The linear speed of a point on the rim is also called the:
ATraditional speed
BTerrestrial speed
CTangential speed
DTerritorial speed
Answer & Solution
Correct answer: C. Tangential speed
1. A point on a spinning rim moves along the circle.
2. At any instant its velocity points along the tangent.
3. That linear speed of a point on the rim is called the tangential speed.
4. So the answer is tangential speed.
