Awesome! Thank you.RUber said:That is correct.
You could also have seen that 40/3 rps can be directly translated into a speed by replacing the r in rps with the distance covered in 1 revolution (2 pi r).
That would give you the same result ##\frac{80 \pi r}{ 3}##m/sec.
Ohh... I see. Thank yougneill said:Yes, that works. You need to carry the "seconds" unit through to the end though. The period T has seconds as its unit.
Otherwise you'll end up with a "velocity" with units of distance rather than distance/time.
The formula for calculating the velocity of a rotating disc is v = ωr, where v is the velocity, ω is the angular velocity, and r is the radius of the disc.
The radius of a rotating disc directly affects its velocity. As the radius increases, the velocity also increases. This is because the linear velocity of a point on the disc's edge is directly proportional to the radius.
No, the velocity of a rotating disc is not constant. The linear velocity of each point on the disc's edge is constantly changing as it rotates. However, the angular velocity, which is the rate of change of the disc's angle, remains constant.
The mass of a rotating disc does not directly affect its velocity. However, a disc with a larger mass may require more energy to rotate at a certain velocity compared to a disc with a smaller mass.
Yes, the velocity of a rotating disc can be negative. This occurs when the disc is rotating in the opposite direction of the chosen reference point. In this case, the velocity is considered negative because it is moving in the opposite direction of the positive chosen reference point.
