This section delves into the principles of motion, equilibrium, and moments, providing detailed explanations of uniform acceleration and the conditions for equilibrium in physical systems.
Definition Objects in equilibrium are either at rest or moving at constant velocity, with the sum of forces equal to zero.
Example A detailed analysis of a stone dropped from a bridge demonstrates the application of SUVAT equations in calculating final velocity and time of fall.
Highlight The principle of moments states that for an object in equilibrium, the sum of clockwise moments equals the sum of anticlockwise moments about any pivot point.
Vocabulary Couples are defined as pairs of coplanar forces equal in magnitude but acting in opposite directions.
Quote "For an object in equilibrium, the sum of anticlockwise moments about a pivot is equal to the sum of clockwise moments."
This section introduces the fundamental concepts of scalars and vectors in physics, providing essential definitions and practical applications. The content explores various methods of vector manipulation and problem-solving techniques.
Definition Scalars are quantities that only have magnitude, while vectors have both magnitude and direction.
Example A practical application of adding vectors using scale method is demonstrated through a ship navigation problem, where a vessel travels 30m at a bearing of 60°, followed by 20m.
Vocabulary Key terms include displacement, velocity, weight, force, and acceleration as vector quantities, while distance, mass, and speed are scalar quantities.
Highlight The section emphasizes the importance of trigonometry in resolving vectors, particularly when dealing with components parallel and perpendicular to a plane.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
