Is it a net force? If it were, wouldn't the ball be accelerating inward? Doesn't that force just offset the ball pulling on the string?twotaileddemon said:The direction of the force is inward, perpendicular to the velocity at any given moment of time.
yeskeemosabi said:Is it a net force?
yes, it is , in the inward centripetal x direction.If it were, wouldn't the ball be accelerating inward?
No, that's Newton's 3rd law, the string pulls on the ball, and the ball pulls on the string, with a force equal in magnitude and opposite in direction, always.Doesn't that force just offset the ball pulling on the string?
Centripetal net force is the force that is required to keep an object moving in a circular path. It is always directed towards the center of the circle and is responsible for changing the direction of an object's velocity.
Some examples of centripetal net force include the force of gravity keeping planets in orbit around the sun, the tension force in a string holding a ball in circular motion, and the force of friction on a car making a turn.
Centripetal net force can be calculated using the equation Fc = mv^2/r, where Fc is the centripetal force, m is the mass of the object, v is the velocity, and r is the radius of the circular path.
If there is no centripetal net force acting on an object, it will continue to move in a straight line at a constant speed, rather than following a circular path. This is known as Newton's first law of motion.
Centripetal net force and centripetal acceleration are directly proportional. This means that as the force increases, so does the acceleration, and vice versa. The equation for centripetal acceleration is ac = v^2/r.
