Short Answer Questions
Q7. Define 'motion'. State whether motion is absolute or relative, and give one reason for your answer.
Q8. Distinguish between translatory motion and rotational motion. Give one real-life example of each from your school or home.
Q9. What is oscillatory motion? How is it different from circular motion? Give one example each.
Q10. Can an object exhibit more than one type of motion simultaneously? Explain with the example of a wheel rolling on the ground.
Q11. Classify the following into rectilinear, circular, or oscillatory motion: (a) a stone falling vertically, (b) the needle of a sewing machine, (c) Earth spinning on its axis, (d) a train on a straight track.
Q12. What is random motion? Give two examples from everyday life. Why is it difficult to predict the path of random motion?
Long Answer Questions
Q13. Describe any four types of motion with one clear example of each. For each type, also state whether the object's speed remains constant or changes, and whether the direction changes.
Q14. Explain with diagrams (or clear descriptions) the difference between
(a) rectilinear motion and curvilinear motion, and
(b) periodic motion and non-periodic motion. Give two real-life examples for each type.
Q15. A Kolkata tram runs on a straight track. A passenger inside the tram rolls a ball along the floor of the tram. A person standing on the road watches both the tram and the ball.
(a) What type of motion does the tram show?
(b) What type of motion does the ball show according to the passenger?
(c) What type of motion does the ball show according to the road-side observer?
(d) What conclusion can you draw about how reference frame affects the observed type of motion?
Application-Based Problems
Q16. A clock has three hands — hours, minutes, and seconds.
(a) What type of motion does each hand exhibit?
(b) If the minute hand is 5 cm long, describe the path traced by its tip in 60 minutes.
(c) Is the tip of the minute hand in periodic motion? Justify.
Q17. Identify and justify the type(s) of motion for each of the following:
(a) A rubber ball bouncing repeatedly on the floor.
(b) A satellite orbiting Earth.
(c) A piston moving inside a car engine.
(d) Smoke particles rising from an incense stick (agarbatti).
(e) A child sliding down a straight slide in a park.
Q18. Design a simple observation activity: Choose any three objects around your house. For each object, (a) describe its motion, (b) classify the type of motion, and (c) explain what would change about the motion if you changed the reference point of observation.
