The discussion revolves around a problem involving a 20 kg ball in constant circular motion, with a focus on centripetal acceleration and the forces acting on the ball, including gravitational force and tension in the string. The setup includes an angle of 10 degrees and a radius of 0.5 m.
Participants are actively exploring the relationships between the forces involved and questioning the assumptions about the forces acting on the ball. Guidance has been offered regarding the nature of centripetal force and the importance of drawing a free body diagram to clarify the forces at play.
There is an emphasis on understanding the balance of forces in circular motion, particularly with the angle of the string affecting the dynamics. Some participants express confusion about how forces at angles can balance out, indicating a need for further exploration of vector components.

As far as I got was F(net)=F(centripetal), then I was lost
brittylaurel said:What is an fbd?
brittylaurel said:Oh! The teacher told the class that there are only two forces acting on the ball. There is F(centripetal) and there is F(gravity) which is 196 N I got that from the information. What is an fbd?
It appears the string is at an angle...while another force is perpendicular to the object... If the object doesn't move up or down, doesn't that mean that something is balancing out the force? If so, how does a Force at an angle balance it out? (think vectors)brittylaurel said:Homework Statement
a 20 kg ball attached to a string is moving in constant circular motion. if theta= 10 degrees and the radius of its circular path is 0.5 m, what is the ball's velocity?
