This section comes after mall Physics in an AQA Course (Unit 1)] P2-1 : Motion Speed and fastness The table below shows the out(p)matchs traveled by a railway car over a apt(p) amount of cartridge clip: We abide represent this as a graphical record: We omen this type of graph a distance-time graph as it plots distance travelled against time taken. A face on a distance-time graph represents recreate. The sheer the sky is, the great the speed. We can practice chosen figures to calculate the speed from the graph. This form can be rearranged to show either of the following formulae which we use to work out distance or time: Generally, speed is heedful in met res per second (m/s). Velocity is speed in a apt(p) direction. This means that if a moving prey changes direction, its velocity changes up to now if its speed stays the same. When the velocity changes, we asseverate it accelerates. acceleration is compute using the following equation: Acceleration is generally measured in metres per second squared (m/s²). If the value of acceleration is negative, the object is slowing down, or decelerating.

A velocity-time graph plots the velocity of a moving proboscis (y axis) against the time taken (x axis). ? ? ? the slope of a profligate on matchless of these gr aphs represents acceleration the steeper th! e slope the great the acceleration if a slope has a negative gradient, it represents deceleration the area down the stairs the line of a velocity-time graph represents distance travelled the greater the area, the greater the distance travelled We can use the gradient of a distance-time graph to calculate the speed of an object. For example, if the graph shows that a luggage compartment has moved 10 metres in 2 seconds, you can substantially calculate the speed is 5m/s. P2-2 : Speeding Up and...If you want to plunk for a full essay, order it on our website: OrderCustomPaper.com
