Question

Taking the traffic pole as a reference point, Sam observed the state of the passenger inside the yellow bus. He found that the passenger was in motion w.r.t. the traffic pole. What is the frame of reference in which this observation is made?

  1. Earth
  2. Yellow bus
  3. Moon
  4. Car

hintHint:

Earth is the frame of reference.

The correct answer is: Earth


    • Motion means the distance covered by an object in a particular time with respect to its surroundings (called reference point).
    • If person A and person B are standing in a bus. Person A is at rest with respect to person B. But person A is in motion with respect to a person standing outside the bus or a tree.

    Which of the following motions repeat themselves after equal intervals of time?
    1. The motion of the Moon around the Earth
    2. The motion of the hour hand of a clock
    3. The motion of a tennis ball during a match
    4. The motion of a seesaw when children are playing

    the motion of the moon around the earth and the motion of the hour hand of the clock is a periodic motion hence, they repeat themselves after equal intervals of time.

    Samuel decides to find the average speed of his parent’s car while they take a drive to a park 21 km away from their home. Which of the following would yield him the most accurate result?
    a. Look for milestones throughout the journey and note down the distance traveled against the respective time stamps. Later use the formula, average speed = total distance traveled / total time taken to calculate the average speed.
    b. Keep an eye on the odometer and note down the distance traveled by car against the respective time stamps. Later use the formula, average speed = total distance traveled / total time taken to calculate the average speed.
    c. Keep an eye on the speedometer and note down the speed at different locations. Later use the formula average speed = sum of all the speeds/ no. of observations to calculate the average
