Chapter 1: Units and Measurements

In order to measure physical quantities such as length, mass, and time, we need a standard measurement, which is known as the unit of that physical quantity. For example, the unit of length is metres. How many times this standard unit of length is contained within the length of the object is what is measured when finding the length of an object. A number accompanied by a unit expresses the result of a measurement of a physical quantity.

Chapter 2: Motion in a Straight Line

In Physics, motion is defined as the phenomenon in which an object experiences a shift in position over a particular period. Motion can be mathematically described in terms of several different factors, including displacement, distance, velocity, speed, acceleration, and time. Identifying the frame of reference to which an item is attached is necessary to observe motion. Motion is measured based on changes in the object's location about the frame of reference. In this chapter, we will learn about the motion of the objects in a straight line, it is also called rectilinear motion. See below the topics covered in the Chapter 2:

Oscillation is the repeated two-and-forth movement of an object between two positions or states. This type of motion is periodic, meaning it repeats itself in a regular cycle, as exemplified by a sine wave, the back-and-forth swing of a pendulum, or the up-and-down motion of a spring-loaded weight. The oscillation takes place around an equilibrium point or a mean value and is often referred to as periodic motion. A full oscillation is considered to occur when the object completes one cycle of motion, whether it is a side-to-side or up-and-down movement.
