Theme A: Space, Time and Motion
This chapter covers the fundamental principles of motion in physics, including kinematics, forces, and momentum, with an emphasis on classical mechanics. It explores how to quantitatively describe motion and the impacts of applied forces on moving objects, culminating in a discussion of energy transformations and the concepts of work and power. Higher-level discussions also introduce rigid body mechanics and the implications of relativity at high speeds.

What we have learnt
- Kinematics describes the motion of objects through concepts of position, velocity, and acceleration.
- Newton's laws explain the relationship between force and motion, with a focus on free-body diagrams and momentum conservation.
- Understanding energy and work is crucial in analyzing how forces affect motion and in applying the work-energy principle.
Key Concepts
- -- Kinematics
- The branch of physics that deals with the motion of objects without considering the forces that cause the motion.
- -- Newton's Laws of Motion
- Three fundamental laws formulated by Sir Isaac Newton that describe the relationship between the motion of an object and the forces acting on it.
- -- Momentum
- The quantity of motion an object possesses, which is the product of its mass and velocity.
- -- Energy
- The capacity to do work, existing in various forms such as kinetic and potential energy.
