This page focuses on the principles of magnetism and electromagnetism, providing a detailed magnetism mind map for students. It covers the fundamental concepts of magnetic fields, types of magnets, and the rules governing magnetic interactions.
Definition: A magnetic field is a region where a force acts on another magnet or magnetic material.
The page explains the difference between permanent magnets and induced magnets, highlighting their properties and behaviors.
Highlight: Permanent magnets produce their own magnetic field and cannot be turned on or off, while induced magnets only become magnetic when placed in a magnetic field.
The concept of electromagnetism is introduced, with a focus on solenoids and electromagnets. The page describes how to create and strengthen electromagnetic fields.
Example: A solenoid with an iron core forms an electromagnet, which can be used in devices such as relays.
The relationship between electricity and magnetism is explored, including the magnetic field around current-carrying wires.
Vocabulary: A solenoid consists of a wire coiled into a spiral shape, creating a magnetic field similar to that of a bar magnet when an electric current flows through it.
This section provides valuable insights for students studying magnetism and electromagnetism at various levels, including those preparing for A level Physics examinations.
This page covers key concepts related to elasticity, forces, and energy in physics. It begins with an exploration of force-extension relationships, including Hooke's Law and the elastic limit of materials.
Definition: The elastic limit refers to the point beyond which a material's deformation becomes permanent and Hooke's Law no longer applies.
The page distinguishes between contact and non-contact forces, providing examples of each type.
Example: Magnetic force is a non-contact force, while friction is a contact force.
Scalar and vector quantities are explained, emphasizing the difference between quantities that have only magnitude and those that have both magnitude and direction.
Vocabulary: Vector quantities have both magnitude and an associated direction, while scalar quantities only have magnitude or size.
The concept of work done is introduced, along with its relationship to energy transfer.
Highlight: Work done occurs when energy is transmitted from one store to another and can be calculated as the product of force and distance.
The page concludes with a discussion on energy storage in springs, introducing the concept of elastic potential energy.
Example: The elastic potential energy stored in a spring can be calculated using the formula: 0.5 × spring constant × (extension)².
This comprehensive overview provides essential information for students studying Physics notes on amplitude and wavelength concepts and preparing for exams in mechanics and energy.
This page covers fundamental concepts related to waves and the electromagnetic spectrum. It explores key properties of waves such as amplitude, wavelength, and frequency. The page also delves into different types of waves including transverse and longitudinal waves.
Definition: Amplitude is the maximum displacement from the equilibrium position, measured as half the height of a wave in meters.
Vocabulary: Wavelength refers to the distance between two points on a wave, representing the length of one complete cycle measured in meters.
The page provides information on wave speed calculations and compares the speed of light in a vacuum to the speed of sound in air. It also examines the properties of electromagnetic waves and their various applications.
Highlight: Electromagnetic waves cause oscillations in electrical and magnetic fields, while mechanical waves require a medium and cause particle oscillations.
The electromagnetic spectrum is presented, ranging from radio waves to gamma rays, with notes on their respective uses and potential hazards.
Example: Microwaves are used for cooking food and satellite communications, while ultraviolet rays can have damaging effects on the human body.
This comprehensive overview serves as an excellent resource for students studying IGCSE physics waves or preparing for O level physics waves examinations.

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.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

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.
