Variable Acceleration (2D) Flashcards
1
Q
If you are given acceleration, how do you get to velocity?
A
integrate
v=∫adt
2
Q
If you have velocity, how do you get to displacement? (s or r)
A
integrate
s/r = ∫vdt
3
Q
If you have displacement (s or r), how do you get to velocity?
A
differentiate
v=ds/dt
4
Q
If we have velocity, how do you get to acceleration ?
A
differentiate
a=dv/dt
5
Q
If you have displacement, how can you get to acceleration?
A
differentiate twice
a=d^2s / dt^2
