CBSE Class 9 Science Notes: Sound Nature of Sound Waves Sound, at its core, is a form of energy that travels through a medium as vibrations. These vibrations are caused by the movement of particles in the medium, creating areas of compression (high pressure) and rarefaction (low pressure). Sound waves are **longitudinal waves**, meaning the

CBSE Class 9 Science Notes: Work and Energy **Work and Work Done by a Force** Let’s explore the fundamental concept of work in physics. Work, in a scientific sense, is done when a force causes an object to move a certain distance. It’s crucial to understand that not all applications of force result in work
