Q: When an object rotates at a uniform circular motion. Which of the following change at each point?
  • A. pressure
  • B. velocity
  • C. inertia
  • D. mass
Correct Answer: Option B - Uniform circular motion involves an object travelling a circular path at constant speed and each point as the direction of velocity changes. The direction of the tangent drawn at a point of the circle is the direction of velocity of the object at that point.
B. Uniform circular motion involves an object travelling a circular path at constant speed and each point as the direction of velocity changes. The direction of the tangent drawn at a point of the circle is the direction of velocity of the object at that point.

Explanations:
