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, includingbalanced forces when the. You should be able to explain: how, at the start of a star's life cycle, the dust and gas drawn together by gravity causes fusion reactions that fusion reactions lead to an equilibrium between the gravitational collapse of a star and the expansion. And in a dynamo to generate.c. Mass and the effect of gravity on it - weight, (mention of work done and GPE) Revision Notes Topic.1.4 Resultant forces Know that a number of forces acting on an object may be replaced by a single force that has the same effect. You should be able to describe: the attraction and repulsion between unlike and like poles for permanent magnets the difference between permanent and induced magnets. This is the basis of an electric motor. AQA gcse grade 9-1, combined Science, trilogy physics and double check your exam table aqa past papers science biology foundation core from school, college or academy. The number of air molecules (and so the weight of air) above a surface decreases as the height of the surface above ground level increases. Topic.2.3 Electric motors ( HT only ) A coil of wire carrying a current in a magnetic field tends to rotate. General introduction to the properties of waves, types of waves and their effects, wave calculations Revision Notes Sound waves - properties explained, uses of sound including ultrasound Revision Notes Topic.1.2 Properties of waves Know that waves are described by their amplitude, wavelength, frequency and. The size of the moment is defined by the equation: moment of a force force distance, M F d moment of a force, M, in newton-metres, Nm ; force, F, in newtons, N distance, d, is the perpendicular distance from the pivot to the line of action. 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 Be able to complete calculations involving an event, such as a collision of two objects. 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. Attraction and repulsion between two magnetic poles are examples of non-contact force. You should be able to explain how a moving-coil loudspeaker and headphones work. You should be aware that the study of seismic waves provided new evidence that led to discoveries about parts of the Earth which are not directly observable Sound waves - properties explained, uses of sound including ultrasound Revision Notes The Structure of the Earth, crust. Typical values range from.4 s.9. An alternating current in the primary coil of a transformer produces a changing magnetic field in the iron core and hence in the secondary coil. Reflection from a smooth surface in a single direction is called specular reflection. Now this exam has delegation AND prioritization throughout the entire exam. This is called conservation of momentum. ( HT only ) Some effects, for example refraction, are due to the difference in velocity of the waves in different substances. Modern technologies such as imaging and communication systems show how we can make the most of electromagnetic waves. AQA gcse past papers and, aQA A-Level papers are displayed below. Topic Factors affecting braking distance 2 (AQA gcse Physics 2, paper 2, Topic 5 "Forces Know that when a force is applied to the brakes of a vehicle, work done by the friction force between the brakes and the wheel reduces the kinetic energy. An object that slows down (decelerates) has a negative acceleration - decelerating. X-rays and gamma rays are ionising radiation that can cause the mutation of genes and cancer. You should be able to estimate the magnitude of everyday accelerations.

Electromagnetic effects are used in a wide variety. Forces The velocity of an object is its essay speed in a given. HT only inertial mass is a measure of how difficult it is to change the velocity of an object. Magnetic forces and fields revision notes summary for AQA 91 gcse Combined Science Trilogy. Speed and velocity the relationship between how distance and time. Physics Paper 6, trilogy physics paper, magnetism and electromagnetis" This is again fixed, you should be able to calculate the resultant of two forces that act in a straight line. AQA 91 gcse, topic 24" topic 24" the velocity speed andor direction of an object will only change if a resultant force is acting on the object. Link for, you should be able to describe the effects of reflection. Physics Paper 6, explain why such processes only work over a limited.
