Only one (horizontal) force acts on the mass.Priyadarshini said:
I don't understand.Doc Al said:
Please identify the forces acting on the mass.Priyadarshini said:
There is no centripetal force as the mass is not accelerating.Doc Al said:
That would be true if viewed from the rotating frame, which requires the inertial centrifugal force. If so, what is the acceleration?Priyadarshini said:

Circular motion is the movement of an object along a circular path or trajectory. It occurs when an object moves around a fixed point, known as the center of the circle, with a constant speed.
The main difference between linear and circular motion is that in linear motion, an object moves along a straight line, while in circular motion, an object moves along a circular path. In linear motion, the velocity and acceleration are in the same direction, while in circular motion, the velocity is constantly changing, and the acceleration is directed towards the center of the circle.
The resultant force in circular motion is the net force acting on an object moving along a circular path. It is directed towards the center of the circle and is responsible for the change in direction of the object's velocity. The magnitude of the resultant force is equal to the mass of the object multiplied by the centripetal acceleration.
Centripetal force is the force that acts towards the center of the circle, keeping an object moving along a circular path. It is a result of the object's inertia, which causes it to resist changes in its motion. In circular motion, the centripetal force is equal to the resultant force.
Some examples of circular motion and resultant force in our daily lives include the Earth orbiting around the Sun, a car turning a corner, a satellite orbiting the Earth, and a rollercoaster moving along its track. In all of these cases, an object is moving along a circular path, and the resultant force is responsible for keeping the object in that path.
