eddyy08 said:A ball is swung around in a vertical circle at constant speed. Where is the ball when the tension in the rope is at maximum / minimum?
I know where the ball is, how would I explain it?
eddyy08 said:Thank you -
at maximum tension its at the bottom of the circle
eddyy08 said:Force of gravity, centripetal acceleration toward the center of the circle, and probably something else
Centripetal force is a force that acts on an object moving in a circular path, always directed towards the center of the circle. It is responsible for keeping the object moving in a curved path instead of a straight line.
Centripetal force is necessary for an object to maintain a circular motion. In the absence of centripetal force, the object would continue moving in a straight line tangent to the circle.
The formula for calculating centripetal force is F = mv²/r, where F is the centripetal force, m is the mass of the object, v is the velocity of the object, and r is the radius of the circular path.
In a vertical circle at constant speed, the centripetal force remains constant throughout the motion. This is because the speed of the object remains the same and the radius of the circle also remains constant.
No, in addition to centripetal force, the object is also subject to gravitational force. However, in a perfectly circular motion, the centripetal force and gravitational force balance each other out, resulting in a constant speed for the object.
