Question
Observe the picture below. The position of which of the objects can be considered as a reference point to study the state of a passenger in the yellow bus?
a. The child
b. The car
c. The traffic pole
d. Another passenger in the same bus
e . A person travelling in the car
f. One of the yellow strips on the road
- a, b and e only
- e and f only
- c, d and f only
- f and c only
Hint:
C, d and f only is the correct option.
The correct answer is: c, d and f only
- A reference point is a point with which we can find the position of an object either object is moving or at rest.
- We can tell the motion of an object by comparing its position with respect to its reference point.
- We can check motion of yellow bus passengers by using pole, another vehicle passenger and yellow stripes as reference point.

Sheena wanted to measure the displacement between two points of her house. She has fixed an iron nail at each point. Which of the following methods can she follow?
a. Tie a thread to the first nail and then tie it to the other nail. Measure the length of the thread between those two points using a ruler.
b. Tie a thread to the first nail and tie the other end of the thread to the second nail so that the thread is taut and measure the length of the thread used using a ruler.
c. Fix one end of the measuring tape to the first nail and stretch it towards the second nail and record the measurement.
If the line between two points is straight, then only it will show displacement.
