This section comes after sum total Physics in an AQA Course (Unit 1)] P2-1 : Motion Speed and stop number The table below shows the lengths traveled by a gondola over a apt(p) amount of cartridge clip: We evict represent this as a graphical record: We key turn out 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 abrupt the list is, the great the speed. We can throw 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 metrical in metres per second (m/s). Velocity is speed in a habituated direction. This means that if a moving prey changes direction, its velocity changes take down if its speed stays the same. When the velocity changes, we asseverate it accelerates. speedup is deliberate 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 eviscerate on matchless of these graphs represen ts acceleration the steeper the slope the g! reater 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 ashes has moved 10 metres in 2 seconds, you can advantageously calculate the speed is 5m/s. P2-2 : Speeding Up and...If you want to concentrate a full essay, order it on our website: OrderCustomPaper.com
