How Did the Magician Make the Ball Defy Gravity?

What forces are at play when the ball stops moving down the hill?

Is gravity the only force acting on the ball?

Explanation of the Magician's Trick:

When the ball stops moving down the hill, it appears to defy gravity, but in reality, multiple forces are at play.

Gravity, friction, and the normal force are the key forces affecting the ball's motion in this scenario.

As the ball rolls down the hill, gravity is pulling it downward, providing the force that causes the ball to accelerate. At the same time, the force of friction and the normal force acting on the ball are also present.

Newton's Second Law states that the greater the mass of an object, the more force it will take to accelerate the object. In this case, the mass of the Earth and the mass of the ball play a role in the forces affecting the ball's motion.

Once the ball reaches a certain point on the hill, the frictional force (along with air friction) equals the parallel component of gravity, causing the ball to stop accelerating and appear to defy gravity.

So, while it may seem like magic, the stopping of the ball's motion down the hill is actually a result of the balance of forces acting on it.
