Question

The SI unit of acceleration is ___.

  1. m/s
  2. m/s2
  3. km/h
  4. km/h2

hintHint:

Acceleration is the rate of change of velocity. 

The correct answer is: m/s2


    Acceleration = Change in velocity / time taken 
    SI unit of acceleration = SI unit of velocity / SI unit of time
    SI unit of acceleration = m over s cross times 1 over s = m over s squared 

    ANSWER: SI unit of acceleration = ms-2

    Selena is classifying different moving objects into two categories, i.e., rotational motion and periodic motion. She has the following motions to classify:
    a. The motion of a swing
    b. The motion of the Earth around the Sun
    c. The motion of a giant wheel
    d. The motion of the blades of a fan at a particular speed
    e. The motion of the hands of a clock
    f. The motion of a roller coaster
    g. The motion of a merry-go-round
    h. The motion of a pendulum
    She could identify some of the above objects, which can be put in both categories. What are those?

    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
