What keeps the force of a ball on a string moving in a circle?
The centripetal force, directed towards the center of the circle, keeps the ball on a string moving in a circle. This force is provided by the tension in the string, which constantly pulls the ball towards the center, preventing it from moving in a straight line. The ball's velocity remains tangential to the circle due to the centripetal force acting perpendicular to the velocity vector, resulting in circular motion.
If A ball is moving in a circular horizontal path the net force on the ball is in which direction?
The net force on the ball is directed towards the center of the circle, providing the centripetal force required to keep the ball moving in a circular path. This force is perpendicular to the velocity of the ball at any given moment.
What is the magnitude of the tension in the string when the ball is at the bottom of the circle?
The magnitude of the tension in the string at the bottom of the circle is equal to the sum of the gravitational force acting on the ball and the centripetal force required to keep the ball moving in a circular path.
What force causes a ball to accelerate around a pole?
The centripetal force is what causes a ball to accelerate around a pole. It is directed towards the center of the circular path and keeps the ball moving in a curved trajectory.
What keeps a ball moving downhill?
The force of gravity pulls the ball downhill, causing it to accelerate as it moves. As long as there is a slope for it to roll on, the ball will continue moving downhill until it reaches a flat surface or encounters a force that slows it down.

How does a roulette ball stop?
The roulette ball stays in motion due to centrefugal force. Since the ball is moving fast it "wants" to just go straight (Newton's 1st law) but the contact force of the metal track exerts an inward force that keeps it moving in a circle. Eventually, as the ball loses momentum, the force of gravity will be greater and the ball will then fall into a pocket.

What force is responsible for a tennis ball moving forward after it gets hit by a tennis racket?
The ball keeps moving forward because of its momentum, which is not a force.
The force keeping a ball on a string moving in a circle is called what?
centripetal
Newton's 1st law of motion states that a moving object will go in a straight line unless an outside force changes this motion What outside force prevents the planets from moving in a straight line in?
It's not that there is some force keeping the planets from falling into the sun; the sun's gravity prevents the planets from travelling in a straight line out of the solar system. If you throw a ball in a straight line then it keeps going, but if you throw a ball on a rope tied to a pole then the rope pulls the ball toward the pole and keeps the ball moving in a circle.

What is meant by the critical velocity of a ball moving in a vertical circle?
The critical velocity of a ball moving in a vertical circle is the minimum velocity required at the top of the circle to prevent the ball from losing contact with the track. Below the critical velocity, the ball will fall off the track at the top of the circle.
What would happen to an object if the centripetal force acting on it stops?
Picture a ball on a string being whirled about the head of an experimenter. If the string breaks, the centripetal force disappears. The ball leaves on a tangent path form its (previous) circular path. Yes, it's that simple. The string provided centripetal force, by virtue of its tensile strength, to the ball to keep that ball moving in a circle. When the string broke, there was no force left to accelerate the ball "in" and keep it moving in an arc.
