Motion is an object's change in position over time. Acceleration, speed, and velocity are used to describe motion. Forces like friction and gravity influence the way things move. Understanding motion enables us to comprehend commonplace phenomena like rolling balls and automobiles.

In this topic, we learn about the physical concepts of work done, energy, and power, exploring how force applied over a distance accomplishes work, how energy is defined and measured in various forms, and how power represents the rate at which energy is transferred or converted, providing insights into fundamental principles of physics that underlie many everyday phenomena.

This topic is about the force that affects everything around us, from tiny objects to big things. We will see how this force acts everywhere and helps us understand how things move, change, or stay in place in our daily lives and in nature.
