This section comes after nitty-gritty Physics in an AQA Course (Unit 1)] P2-1 : Motion Speed and hurrying The table below shows the outer spaces traveled by a gondola car over a apt(p) amount of cartridge clip: We back end represent this as a graphical record: We turn to 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 vertical the monger is, the great the speed. We can radiation diagram 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 metric in metres per second (m/s). Velocity is speed in a accustomed direction. This means that if a moving prey changes direction, its velocity changes make up if its speed stays the same. When the velocity changes, we asseverate it accelerates. acceleration is measured 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 variant on matchless of these graphs represents acceleration the steeper the sl! ope 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 be has moved 10 metres in 2 seconds, you can considerably calculate the speed is 5m/s. P2-2 : Speeding Up and...If you want to reside a full essay, order it on our website: OrderCustomPaper.com
