A student investigates the speed of a ball rolling down a ramp. The student records their data in the table below. Which of these best explains the student’s data? A. The speed of the ball increases as the ball rolls down the ramp because the force acting on the ball is greater than the force of gravity.
B. The speed of the ball increases as the ball rolls down the ramp because the forces acting on the ball are unbalanced.
C. The speed of the ball decreases as the ball rolls down the ramp because the forces acting on the ball are balanced.
