Question

The motion of a butterfly can be described as
(A) Periodic motion
(B) Circular motion
(C) Translatory motion
(D) Random motion

Answer 1

Hint : Hint: In this question, we are required to describe the motion of the butterfly, and to do that we will first define all given options.

Complete step by step answer:
To explain the motion of a butterfly, we will first define all the four options given in the question.
Periodic motion, in physics, is described as motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.
Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with the constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
When an object moves from one place to another place concerning the frame to reference, then this motion is said to be a translatory motion.
Random motion is an unpredictable kind of motion where an object moves in any direction and the direction keeps changing continuously.
Butterflies use their wings for many purposes: for flight, and to create camouflage patterns. Butterfly’s erratic flight is an evolutionary tactic that makes it harder for any would-be predators to predict the insect’s flight path. So by this theory, we can conclude that the motion of a butterfly is random.
In random motion, the flight direction and speed are continuously changed. Since the wings of a butterfly are attached to the thorax, it rotates the body to control the direction during the flapping flight. Depending upon the motion of the body, the flight modes can be different in a butterfly. The motion is useful for a butterfly since it helps to escape from enemies.

Hence the motion of a butterfly is described as a random motion as it does not move in a defined path.

Note: To solve this kind we should know motion along with its types and properties. Motion is the action or process of moving or of changing place or position, also describing it as a change with time of the position or orientation of a body.
