FORCES AND SHAPE

2 marks · Normal

An ice skater glides across an ice rink and gradually slows down until stopping. Use scientific reasoning to explain why the skater eventually stops, and what type of force is involved.

Work this out on paper, then compare with the answer and worked solution below. With a free account you can submit written answers for marking.

Show answer

Must show: friction/force opposes motion, skater slows down because of this force

Common mistakes: Omitting mention of friction

Marking points

B1 · 1 mark · States that friction slows the skater

B2 · 1 mark · Explains friction opposes movement and removes energy

Worked solution

Friction between the skates and the ice acts against the skater's motion, gradually slowing them down until they stop.
