1.What is meant by tangential speed?
It’s a linear speed in the circular path.
2.Distinguish between tangential speed and rotational speed.
Tangential is the speed of the circular path, but for the rotational speed is the speed of the number of revolutions in a certain time. Tangential speed is also depending on the distance of radius.
3.What is the relationship between tangential speed and distance from the center of the rotational axis? Give an example.
Tangential speed is directly proportional of the distance and rotation speed. If one of the speed increase, the other one will also increase.
1. I think their rotational speed is the same, because the number of the revolution is the same. His friend has the greater tangential speed because the distance of radius is bigger.
3. I think the rotational speed is the same because the distance of radius has no realtionship with the rotational speed.
