A ball is rolled across a floor under two different conditions. Each time the ball is rolled, it starts out at the same speed. The diagram below shows the initial position, final position, and initial frictional force applied to the ball each time. Explain how the results support Newton's first law, which states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. Responses AThe results support the idea that frictional force is what causes the ball to slow and come to a stop. Without the frictional force acting on the ball, the ball would be able to keep rolling.The results support the idea that frictional force is what causes the ball to slow and come to a stop. Without the frictional force acting on the ball, the ball would be able to keep rolling. BThe results support the idea that frictional force is what causes the ball to change direction. Without the frictional force acting on the ball, the ball would be able to keep rolling.The results support the idea that frictional force is what causes the ball to change direction. Without the frictional force acting on the ball, the ball would be able to keep rolling. CThe results support the idea that frictional force is what causes the ball to begin rolling. Without the frictional force acting on the ball, the ball would not be able to start rolling.The results support the idea that frictional force is what causes the ball to begin rolling. Without the frictional force acting on the ball, the ball would not be able to start rolling. DThe results support the idea that frictional force is what causes the ball to change direction. Without the frictional force acting on the ball, the ball would not be able to start rolling.
