A
Rate of change of displacement
3
Q
Definition of acceleration
A
Rate of change of velocity
4
Q
Formula for average acceleration
A
(v-u)/t
5
Q
What does the gradient of a DT graph represent?
A
Velocity
6
Q
What does the gradient of a VT graph represent?
A
Acceleration
7
Q
What does the area under a VT graph represent?
A
Displacement
It can be positive or negative depending on net displacement
8
Q
Equations of motion
A
v = u + at v^2 = u^2 + 2as s = ut + 1/2at^2 s = 1/2(u+v)t
9
Q
Formula for average velocity
A
1/2 (u+v)
