Question

question 3: what happens to the skater when you add more and less friction? answer:

Explanation:

Friction opposes motion. More friction (e.g., rough surface) slows the skater quickly, reducing glide distance and speed. Less friction (e.g., smooth ice) allows the skater to move faster, glide longer, and lose energy slower (due to less resistance).

Answer:

• When more friction is added: The skater slows down more rapidly, has a shorter glide distance, and loses kinetic energy faster due to greater opposing force from friction.
• When less friction is added: The skater can move faster, glide for a longer distance, and loses energy (and speed) more slowly as there is less resistance opposing the motion.
