When an object repeats its motion over the same path after equal interval of time, it is called periodic motion. For example, the motion of wheel, motion of the clock, motion of the Earth, motion of the Simple Pendulum, etc. The back and forth periodic motion is called oscillatory motion. For example, the motion of wheel is periodic, but not oscillatory. The motion of simple pendulum is periodic as well as oscillatory. Thanks 😊😊😊
Tbh the lecture lacked one rotational motion. The motion of earth or tops (Beyblades) spinning around their own central rotational axis. For example rotation of the earth that causes day and night (not revolution around the sun). As its name suggests this type of motion is called spinning motion.
Random motion is not a sub type of translatory motion because not all the particles of random motion do translate e.g motion of a smoke. Secondly, motion of a body along the circumference of a circle is circular motion not rotatory motion. In rotatory, the axis of rotation must pass through the object. For instance, The motion of a fan is rotatory motion but the motion of the fan blade is circular motion because the axis of rotation is not passing through the blade but the body of the fan.
Well, if an object move around its own center or axis, it is considered as spin motion. So, the Earth spin around its own axis and completes one spin motion in 24 hours. Now, if an object moves around an externel center or axis on a circular path, it is considered as rotatory motion. For example, the Earth rotates around the Sun (although, the eartg doesn't move on a fixed circular path, but it moves on elliptical path). So, the Earth completes one rotation around the sun in one year. I hope you understand it. Thanks!!! 🙏🙏🙏🙏🙏
No periodic motion means that repeats itself in equal intervals of time whereas vibratory motion means when a streched object is pulled and released it vibrates Hope you understood
Sir tanslatory motion means a body move uniformly in the same direction and line but in random motion - the direction of body is not fixed So why we say that random motion is a part of tanslatory motion 🤔
Congratulations!!! I am more happy than you for your this achievement. By God, after reading your comment; a layer of happiness triggered in my whole body... and I said YESSSSSS!!! Because I love... I love my students... Please, please, feel fre to ask me whenever you face any problem... Wish you God speed!!!😂😂😂😂😂😂😂😂😂😂😂😂😂😂
Lol “is a” took me a while to understand he said “a” well......if the captions wasn’t on I wouldn’t have understood it at all No offense.......I guess you have a different English accent I guess South Indian accent
Translatory motion is type of motion in which body translate it while rectilinear motion is a type of translatory motion. When a car moves on a straight road, it is in translatory motion, but at the same time it is in rectilinear motion. Feel free to ask more if you don't understand... Thanks!
Yes, both oscillatory and vibratory motion are back and forth or up and down motion. (Although there is slightly difference between oscillatory and vibratory motion of frequencies which you can learn from my video on: "Difference between oscillatory and vibratory motion".) Thanks!!! 🙏🙏🙏🙏🙏
Oscillatory and periodic motions are same as vibratory motion... Also, we have a separate tutorial on oscillatory motion.... Watch that tutorial... 😊😊😊
Sir, rotatory motion is that type of motion in which a body moves around a fixed axis but the axis is in the body not outside the body so the motion of Earth around the Sun is actually curvilinear motion not rotatory motion.
