SherBear said:Does a turntable turn clockwise? Normal force up, mg down, Ff opposite of the motion if clockwise then it's counterclock wise?
LawrenceC said:The turntable is turning at constant speed so you are not concerned with tangential force here. We want to determine what the maximum speed is.
At the point of impending coin movement outward, what forces are exactly balanced?
The velocity of a coin on a turntable is directly proportional to its maximum velocity. This means that as the velocity of the coin increases, its maximum velocity also increases.
The radius of the turntable has a significant influence on the motion of the coin. As the radius increases, the coin will have a larger circular path and a higher maximum velocity. Conversely, a smaller radius will result in a smaller circular path and a lower maximum velocity.
The mass of the coin does not have a direct effect on its motion on the turntable. However, a heavier coin may require more force to maintain a constant velocity, resulting in a decrease in maximum velocity.
Yes, the speed of the turntable has a direct impact on the motion of the coin. A faster turntable will result in a higher maximum velocity of the coin, while a slower turntable will result in a lower maximum velocity.
The angle of the turntable has a significant influence on the trajectory of the coin. A steeper angle will result in a more elliptical path, while a shallower angle will result in a more circular path. This will also affect the maximum velocity of the coin, with a steeper angle resulting in a higher maximum velocity.
