Motion 0.0 / 5 ScienceMotionGCSEAQA Created by: Holly45Created on: 09-03-15 17:08 Motion speed is measured in m/s speed = distance divided by time 1 of 5 Distance time graphs Y- axis is the distance travelled X- axis is the time the steeper the line, the greater the speed when an object is stationary, the line is horizontal distance in one direction is positive, and negative is in the other direction 2 of 5 Velocity time graphs the velocity of an object is its speed in a particular direction when an object is moving with a constant velocity, the line is horizontal the steeper the line, the more rapidly the velocity is changing the line sloping down represents an object that's steadily slowing down 3 of 5 Acceleration acceleration = change in velocity divided by the time taken V-U = AxT V is the final velocity U is the initial velocity measured in m/s squared acceleration is how quickly the velocity is changing 4 of 5 Gradient divide the change in the vertical axis by the change in the horizontal axis on a distance time graph is represents the speed of an object 5 of 5
