Answer 2

$\huge\rm { _!! Answers !_! }$

1. Fill in the blanks-

1. The SI unit of speed is ${\underline {\rm {\red { m/s \: or \: m {s}^{-1}. }}}}$

2. The resting position of a bob of pendulum is called ${\underline {\rm {\red { mean }}}}$ position.

3. When a body doesn't change its position with respect to its surrounding it is said to be at ${\underline {\rm {\red { rest. }}}}$

4. Speed of a motor vehicle is measured by an instrument called ${\underline {\rm {\red { speedometer }}}} .$

5. Distance travelled by a vehicle is measured by an instrument called ${\underline {\rm {\red { odometer }}}} .$

6. Time taken by a pendulum to complete one oscillation is called ${\underline {\rm {\red { time \: period }}}}.$

7. The metallic ball used in the pendulum is called ${\underline {\rm {\red { bob}}} } .$

8. A diagram showing relationship between two variable a quantities each measured along one pair of axes is called ${\underline {\rm {\red { graph }}}} .$

9. An instrument showing the time by the shadow of a pointer cast by the sun on to a graduated plate is called ${\underline {\rm {\red { sundial }}}} .$

10. Basic unit of time is ${\underline {\rm {\red { second }}}} .$

$\huge\rm { _!! Additionally !_! }$

• The change in the position of a body with respect to time and reference to the object is called motion.

• If the body doesn't show change in the position of a body with respect to time and reference to the object, then it is at rest position.

• The SI unit of time is second.

• Speed is the distance covered by an object in unit time.

$\rm { Speed = \dfrac{ Distance}{ Time } }$

From this above-mentioned formula you can find distance and time.

$\rm { Distance = speed \times time}$

$\rm { Time = \dfrac{Distance}{Speed}}$
