Question

what horizontal force acts on an ice skater speeding across the ice? (1 point) friction weight push pull

Explanation:

When an ice skater is moving across the ice, weight acts vertically (due to gravity). Push and pull are forces that would require another object or person to be actively applying them (like pushing off initially, but when "speeding across" without an external pusher/puller). Friction is a force that opposes the motion of the skater (even on ice, there is some friction, though it's low). Since the question is about a horizontal force acting during the motion (and not an initial push), friction fits as it acts horizontally against the skater's movement.

Answer:

friction
