Since the force between a charge Q and a small charge q placed with the field of Q is given by , it follows that: KEY POINT - The electric field strength, E, due to a point charge Q is given by the expression: In a radial field, the field strength follows an inverse square law. Updates. When drawing field lines that represent the forces due to a charged object, the arrows show the direction of the force on a positive charge.

Revision for CIE AS and A-level Physics (9702) papers, including summary notes, videos, factsheets and past exam questions by topic. When passing between the plates, the electrons have a constant speed in the direction parallel to the plates. Unlike the potential in the gravitational field of a point mass, the electric potential in the field of a point charge is positive, since work has to be done to move a positive charge from infinity to any point in the field. KEY POINT - When an electron is accelerated through a potential difference V it gains kinetic energy   where me is the mass of an electron and e is the electronic charge. The diagram shows the electric fields due to a point charge and between a pair of oppositely charged parallel plates.

A Level Physics Notes. electric field strength is defined as force per unit charge, gravitational field strength is defined as force per unit mass, electric potential and gravitational potential are defined in similar ways, the electric field due to a point charge is similar to the gravitational field of a point mass. These are free to download and to share with others provided credit is shown. The syllabus includes the main theoretical concepts which are fundamental to the subject, a section on some current applications of physics, and a strong emphasis on advanced practical skills. The beam is produced by an electron gun, a device that accelerates and focuses the electrons given off by a hot wire. In a radial field. them. Describe the electric field due to a point charge and between two charged parallel plates, calculate the force on a charge in an electric field and compare gravitational and electric fields. The specific latent heat of fusion ( Solid) / vapori­sation ( gas) is the quantity of thermal energy needed­/will be lost to change the state of 1kg of the substance.Q = ml where m is the mass and l the latent heat. The emphasis throughout […] Einstein's famous equation describes how energy, E, and mass, m are related, where c is the speed of light. A-level Physics Tutor - a free resource for aspiring physicists. Question 1: [Planning – 15 marks] Perpendicular to the plates, the force on each electron is equal to Ee, so they accelerate in this direction. 22 April 2020 : All content for Cambridge International AS and A Level Physics (9702) has been updated. The effect of this can be seen by studying the path of a beam of electrons in a deflection tube. Comparing electric and gravitational fields. Potential could be measured relative to the upper plate, in which case the potentials would have negative values. Water has a high permittivity due to its molecules being polarised. The diagram below shows an electron gun. Copyright © 2020 Mega Lecture Resources include A-Level Physics Revision Notes, A-Level Physics Help Forums (General Revision + Edexcel, AQA, OCR & WJEC), Exam Specs, Exam Papers, Physics Revision Guides (A Level) & More. You also need to know that the area under the line gives you the displacement of the object up to that point. and The Transformer. It is caused by electrons leaving one surface and joining another. Close. This results in objects having one of two types of charge: Electrostatic phenomena such as attraction and repulsion are due to the forces between two charged objects. After studying this section you should be able to: Transfer of charge happens whenever two objects in physical contact move relative to each other. A-Level Physics Revision section of StudyWise. Acceleration-time graphs Note: All three of the movement graphs are related to each other as the: Company Registration Number: 61965243, Stuvia is not sponsored or endorsed by any college or university, Essential Environment: The Science Behind the Stories, Everything's an Argument with 2016 MLA Update, Managerial Economics and Business Strategy, Primates of the World: An Illustrated Guide, The State of Texas: Government, Politics, and Policy. Here are Physics Notes for A Level (A2) chapter wise. This gives an alternative unit for electric field strength, V m–1, which is equivalent to the N C–1. That between the parallel plates is uniform, it maintains a constant strength at all points between the plates. Would love to travel a lot too broke to do that. When a substance changes state, there is a period where the temper­ature of the material is constant, as the internal energy rises, this is due to the latent heat.

This can be seen by the way in which the field lines spread out from a point charge. A charge q moving between the plates would gain or lose energy Vq. To make it easier for teachers to understand what's required, we have: 1. updated the learning outcomes, clarifying the depth to which each topic should be taught. 509 4443 Email: admin @ megalecture.com for students, by students topics below for notes and other revision.
