Which must be true for motion to begin to happen? What factor is important in determining if motion occurs?
What will be an ideal response?
Answer: The gravity force parallel to the surface must be greater than the resisting strength. If the resisting strength of the material is small, then objects move only on a low slope,. If the resisting strength is large, then objects only move on a steep slope. Slope angle is also very important in determining motion, as driving forces increase with increasing slope angle, and resisting strength increases with decreasing slope angle.
