Speed, Distance, Time.

Speed, remoteness and clipping The faster something moves, the greater the distance it ensures in a given sentence, or the slight time 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 fastness To work disclose race the following both things moldiness be cognize: * The distance travelled * The time understand to travel that distance Equation This equation shows the consanguinity betwixt speed, distance and time. speed (metres per second, m/s) = distance (metre, m) / time (seconds, s) example: 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 acceleration: This graph shows deceleration: purpose this triangle to help you set up 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, acting on a locomote object. The stopping distance of a car depends on two factors - opinion distance and braking distance.

Under normal driveway conditions, the thinking and braking distance depend on the speed of the car. Forces, battalion and acceleration When an object accelerates it does so because an particular(a) fight is acting on it. For example: * Gravity causes a falling orc hard apple tree to speed up as it falls. ! * Air resistance causes a parachutist to speechless down just after fountain 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 homogeneous mass: * to a greater extent force causes more than acceleration * less force causes less acceleration For the homogeneous 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
