Will a ball placed tightly (radius of ball=width of groove) in a groove(length of grove along radius) on a rotating disk have any motion along the groove. The frictional force is zero.
Yes, outwards.NANDHU001 said:Will a ball placed tightly (radius of ball=width of groove) in a groove(length of grove along radius) on a rotating disk have any motion along the groove. The frictional force is zero.
To clarify: By "move outwards" I meant increase the distance to the center of rotation, move radially relative to the table.NANDHU001 said:But still I can't imagine how the ball should move outwards.
It's a different question, not a different manner. Without rotation it will not move outwards.NANDHU001 said:I'll put the question in a different manner ... rotation is stopped.
The purpose of studying this motion is to understand the principles of rotational motion and to analyze the effects of different factors on the motion of the ball, such as rotational speed and friction.
The rotational speed of the disk directly affects the linear velocity of the ball and can also impact the centripetal force acting on the ball, which can change its trajectory and speed.
Friction between the ball and the groove can cause the ball to slow down or change direction, depending on the direction and magnitude of the force of friction. It can also impact the energy and momentum of the ball.
The shape and angle of the groove can impact the trajectory and speed of the ball, as well as the amount of friction acting on the ball. A steeper angle or a curved groove may result in a faster or more curved motion for the ball.
Understanding this type of motion can be applied to many real-world scenarios, such as analyzing the movement of a ball bearing in a machine or the motion of a roller coaster on a curved track. It can also be useful in designing and optimizing rotational machinery and vehicles.
