser is the frictional force.
- Out of the given surfaces, tile is the smoothest while the roughest is carpet.
- Toy truck rolls fastest on tile and slowest on the carpet.
