Answer:
1.Hint:Periodic motion is the type of motion which repeats its path after a specific time interval. Non periodic motion is a random kind of motion and it not necessarily repeats its path and can move at any path and not a designated one. We will use different examples to explain the difference between these motions.
2.Standard units are the units used all over the world for measuring a particular quantity. The need of a standard unit arises when we deal with people when from other places. This is because the unit used in that place may not be used by you and you might not be familiar with it.
3. All oscillatory motions are periodic because each oscillations gets completed in a definite interval of time. Eg: On being pulled and then released, a load attached to a spring executes oscillatory motion. On the other hand, all periodic motions may not be oscillatory.
4.The two examples of the Oscillatory motion are: Pendulum of clock Motion of a child on a swing
Pendulum of clock.
Motion of a child on a swing.
5.Measurement is the quantification of attributes of an object or event, which can be used to compare with other objects or events. ... The science of measurement is pursued in the field of metrology. Measurement is defined as the process of comparison of an unknown quantity with a known or standard quantity.
