  • Mathematics provides a compact and exact language used to describe the order in nature. This was noted and advocated by Pythagoras,[49] Plato,[50] Galileo,[51] and Newton. Physics uses mathematics[52] to organise and formulate experimental results. From those results, precise or estimated solutions are obtained, quantitative results from which new predictions can be made and experimentally conf

Description

Classical physics includes the traditional branches and topics that were recognised and well-developed before the beginning of the 20th century—classical mechanicsacousticsopticsthermodynamics, and electromagnetismClassical mechanics is concerned with bodies acted on by forces and bodies in motion and may be divided into statics (study of the forces on a body or bodies not subject to an acceleration), kinematics (study of motion without regard to its causes), and dynamics (study of motion and the forces that affect it); mechanics may also be divided into solid mechanics and fluid mechanics (known together as continuum mechanics), the latter include such branches as hydrostaticshydrodynamicsaerodynamics, and pneumatics. Acoustics is the study of how sound is produced, controlled, transmitted and received.[44] Important modern branches of acoustics include ultrasonics, the study of sound waves of very high frequency beyond the range of human hearing; bioacoustics, the physics of animal calls and hearing,[45] and electroacoustics, the manipulation of audible sound waves using electronics.

Distance and displacement

What is Distance?

Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.

How is Displacement defined?

Displacement is defined as the change in position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position. For Example- If an object moves from A position to B, then the object’s position changes. This change in position of an object is known as Displacement.
