Notes Topic.2.2 Properties of electromagnetic waves 1 (AQA gcse Physics 2, paper 2, Topic 6 "Forces ( HT only ) Know that different substances may absorb, transmit, refract or reflect electromagnetic waves. Throughout this section on forces and motion you should be able to use ratios and proportional reasoning to convert units and to compute rates. ( HT only ) A knowledge of the detailed structure of the ear is not required. You should be able to describe the similarities and distinctions between the planets, their moons, and artificial satellites. Topic.3.4 Transformers ( HT only ) (AQA gcse Physics 2, paper 2, Topic 7 "Magnetism and electromagnetism Know that a basic transformer consists of a primary coil and a secondary coil wound on an iron core. The atmosphere gets less dense with increasing altitude. You should be able to recall the factors that affect the size of the induced potential difference/induced current recall the factors that affect the direction of the induced potential difference/induced current apply the principles of the generator effect in a given context. If all wavelengths are reflected equally the object appears white. Colour filters work by absorbing certain wavelengths (and colour) and transmitting other wavelengths (and colour). You should be able to calculate relevant values of stored energy exam
and energy transfers. You should have had the opportunity to make observations of waves in fluids in order to identify the suitability of apparatus to measure speed, frequency and wavelength. Link for, aQA 9-1, gCSE physics 1, paper. The Earth has a magnetic field. The extension of an elastic object, such as a spring, is directly proportional to the force applied, provided that the limit of proportionality is not exceeded. Gravity provides the force that allows planets and satellites (both natural and artificial) to maintain their circular orbits. You should be able to describe the difference between longitudinal and transverse waves. And in a dynamo to generate.c. Topic.5.1.2 Pressure in a fluid 2 (HT only) (AQA gcse Physics 2, paper 2, Topic 5 "Forces Know that the pressure due to a column of liquid can be calculated using the equation: pressure height of the column density of the liquid gravitational field. Your own lesson/revision notes and textbooks for. The direction of a magnetic field line is from the north (seeking) pole of a magnet to the south (seeking) pole of the magnet. This allows ultrasound waves to be used for both medical and industrial imaging. Topic 8 Space physics (AQA gcse Physics 2, paper 2, Topic 8 "Space physics Questions about where we are, and where we came from, have been asked for thousands of years. Fusion processes in stars produce all of the naturally occurring elements. This restricts the limits of human hearing. contact forces and non-contact forces, scalar and vector quantities Revision Notes Topic.1.3 Gravity (AQA gcse Physics 2, paper 2, Topic 5 "Forces Know that weight is the force acting on an object due to gravity. You should be able to explain safety features such as: air bags, seat belts, gymnasium crash mats, cycle helmets and cushioned surfaces for playgrounds with reference to the concept of rate of change of momentum. This is limited to simple evidence such as air does not move away from a vibrating tuning fork to create a vacuum.
J 4 Uses and applications, in newtons, w F s work done. Typical values range from, you should be able to calculate papers the resultant of two forces that act in a straight line. N Reflection from a rough surface causes scattering this is called diffuse reflection.

The strength of the magnetic field depends on the distance from the magnet. The speed of an object can be calculated from the gradient of its distancetime graph. Paper 2, that all depends on you and the factors mentioned in point. Waves can be absorbed or transmitted at the boundary between two different materials. Or its distance from a pivot. Acting on an object that is balanced. Topic, for ALL other exam papers, topic 7" HT only The distance travelled by an object or displacement of an object can be calculated from the area under a velocitytime graph. I know from feedback that my gcse science summary revision pages have proved useful but they do not guarantee a high grade 3, specimen practice question papers AQA gcse Grade 91 Physics Foundation Tier papers FT AQA gcse Grade 91 Physics Foundation Tier papers. You should be able to express a displacement in terms of both the magnitude and direction. Magnetism and electromagnetism Microphones use the generator effect to convert the pressure variations in sound examples of scoring rubrics for student papers waves into variations in current in electrical circuits.
The turning effect of a force is called the moment of the force.You should be able to construct ray diagrams for both convex and concave lenses.Since a good absorber is also a good emitter, a perfect black body would be the best possible emitter.
