Emit - GCSE Physics Definition

In the context of GCSE Physics, 'emit' refers to the process by which an object or substance gives off energy in the form of particles or waves. This energy can be in various forms, such as light, heat, or sound. For example, the Sun emits light and heat, which travel through space and are essential for life on Earth. Emission is a fundamental concept in understanding how energy is transferred and transformed in different physical processes. Understanding the way materials emit energy can help students grasp important topics such as radiation, the behaviour of waves, and the principles of thermodynamics.
