Here are the expected questions for the chapter Motion And Measurement of Distances for NCERT class 6 Science paper.

NCERT Class 6 Science Chapter 10 | Expected Questions

1. What is rectilinear motion?

When objects move along a straight line, it is called rectilinear motion. Examples: the movement of a bus and car.

2. What is circular motion?

When objects move along a circular path, it is called circular motion.

3. What is periodic motion?

When objects repeat their motion after sometime, it is called periodic motion.

4. When a ball moves on the ground, what motion does it undergo?

It undergoes rectilinear motion and rotational motion.

5. What motion does the needle in a sewing machine undergo?

Periodic motion

6. Examples of two objects undergoing circular motion.

Blades of a fan, hands of a clock

7. March past of soldiers is an example of …………………………..

Rectilinear motion

8. What is motion?

Motion is the change in the position of an object with time.

9. Which unit of measurement is now used?

International System of Unit (SI Unit)

10. Unit of length in SI …………………….

Metre

11. Explain one characteristic of circular motion

In circular motion, an object moves in such a way that its distance from a fixed point remains the same.

12. Write the similarities and differences between the motion of a bicycle and a ceiling fan

Similarity: Both the bicycle and the fan show circular motion.
Difference: The bicycle also undergoes rectilinear motion but the fan does not undergo rectilinear motion.

13. Name three examples of periodic motion

The pendulum of a clock, the string of a guitar, a child in a swing

14. Name 3 examples of objects showing circular motion

The blades of a fan, the wheels of a car and the minute hand of a clock
