Question

Statement 1: Rest and motion changes for an object with respect to the point of view or reference frame.
Statement 2: The blades of the switched on table fan follows rotational motion.

Which of the following is correct?

• A. Statement 1 is true but statement 2 is false.
• B. Statement 1 is false but statement 2 is true.
• C. Both the statements are true.
• D. Both the statements are false.

Answer 1

The correct option is C Both the statements are true.

Rest and motion changes for an object with respect to the point of view or reference frame.
For example- For a person travelling in a bus, to him all other passengers including him are at rest with bus as the frame of reference.
However for a person who's outside the bus, sees everyone inside the bus in motion.

The motion of objects such that all its points are in a circular path about a point is known as rotational motion. In the case of the switched on table fan, the blades of the fan follow rotational motion.
