SUMMARY
A 1-inch diameter steel ball bearing requires a slope of approximately 3.57 degrees on a frictionless surface to initiate movement. This conclusion is derived from the analysis of gravitational forces acting on the ball bearing, where the component of gravitational force parallel to the slope must exceed the inertial resistance. The calculations demonstrate that the sine of the angle of inclination must equal the ratio of the ball's weight to the normal force acting on it.
