Which of the following is/are examples of linear motion?

To begin, grasp what linear motion is. The name itself has significance. Linear refers to the straightest path, while motion refers to displacement/momentum. A linear motion occurs when the body travels in a straight path. Recognize the many forms of motion. Determine which of the following instances is of linear motion based on the definition. Indicate the type of motion in the examples provided.
Linear motion is defined as:
A linear motion is one in which the body travels in a straight path.
The gas molecules in a container filled with gas move randomly and have no preset direction of motion. As a result, they move at random.

A stone falling from a specific height falls in a straight path, exhibiting linear motion.
Because the swing is attached to a fixed point, it moves in a curved route and is not a linear motion.
Because the clock hand revolves around the fixed point, it is not a linear motion. Periodic motion is represented by the movement of a clock hand.
The correct answer is b, which describes the motion of a stone falling from a specific height.

Hence, the correct answer is option B.
