1. Motion of a ceiling fan is an example of:
Answer: d) Both b and c
A ceiling fan rotates in a circular path and repeats its motion after equal intervals of time. Hence, it shows both circular and periodic motion.
A ceiling fan rotates in a circular path and repeats its motion after equal intervals of time. Hence, it shows both circular and periodic motion.
2. Motion along a straight line is called:
Answer: c) Rectilinear motion
When an object moves in a straight path, its motion is called rectilinear motion. Example: A car moving on a straight road.
When an object moves in a straight path, its motion is called rectilinear motion. Example: A car moving on a straight road.
3. Motion of a pendulum is:
Answer: d) Both b and c
A pendulum repeats motion at equal intervals (periodic) and moves to and fro about a mean position (oscillatory).
A pendulum repeats motion at equal intervals (periodic) and moves to and fro about a mean position (oscillatory).
4. Earth’s rotation on its axis shows:
Answer: d) All of these
The Earth rotates about its axis (rotational), follows a circular path, and repeats every 24 hours (periodic).
The Earth rotates about its axis (rotational), follows a circular path, and repeats every 24 hours (periodic).
5. Motion of a swing is an example of:
Answer: a) Oscillatory motion
A swing moves to and fro about a central position repeatedly, which defines oscillatory motion.
A swing moves to and fro about a central position repeatedly, which defines oscillatory motion.
6. A car moving around a roundabout shows:
Answer: a) Circular motion
The car follows a circular path around the roundabout.
