Constant Acceleration Flashcards
1
Q
Deriving v = u + at
A
Gradient of velocity-time graph (a) = (v-u)/t
v = u + at
2
Q
Deriving s = 1/2(v+u)t
A
Area under a velocity-time graph (trapezium)
3
Q
Deriving v^2 = u^2 + 2as
A
Rearrange for t = (v-u)/a
Substitute into s = 1/2(v+u)t
4
Q
Deriving s = ut + 1/2at^2
A
Substitute v = u + at into s = 1/2(v+u)t
5
Q
Deriving s = vt - 1/2at^2
A
Substitute u = v - at into s = 1/2(v+u)t
6
Q
