The compass needle points in the direction of the earths magnetic field. The speed of sound and the speed of the wind also vary. The greater the braking force the greater the deceleration of the vehicle. If an object is accelerating, its speed at any particular time can be determined by drawing a tangent and measuring the gradient of the distancetime graph at that time. The distance travelled by an object (or displacement of an object) can be calculated from the area under a velocitytime graph.
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. The strength of the magnetic field depends on the current through the wire and the distance from the wire Buy now Ocr Higher Terminal Past Papers
Large decelerations may lead to brakes overheating and loss of control. The force between a magnet and a magnetic material is always one of attraction. When removed from the magnetic field an induced magnet loses mostall of its magnetism quickly. An object falling through a fluid initially accelerates due to the force of gravity. Grade 12 september 2012 business studies - primex.
Know that the region around a magnet where a force acts on another magnet or on a magnetic material (iron, steel, cobalt and nickel) is called the magnetic field. . 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 data Ocr Higher Terminal Past Papers Buy now
Know if an object moves along a straight line, how far it is from a certain point can be represented by a distancetime graph. Exam revision summaries and references to science course specifications are unofficial. The force between a magnet and a magnetic material is always one of attraction. You should be able to use vector diagrams to illustrate resolution of forces, equilibrium situations and determine the resultant of two forces, to include both magnitude and direction (scale drawings only). Electromagnetic waves form a continuous spectrum and all types of electromagnetic wave travel at the same velocity through a vacuum (space) or air.
You should be able to show that flemings left-hand rule represents the relative orientation of the force, the current in the conductor and the magnetic field Buy Ocr Higher Terminal Past Papers at a discount
The weight of an object can be calculated using the equation weight mass ч gravitational field strength (note that in any calculation the value of the gravitational field strength (g) will be given. The speed of sound and the speed of the wind also vary. Some models do have a ntc type temperature sensor that allows the map to detect, not only the. Know that the braking distance of a vehicle can be affected by adverse road and weather conditions and poor condition of the vehicle. Free download here ministry of education - nied httpwww.
Know that when a force causes an object to move through a distance work is done on the object. English as a second language - papers - xtremepapers. You should be able to give examples that illustrate the transfer of energy by electromagnetic waves Buy Online Ocr Higher Terminal Past Papers
An induced magnet is a material that becomes a magnet when it is placed in a magnetic field. The frequency of a wave is the number of waves passing a point each second. The greater the braking force the greater the deceleration of the vehicle. Ultraviolet waves can cause skin to age prematurely and increase the risk of skin cancer. So, the velocity (speed andor direction) of an object will only change if a resultant force is acting on the object.
Know that when a current flows through a conducting wire a magnetic field is produced around the wire. An electromagnet is a solenoid with an iron core. The weight of an object depends on the gravitational field strength at the point where the object is Buy Ocr Higher Terminal Past Papers Online at a discount
Near the earths surface any object falling freely under gravity has an acceleration of about 9. You should be able to apply this equation which is given on the physics equation sheet. You should be able to make measurements of distance and time and then calculate speed. Know that reaction times vary from person to person. Ultraviolet waves can cause skin to age prematurely and increase the risk of skin cancer.
Electromagnetic radiation, types, properties, uses and the spectrum of visible light ) know that different substances may absorb, transmit, refract or reflect electromagnetic waves in ways that vary with wavelength. You should be able to explain how the force on a conductor in a magnetic field causes the rotation of the coil in an electric motor Ocr Higher Terminal Past Papers For Sale
Adding an iron core increases the strength of the magnetic field of a solenoid. For example ) you should be able to give brief explanations why each type of electromagnetic wave is suitable for the practical application. Tue, 183600 gmt past papers o l pdf - g. The compass needle points in the direction of the earths magnetic field. Acceleration, velocity-time graph interpretation and calculations, problem solving know newtons first law if the resultant force acting on an object is zero and the object is moving, the object continues to move at the same speed and in the same direction.
The magnetic field around a solenoid has a similar shape to that of a bar magnet. The acceleration of an object can be calculated from the gradient of a velocitytime graph For Sale Ocr Higher Terminal Past Papers
You should be able to express a displacement in terms of both the magnitude and direction. The direction of the magnetic field at any point is given by the direction of the force that would act on another north pole placed at that point. The length of the arrow represents the magnitude, and the direction of the arrow the direction of the vector quantity.
