Questions with solutions
Q1 — Random & Oscillatory Motion · easy · theory
Motion of an object moving to and fro about a fixed point is called:
A. Rectilinear motion
B. Oscillatory motion ✓ Correct
C. Random motion
D. Circular motion
Solution: To-and-fro motion about a fixed point is called oscillatory motion.
Q2 — Random & Oscillatory Motion · easy · theory
Irregular motion with no fixed path or direction is called:
A. Circular motion
B. Random motion ✓ Correct
C. Oscillatory motion
D. Periodic motion
Solution: Random motion has no fixed path and keeps changing direction.
Q3 — Random & Oscillatory Motion · easy · theory
Which of these is an example of oscillatory motion?
A. A car on a straight road
B. A spinning fan
C. A rolling marble
D. A swing moving back and forth ✓ Correct
Solution: A swing moves to and fro about a fixed point, which is oscillatory motion.
Q4 — Random & Oscillatory Motion · easy · theory
Which of these is an example of random motion?
A. A pendulum in a clock
B. A guitar string vibrating
C. A swing being pushed
D. A butterfly flying in a garden ✓ Correct
Solution: A butterfly changes direction irregularly, so it shows random motion.
Q5 — Random & Oscillatory Motion · medium · theory
A football player running here and there during a match shows which type of motion?
A. Random motion ✓ Correct
B. Periodic motion
C. Oscillatory motion
D. Circular motion
Solution: The player’s path keeps changing with no fixed pattern, so it is random motion.
Q6 — Random & Oscillatory Motion · medium · theory
The to-and-fro movement of a sitar (or guitar) string when it is played is:
A. Oscillatory motion ✓ Correct
B. Rectilinear motion
C. Random motion
D. Rotational motion
Solution: The string vibrates to and fro about its rest position, which is oscillatory motion.
Q7 — Random & Oscillatory Motion · medium · theory
Which pair correctly matches each object with its motion?
A. Both are random
B. Both are oscillatory
C. Swing → random, Housefly → oscillatory
D. Swing → oscillatory, Housefly → random ✓ Correct
Solution: A swing moves to and fro (oscillatory), while a housefly moves irregularly (random).
Q8 — Random & Oscillatory Motion · medium · theory
Tiny dust particles seen dancing in a beam of sunlight move in:
A. Oscillatory motion
B. Rectilinear motion
C. Random motion ✓ Correct
D. Circular motion
Solution: The dust particles move irregularly in all directions, showing random motion.
Q9 — Random & Oscillatory Motion · hard · theory
Which of these is oscillatory but NOT random?
A. A bird flying freely in the sky
B. Children running in a playground
C. A pendulum swinging back and forth ✓ Correct
D. A mosquito buzzing about
Solution: A pendulum has a regular to-and-fro path (oscillatory); the others move irregularly (random).
Q10 — Random & Oscillatory Motion · hard · theory
Why is the swinging of a swing called oscillatory, while the flight of a bee is called random?
A. The swing moves to and fro about a fixed point, but the bee has no fixed path ✓ Correct
B. The bee moves to and fro
C. Both of them move in circles
D. The swing has no fixed path
Solution: Oscillatory motion is a regular to-and-fro about a point, while random motion has no fixed path.
