Motion and Types of Motion

Short Questions

1. What is motion?
Answer : Change in position of an object.

2. What is linear motion?
Answer : Motion in a straight line.

3. Give one example of linear motion.
Answer : A moving train.

4. What is oscillatory motion?
Answer : Back-and-forth motion.

5. Give one example of oscillatory motion.
Answer : A swinging pendulum.

6. What is circular motion?
Answer : Motion in a circular path.

7. Give one example of circular motion.
Answer : A rotating fan.

8. What is periodic motion?
Answer : Motion that repeats at fixed time intervals.

9. Give one example of periodic motion.
Answer : The Earth revolving around the Sun.

10. What is random motion?
Answer : Motion with no fixed path or direction.

11. Give one example of random motion.
Answer : A butterfly flying.

12. What is speed?
Answer : Distance covered in a unit of time.

13. Write the formula for speed.
Answer : Speed = Distance ÷ Time

14. What type of motion do the hands of a clock show?
Answer : Circular motion.

15. What type of motion do marching soldiers show?

Long Questions

1. What is uniform linear motion? Give an example.
Answer : When an object moves at a constant speed in a straight line, it is called uniform linear motion.
Example: A car moving at the same speed on a straight road.

2. What is non-uniform linear motion? Give an example.
Answer : When an object changes its speed while moving in a straight line, it is called non-uniform linear motion.
Example: A bus stopping and starting in traffic.

3. What is the difference between oscillatory motion and circular motion?
Answer : Oscillatory Motion: Back-and-forth movement (e.g., a swing).
Circular Motion: Motion in a round path (e.g., a rotating fan).

4. How does speed affect motion?
Answer : Speed tells us how fast or slow an object moves. A higher speed means the object moves faster, and a lower speed means it moves slower.

5. Explain the motion of a bicycle when riding on a road.
Answer : The wheels of the bicycle show circular motion. The movement of the bicycle on the road is linear motion. The rider may also move in a non-uniform motion if speed changes.
