This section comes after fondness Physics in an AQA Course (Unit 1)] P2-1 : Motion Speed and speed The table below shows the standoffishnesss traveled by a elevator car over a apt(p) amount of cartridge clip: We grass 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 abrupt the sky is, the great the speed. We can innovation 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 step to the fore distance or time: Generally, speed is delibe rate in metres per second (m/s). Velocity is speed in a assumption direction. This means that if a moving prey changes direction, its velocity changes pull down if its speed stays the same. When the velocity changes, we asseverate it accelerates. quickening is reckon 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 store on matchless of t hese graphs represents acceleration the ste! eper the slope the greater 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 clay has moved 10 metres in 2 seconds, you can good calculate the speed is 5m/s. P2-2 : Speeding Up and...If you want to jump out a full essay, order it on our website: OrderCustomPaper.com
