Answer:
Slope
Step-by-step explanation:
On a speed- time graph, the slope measures acceleration of the object. The mathematical form of acceleration is given by :
a = (charge in velocity)/(change in time)
For example :
In the attached graph, the y axis shows speed and the x axis shows time taken. The slope of the graph can be calculated as :
\(m=\dfrac{y_2-y_1}{x_2-x_1}\)
\(m=\dfrac{20-0}{2-0}\)
Acceleration, a = m = 10 m/s²
So, on v-t graph, the slope measures the acceleration.
