Questions with solutions
Q1 — Periodic & Non-periodic Motion · easy · theory
Motion that repeats itself after a fixed interval of time is called:
A. Random motion
B. Straight-line motion
C. Periodic motion ✓ Correct
D. Non-periodic motion
Solution: Periodic motion repeats again and again after a fixed time interval.
Q2 — Periodic & Non-periodic Motion · easy · theory
Which of these is an example of periodic motion?
A. A car stuck in traffic
B. A leaf falling in the wind
C. The swinging of a pendulum ✓ Correct
D. A butterfly flying about
Solution: A pendulum repeats its swing after a fixed time, so it is periodic motion.
Q3 — Periodic & Non-periodic Motion · easy · theory
The beating of your heart is an example of:
A. Non-periodic motion
B. Random motion
C. Rectilinear motion
D. Periodic motion ✓ Correct
Solution: The heart beats again and again at regular intervals, so it is periodic motion.
Q4 — Periodic & Non-periodic Motion · easy · theory
Which of these is a non-periodic motion?
A. A bee flying here and there ✓ Correct
B. The hands of a clock
C. A swinging pendulum
D. A rotating Earth
Solution: A bee’s flight does not repeat at fixed intervals, so it is non-periodic motion.
Q5 — Periodic & Non-periodic Motion · medium · theory
The Earth takes 24 hours for one rotation, over and over again. This makes its rotation a:
A. Random motion
B. Rectilinear motion
C. Non-periodic motion
D. Periodic motion ✓ Correct
Solution: It repeats after a fixed time of 24 hours, so it is periodic motion.
Q6 — Periodic & Non-periodic Motion · medium · theory
Which of the following is NOT a periodic motion?
A. The pendulum of a wall clock
B. The needle of a working sewing machine
C. A cradle rocking at a steady rate
D. A flag fluttering in the wind ✓ Correct
Solution: A fluttering flag moves irregularly, not after a fixed time, so it is non-periodic.
Q7 — Periodic & Non-periodic Motion · medium · theory
The time taken to complete one full repeat of a periodic motion is called its:
A. Speed
B. Length
C. Time period ✓ Correct
D. Distance
Solution: One complete repetition of a periodic motion takes a fixed time called the time period.
Q8 — Periodic & Non-periodic Motion · medium · theory
Which statement about periodic motion is correct?
A. It has no fixed pattern
B. It always moves in a straight line
C. It repeats after equal intervals of time ✓ Correct
D. It never repeats itself
Solution: Periodic motion repeats after equal (fixed) time intervals.
Q9 — Periodic & Non-periodic Motion · hard · theory
The moon revolves around the Earth in about 27 days each time. Its revolution is periodic because:
A. It repeats after the same fixed time ✓ Correct
B. It never comes back
C. It moves in an irregular way
D. It moves in a straight line
Solution: A motion is periodic when it repeats after a fixed time, as the moon does.
Q10 — Periodic & Non-periodic Motion · hard · theory
Consider: (i) sunrise every morning, and (ii) a kite moving here and there in the sky. Which is correct?
A. (i) is periodic and (ii) is non-periodic ✓ Correct
B. (i) is non-periodic and (ii) is periodic
C. Both are periodic
D. Both are non-periodic
Solution: Sunrise repeats at fixed times (periodic), while a kite’s path is irregular (non-periodic).
