VCE Physics Resources - Unit 3 AoS 1 Motion. Cheat Sheet, Formula Sheet and AOS Summary Notes
Confused by kinematics? Struggling to apply Newton’s laws? Not sure which equation to use? We've got you covered.
"Truth is ever to be found in simplicity, and not in the multiplicity and confusion of things." – Isaac Newton
If Unit 3 Motion feels overwhelming, take Newton’s advice—truth lies in simplicity. We've stripped away the confusion to give you exactly what you need: clear explanations, a powerful formula sheet, and a concise summary to make mastering motion easier than ever.
Introduction to VCE Physics U3A1 - Motion
Understanding motion is essential to understanding how objects move and interact in our world. This introduction covers the key concepts that form the foundation of motion, from Newton's laws of motion to projectile motion and circular motion. For example, Newton's second law Fnet = ma describes how the net force acting on an object is directly proportional to its acceleration and inversely proportional to its mass. This relationship is fundamental in analysing how forces affect the motion of objects.
We also dive into the principles of momentum and impulse, showing how these concepts govern changes in velocity and forces during collisions. Additionally, we explore how energy transformations occur in systems, such as the conversion between kinetic and potential energy during vertical motion.
This resource helps you link the mathematical equations with real-world scenarios, preparing you to tackle problems in projectile motion and circular motion, where forces and energy interact in unique ways.

Summary of U3A1 - Motion
This summary covers all the essential concepts of motion, from Newton's laws to energy transformations. One example is vertical circular motion, where the forces at different points in the motion are explored. For instance, at the highest point, the net force is the difference between gravitational and normal forces, making the object feel lighter. At the lowest point, the normal force is greater than the gravitational force, causing the object to feel heavier. Understanding these forces is crucial for solving motion-related problems in real-world scenarios.
The image below is just one example of the detailed diagrams included in the summary, which help you visualise complex concepts and break them down step-by-step.

Formula Sheet of U3A1 - Motion
This formula sheet is a key tool for mastering the essential concepts in Unit 3, Area of Study 1. Take, for example, the formula for the range of a projectile with a symmetrical trajectory:
...where R is the range (horizontal displacement), u is the initial velocity, θ is the angle of firing above the horizontal, and g is the acceleration due to gravity. This formula helps you calculate the horizontal distance a projectile travels when launched at an angle, assuming no air resistance and a symmetrical trajectory.
The sheet includes equations beyond the VCAA's formula sheet and provides brief notes on certain formulas, explaining their use where needed - and thus ensuring that you have both the necessary equations and the context for applying them effectively.
