DESCRBING MOTION : KINEMATICS IN 1D
2-1
REFERENCE FRAMES & DISPLACEMENT
DISPLACEMENT
:
how far
the obejct is from starting point, regardless of how it got there.
Δx=
x2-x1
DISTANCE :
Traveled is measured
along
the actual path.
2-7 FREE FALLING OBJECTS
x =
xo + ut - 1/2 (gt^2)
v^2 =
u^2 - 2gs
v =
u - at
2-5
MOTION AT
CONSTANT ACCELERATION
x =
xo + ut + 1/2 (at^2)
v^2 =
u^2 + 2as
v =
u + at
v ˉ =
( u + v ) / 2
2-3 INSTANTANEOUS VELOCITY
v =
dx / dt
2-2 AVERAGE VELOCITY
AVERAGE SPEED, V
= [distance travelled (
x
)] / [time elapsed (
t
)]
AVERAGE VELOCITY , v ˉ =
Δx / Δ t
2-9 GRAPHICAL ANALYSIS & NUMERICAL INTEGRATION
The
total displacement
of an object can be described as the
area under the v-t
curve :
2-8 VARIABLE ACCELERATION; INTEGRAL CALCULUS
so, for the
constant acceleration =
Then,
so, for the
constant acceleration =
