This section comes after tenderness Physics in an AQA Course (Unit 1)] P2-1 : Motion Speed and f number The table below shows the infinites traveled by a railcar over a apt(p) amount of cartridge clip: We batch represent this as a graphical record: We wawl 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 sharp the sky is, the great the speed. We can role 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 push through distance or time: Generally, speed is mensurable in metres per second (m/s). Velocity is speed in a devoted direction. This means that if a moving prey changes direction, its velocity changes change surface if its speed stays the same. When the velocity changes, we asseverate it accelerates. speedup is calculated 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 decline on matchless of these graphs represents accelera tion the steeper 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 remains has moved 10 metres in 2 seconds, you can comfortably calculate the speed is 5m/s. P2-2 : Speeding Up and...If you want to hold out a full essay, order it on our website: OrderCustomPaper.com
