Question

Which of the following is/are true about the attributes of a uniform circular motion?
a. The velocity points in a tangential direction at every point of motion.
b. The speed changes throughout the motion of the body.
c. The acceleration being perpendicular to the velocity points towards the center.

  1. Only a and b are correct
  2. Only b and c are correct
  3. Only c and a are correct
  4. All are correct

hintHint:

Uniform circular motion is the motion of a particle moving at a constant speed on a circle.

The correct answer is: Only c and a are correct


    The true attributes of uniform circular motion are:
    The velocity points in a tangential direction at every point of motion.
     The acceleration is perpendicular to the velocity points towards the center.

    Sam wants to modify the formula for acceleration
    I.e., a = (v – u)/ t
    Where v = final velocity, u = initial velocity, t= time, a = acceleration, to suit the special case of freefall of a ball dropped from the top of a building. He chooses to make the following substitutions in the formula.
    a. v= 0
    b. u= 0
    c. a= 9.8 m/s2
    Identify the correct substitutions.
