The statements that best describe the movement of the bowling ball moving down a flat bowling lane at a constant speed are:
C. Its movement shows Newton's first law of motion.
F. Its movement remains the same unless a force acts upon it.
Explanation:
- Newton's first law of motion (the law of inertia) states that an object will remain at rest or move at a constant velocity unless acted upon by an unbalanced force. Since the bowling ball is moving at a constant speed, it demonstrates this principle.
- Statement F corresponds directly to this idea, indicating that the bowling ball's movement will not change unless a force acts on it.
The other options (A, B, D, and E) do not accurately describe the situation as presented. For example, statement A implies there are unbalanced forces acting on the ball, which is not the case if it is moving at a constant speed without any change in direction or acceleration.
