- [Revision: Vectors, Velocity and Acceleration](https://www.hlayiso.com/grade-12/physical-sciences/notes/newtons-laws-and-forces/revision-vectors-velocity-and-acceleration) — Revision: Vectors, Velocity and Acceleration Before tackling Newton's Laws, you need a solid understanding of the fundamental physics concepts that underpin mechanics. This revision section brings…
- [Forces and Types of Forces](https://www.hlayiso.com/grade-12/physical-sciences/notes/newtons-laws-and-forces/forces-and-types-of-forces) — Forces and Types of Forces A force is a push or a pull that one object exerts on another. Forces are responsible for every change in motion you observe: a ball being kicked, a car braking, a book…
- [Force Diagrams and Resultant Forces](https://www.hlayiso.com/grade-12/physical-sciences/notes/newtons-laws-and-forces/force-diagrams-and-resultant-forces) — Force Diagrams and Resultant Forces Before applying Newton's laws to solve any problem, you must be able to correctly identify every force acting on an object and represent these forces in a clear…
- [Newton's First Law of Motion (Law of Inertia)](https://www.hlayiso.com/grade-12/physical-sciences/notes/newtons-laws-and-forces/newtons-first-law-of-motion-law-of-inertia) — Newton's First Law of Motion (Law of Inertia) Have you ever noticed how a box in the boot of a car slides forward when the car brakes suddenly? Or how passengers lurch sideways when a taxi turns a…
- [Newton's Second Law of Motion](https://www.hlayiso.com/grade-12/physical-sciences/notes/newtons-laws-and-forces/newtons-second-law-of-motion) — Newton's Second Law of Motion Newton's First Law tells us what happens when no net force acts on an object. But what happens when a net force does act? Newton's Second Law of Motion answers this…
- [Newton's Third Law of Motion](https://www.hlayiso.com/grade-12/physical-sciences/notes/newtons-laws-and-forces/newtons-third-law-of-motion) — Newton's Third Law of Motion Newton's Third Law is often quoted as "every action has an equal and opposite reaction." While this is easy to remember, it is frequently misunderstood. This law…
- [Newton's Law of Universal Gravitation, Mass and Weight](https://www.hlayiso.com/grade-12/physical-sciences/notes/newtons-laws-and-forces/newtons-law-of-universal-gravitation-mass-and-weight) — Newton's Law of Universal Gravitation, Mass and Weight Newton realised that the same force that causes an apple to fall from a tree also keeps the Moon in orbit around the Earth and the planets in…
- [Newton's Laws and Forces](https://www.hlayiso.com/grade-12/physical-sciences/notes/newtons-laws-and-forces/newtons-laws-and-forces) — Newton's Laws and Forces The study of forces and motion forms the foundation of classical mechanics. Understanding how forces interact with objects allows you to predict and explain the motion of…
