Educational worksheet about friction, illustrating concepts with a bicycle and hockey player, and asking questions to reinforce understanding.

- Friction slows down or stops moving objects.
- It is easier to walk on the sidewalk because it has more friction than ice, which is very smooth and offers little resistance to stop slipping.
- Friction is important because it allows us to walk without sliding, helps vehicles stop with brakes, and lets us hold and grip objects securely.
- Examples of friction in everyday life: using brakes on a bike or car, walking without slipping, and writing with a pencil on paper.
- To make a slide ride go faster, you could make the surface smoother (e.g., by adding wax or water) to reduce friction.
- To make a slide ride go slower, you could make the surface rougher (e.g., by adding sandpaper or carpet) to increase friction.
