Motion equations Flashcards
1
Q
average speed =
A
total distance/total time
2
Q
average velocity=
A
change in displacement/ change in time
3
Q
average velocity 2 =
A
v(final) + v(initial)/2
4
Q
instantaneous velocity =
A
dx/dt
5
Q
average acceleration =
A
change in velocity/ change in time
6
Q
instantaneous acceleration =
A
dx2/dt2
7
Q
v(final) =
A
v(initial) + at
8
Q
change in displacement (x) =
A
v(initial)t + 1/2at^2
9
Q
v(final)^2 =
A
v(initial)^2 + 2ax
10
Q
v(final)(free fall) =
A
v(initial) - gt
11
Q
change in displacement(y)(free fall) =
A
v(initial)t - 1/2gt^2
12
Q
v(final)^2 (free fall) =
A
v(initial)^2 - 2gy
