Question

Quizplus · Accepted Answer

The acceleration of a cart rolling down an inclined plane is approximately constant, as long as there is no air resistance, friction, or other external forces acting on it. This is because the force of gravity causes a constant acceleration downwards, which is independent of the mass of the cart. However, if there is friction or other external forces, the acceleration may not be constant but may decrease over time.
