Question

select the answer from the menu.
if a ball rolls at a constant rate on a flat surface, the motion is due to forces.
options: gravitational, frictional, electromagnetic, balanced

Explanation:

To determine the force causing a ball to roll at a constant rate on a flat surface, we use Newton's first law of motion. An object in motion with constant velocity (or rate) has a net force of zero, meaning the forces acting on it are balanced. Gravitational force acts vertically, frictional force opposes motion, and electromagnetic force is not relevant here. So the motion is due to balanced forces.

Answer:

balanced
