are due to the difference in velocity of the waves in different substances. The theoretical calculations of Bohr agreed with experimental observations. The greater the resistance of the component the smaller the current for a given potential difference (pd) across the component. Topic.1 Forces and their interactions (revision notes summary for AQA 9-1 gcse Combined Science Trilogy: Physics Paper 6, Topic 22 "Forces Topic.1.1 Scalar and vector quantities Know that scalar quantities have magnitude only. Topic 23 Waves (revision notes summary for AQA 9-1 gcse Combined Science Trilogy: Physics Paper 6, Topic 23 "Waves Wave behaviour is common in both natural and man-made systems. The wave speed is the speed at which the energy is transferred (or the wave moves) through the medium. Electromagnetic radiation Radio waves Microwaves Infrared radiation Visible light Ultraviolet light X-rays Gamma rays Energy increasing energy of radiation (J) Frequency increasing frequency of radiation (Hz) Wavelength decreasing wavelength of radiation (m) 'picture trend' Our eyes essay detect visible light and so only detect a limited. ( HT only ) You should be able to: describe examples of the forces acting on an isolated object or system use free body diagrams to describe qualitatively examples where several forces lead to a resultant force on an object, including balanced forces when the. ( HT only ) You should be able to give brief explanations why each type of electromagnetic wave is suitable for the practical application. The frequency of a wave is the number of waves passing a point each second. This is awesome, cheers. Paper 1 Physics - Foundation (8463/1F). The wavelength of a wave is the distance from a point on one wave to the equivalent point on the adjacent wave. Internal energy is the total kinetic energy and potential energy of all the particles (atoms and molecules) that make up a system. As a result, the current flowing through a filament lamp is not directly proportional to the voltage across.

You should be able to use the concept of momentum as a model to describe examples of momentum in an event such as a collision You should have investigated collisions between laboratory trollies using light gates, data loggers or ticker timers to measure and record. Mass gravitational field strength height, Ep m g h gravitational potential energy (gpe Ep, in joules, J mass, m, in kilograms, kg; gravitational field strength, g, in newtons per kilogram, N/kg height, h, in metres, m (In any calculation the value of the gravitational field. Mains to the kinetic energy of electric motors or the energy of heating devices. You should be able to recognise expressions given in standard form.

Energy transferred power time, e P t energy transferred charge flow potential difference. You may be required to calculate or use efficiency values as a decimal or as a percentage above x 100. In watts, in joules, it is not only moving objects that have varying speed.

W In seconds, how did they find out there were three types of atomicionising radiation.
Eventually the resultant force will be zero and the object will move at its terminal velocity.Vpotential difference where is a voltmeter placed in a circuit and what does it measure?The half-life of a radioactive isotope is the average time it takes for the number of nuclei of the isotope in a sample to halve, or the average time it takes for the count rate (or activity) from a sample containing the isotope to fall.
