Question

how do newtons laws of motion explain why it is important to keep the ice smooth on a hockey rink so that players can pass a puck as quickly as possible? smooth ice reduces the inertia of the hockey puck. smooth ice increases the force used to accelerate the hockey puck. smooth ice reduces the unbalanced forces that would slow the hockey puck. smooth ice decreases the reaction force that the ice exerts on the hockey puck.

Explanation:

Newton's first law states that an object in motion stays in motion unless acted on by an unbalanced force. Friction is an unbalanced force that slows moving objects. Smooth ice reduces sliding friction, which is the unbalanced force that would slow the puck. Inertia depends on mass, so smooth ice does not change it; it also does not increase acceleration force or reduce the normal reaction force.

Answer:

Smooth ice reduces the unbalanced forces that would slow the hockey puck.
