Speed, Distance, Time.

Speed, remoteness and clipping The faster something moves, the greater the distance it pass throughs in a given sentence, or the less(prenominal) while it takes to cover a given distance. For modeling, a car that is driven 100km in 2 hours is going faster than one covering 60km in 2 hours, and the fastest 100m sprinter finishes in the least time. Calculating stronghold To work disclose fastness the following both things moldiness be cognize: * The distance travelled * The time understand to travel that distance Equation This equation shows the consanguinity surrounded by speed, distance and time. speed (metres per second, m/s) = distance (metre, m) / time (seconds, s) physical exercise: A person runs 200m in 20s speed = distance/time speed = 200m/20s speed = 10m/s distance = speed x time time = distance / speed This graph shows quickening: This graph shows deceleration: purpose this triangle to help you rearrange the equation to: change in speed = acceleration x time taken time taken = change in speed / acceleration Speed-time graphs A speed-time graph tells us how the speed of an object glass changes over time. Acceleration is caused by a draw out, eg gravity or friction, playacting on a locomote object. The stopping distance of a car depends on two factors - opinion distance and braking distance.

Under normal campaign conditions, the thinking and braking distance depend on the speed of the car. Forces, band and acceleration When an object accelerates it does so because an special fight is acting on it. For example: * Gravity causes a falling apple to speed ! up as it falls. * Air resistance causes a parachutist to speechless down just after enterprise the parachute. * The brake pads on a bike cause extra friction, which slows the bike down. The kinship between force, mass and acceleration For the alike mass: * to a greater extent force causes more than acceleration * less force causes less acceleration For the similar force: * more mass causes less acceleration * less mass causes more acceleration For...If you want to get a full essay, order it on our website: OrderCustomPaper.com
