Y1, C9 - Constant Acceleration Flashcards
What is the average velocity if you end a journey where you started
0
What does the area under a velocity time graph give
The distance travelled
What is acceleration
The rate of change of velocity
What is velocity
The rate of change of displacement
What does a have to be to use SUVAT equations
Constant
What is the area under a velocity time graph equal to
The distance travelled
What is the gradient of a velocity time graph equal to
The acceleration
What is the formula for the area of a trapezium
0.5(a + b) * h
Using a velocity against time graph with u and v on the y axis, what equations do the gradient tell us
a = (v-u)t
v = u + at
Using a velocity against time graph with u and v on the y axis, what equation does the area tell us
s = ((u+v)/2) * t
How do you derive the two formulas that you can’t get from a velocity time graph
Rearranging and substituting into the equations you can derive from them
