Question
Pick the odd one out.
- A flying bug
- A running child
- A giant wheel
- A fish moving in water
Hint:
A giant wheel is different from other options.
The correct answer is: A giant wheel
- When an object is moving with no specific speed or direction is called random motion.
- The giant wheel moves in a circular motion while, the others perform random motion.

Which of the following motions repeat themselves after equal intervals of time?
- The motion of the Moon around the Earth
- The motion of the hour hand of a clock
- The motion of a tennis ball during a match
- 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
