Circular Motion is a branch of physics that deals with the study of objects in motion that follows a circular path. It covers topics such as the forces acting on an object in circular motion, the angular velocity and acceleration of an object, and the conservation of energy and momentum in a
Circular economy (CE), or circularity, is a model of resource production and consumption that involves sharing, leasing, reusing, repairing, refurbishing, and recycling materials and products, to extend product life cycle for as long as possible. The concept aims to tackle global challenges such as climate change, biodiversity loss, waste, and pollution by emphasizing the design-based implementation of the three base principles of the model. The main three principles required for the transformation to a circular economy are:designing out waste and pollution, keeping products and materials in use, and regenerating natural systems.
