Praxis 5005 Practice Question
Which of the following best explains why an ice skater is able to coast on ice for a long distance without pushing off in a straight line across the ice?
Correct Answer: B
Rationale: An ice skater can glide smoothly due to the low friction between the skate blades and the ice, which allows them to maintain momentum over a longer distance. Option B correctly states that the force of friction on the blades is less than that on the ice, enabling prolonged coasting.
Option A is incorrect; the friction on the blades is minimal, not greater. Option C misrepresents the situation, as the ice does not exert a forward force; rather, it offers minimal resistance. Option D is also wrong because buoyant force, relevant in fluids, does not significantly apply to skaters on ice.
