A ball on the end of a string is whirled with constant speed in counterclockwise horizontal circle. At point A in the circle, the string breaks. Before the string breaks, is there a net force acting on the ball?
An object moves in a circular path around a center point. At a location A, four possible paths are shown for the object. Path 1 points radially outward. Path 2 points horizontally outward. Path 3 points tangent to the circle, in the direction of motion. Path 4 curves in a wider path than the radius of the circle.
Multiple Choice
yes, pointing inwards towards the center of the circle
yes, pointing outwards away from the center of the circle
