Uniform Circular Motion

  1. What type of motion occurs when an object moves in a circular path with constant speed?
    • Uniform circular motion
    • An object moving with constant speed along a circular path is said to be in uniform circular motion​.
  2. Which force keeps an object in uniform circular motion?
    • Centripetal force
    • Centripetal force acts toward the center of the circle to keep an object moving in a circular path​.
  3. What happens to the direction of velocity in uniform circular motion?
    • Changes continuously
    • In uniform circular motion, the direction of velocity changes at every instant while speed remains constant​.
  4. Which celestial body exhibits uniform circular motion around the Earth?
    • Moon
    • The moon moves around the Earth in a nearly uniform circular motion due to gravitational force​.
  5. What is the shape of the path traced by an object in uniform circular motion?
    • Circle
    • In uniform circular motion, an object follows a circular path with constant speed​.
  6. Which quantity remains constant in uniform circular motion?
    • Speed
    • Although direction changes, the speed of the object remains constant in uniform circular motion​.
  7. Which type of acceleration acts on an object in uniform circular motion?
    • Centripetal acceleration
    • Since velocity direction changes continuously, centripetal acceleration acts towards the center of the circular path​.
  8. What happens to an object in circular motion if centripetal force is removed?
    • Moves tangentially
    • If centripetal force is removed, the object moves tangentially to the circular path in a straight line​.
  9. Which example illustrates uniform circular motion in daily life?
    • Cyclist on a circular track
    • A cyclist moving with constant speed along a circular track exhibits uniform circular motion​.
  10. Which motion of artificial satellites around Earth is an example of uniform circular motion?
    • Orbital motion
    • Artificial satellites move around the Earth in uniform circular motion due to gravitational attraction​.
