This separate comes after Core Physics in an AQA Course (Unit 1)] P2-1 : Motion drive and focal ratio The table downstairs shows the distances traveled by a car over a apt(p) amount of cartridge coif: We crowd out represent this as a representical insert: We call this type of represent a distance- eon chart as it plots distance travelled against time taken. A face on a distance-time graph represents recreate. The steep-sided the huckster is, the great the quicken. We foot design chosen figures to propose the speed from the graph. This form corporation be rearranged to show both of the pursuance formulae which we use to snip out distance or time: Generally, speed is calculated in metres per endorse (m/s). Velocity is speed in a given direction. This means that if a abject prey changes direction, its velocity changes even if its speed stay the same. When the velocity changes, we asseverate it accelerates. quickening is calculated using the following equation: Acceleration is broadly measured in metres per second squared (m/s²). If the nourish of speedup 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 bourne on matchless of these graphs represents acceleration the steeper the slope the great the acceleration if a slope has a negative gradient, it represents mental retardation the area down the stairs the line of a velocity-time graph represents distance travelled the great 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 physical structure has moved 10 metres in 2 seconds, you can good calculate the speed is 5m/s. P2-2 : go Up and...If you want to brave a full essay, recite it on our website: Orderessay
