What is circular motion? What is the concept of centre of mass? What are kinematical equations of motion? Do you know real and pseudo forces, their origin and applications?
Understand the Problem
The question is asking for explanations about various concepts related to circular motion and rotational dynamics, including definitions of terms and equations related to motion.
Answer
Circular motion: circular path. Center of mass: average position. Kinematics: motion equations. Real forces are natural; pseudo forces in non-inertial frames.
Circular motion involves an object moving along a circular path with constant or varying speed. The center of mass is the average position of all parts within a system. Kinematical equations describe motion in terms of displacement, velocity, and acceleration. Real forces arise naturally, while pseudo forces appear in non-inertial frames, like centrifugal force.

Circular motion involves an object moving along a circular path with constant or varying speed. The center of mass is the average position of all parts within a system. Kinematical equations describe motion in terms of displacement, velocity, and acceleration. Real forces arise naturally, while pseudo forces appear in non-inertial frames, like centrifugal force.
More Information
Circular motion can be uniform, with constant speed, or non-uniform, with changing speed. The center of mass helps simplify the analysis of motion and interactions. Real forces are interactions like gravity or tension; pseudo forces arise when viewing motion from accelerating frames, explaining phenomena like centrifugal effects.
Tips
Confusing real forces with pseudo forces is common; remember that pseudo forces don't exist in an inertial frame.
