Calculating the speed from a distance-time graph To find the speed of an object from a distance-time graph, we need to calculate the gradient (or slope) of the line
Answers
Answer:
Explanation:
Background informationThe vertical axis of a distance-time graph is the distance travelled from the start. The horizontal axis is the time from the start.
Features of the graphsWhen an object is stationary, the line on the graph is horizontal. When an object is moving at a steady speed in a straight line, the line on the graph is straight but sloped.
Note that the steeper the line, the greater the speed of the object. The blue line is steeper than the red line because the blue line represents an object which is moving more quickly.
Calculating speed - Higher tierWhen an
object moves in a straight line at a steady
speed, you can calculate its speed if
you know how far it travels and how long it takes. This equation shows the relationship between speed, distance travelled and time taken:
speed = distance travelled
time taken
Speed is measured in metres per second, m/sDistance is measured in metres, mTime taken is measured in seconds, sFor example, a car travels 300 m in 20 s. Its average speed is:300 ÷ 20 = 15 m/s plz mark as brainliest
