Also learn the methods of reducing heat transfers in the home and the human body. 2 WJEC GCSE Physics P2 Higher Tier Summer 2010 Q4 3 Figure 1.13 shows an ammeter A and a voltmeter V connected to a power supply and a resistance wire XY. Our books simplify key GCSE topics into bitesize chunks of information to improve students' understanding and boost confidence. Revise the types of heat transfer including convection and radiation. Designed to engage learners and make Physics accessible to all learners, Pocket Posters are the perfect alternative to larger text-heavy revision guides and textbooks that can often disengage students.

In a ray diagram, a concave lens is drawn as a vertical line with inward facing arrows to indicate the shape of the lens.Physics GCSE Revision Guides are colourful and engaging learning aids that provide students with all the key content they need to excel in GCSE Physics. GCSE Physics Revision with Jonas provides you with easy-to-follow theory and examples. They separate but appear to come from a principle focus on the other side of the lens. Concave lensesĪ concave lens is thinner in the middle than it is at the edges. The distance from the lens to the principal focus is called the focal length. Struggling with Physics Find a one-to-one tutor on our new Tuition Platform. In a ray diagram, a convex lens is drawn as a vertical line with outward facing arrows to indicate the shape of the lens. Physics Revision Approaching end of year exams Want to recap everything you learnt in Year 12 Check out our online May Half-term AS-level Physics Recap Course for AQA and OCR (A) on 30-31st May. They come together at a point called the principal focus. Students also use the videos during their own study/revision as their. Parallel light rays that enter the lens converge. The number one place for you to find everything you need to master GCSE Physics. Convex lensesĪ convex lens is thicker in the middle than it is at the edges. Lenses are used in cameras, telescopes, binoculars, microscopes and corrective glasses. Scalar and vector quantities are treated differently in calculations. It cannot be created or destroyed but it can be transferred, dissipated or stored in different ways. The physical quantities they measure fall into two categories: scalars and vectors. When light is refracted it changes direction due to the change in density as it moves from air into glass or plastic. GCSE AQA Changes in energy stores Energy can be described as being in different ‘stores’. Jonny Nelson introduces an animated explanation of lensesĪ lens is a shaped piece of transparent glass or plastic that refracts light.
