    Introduction Sound waves are mechanical waves that propagate through a medium (like air, water, or solids) as a result of vibrations, creating pressure variations that the human ear detects as sound. They are longitudinal waves, where the oscillations occur in the direction of wave propagation. Speed of Sound The speed of sound varies depending on…

    Introduction Speed is a fundamental concept in physics that describes how quickly an object moves. It is a scalar quantity, meaning it has magnitude but no direction. The SI unit of speed is the meter per second (). Velocity, is speed plus some direction. Velocity is a vector quantity. Average and Instantaneous Speed Average speed…

    12.1 Introduction to Uniform Circular Motion (UCM) Uniform circular motion describes the movement of an object traveling in a circular path with a constant speed. Although the speed remains constant, the object experiences acceleration due to the continuous change in its direction. This page will explore the basics of uniform circular motion. 12.2 Defining Uniform…
