Kinematics in One Direction Cheat Sheet

Displacement and Distance
Displacement- vector extending from object's
initial position to its final position
Distance- scalar quantity representing the
actual path followed by an object
Distance equals displa
cement when the object
travels in a straight line and does not reverse its
direction
Velocity and Speed
Velocity- vector describing the rate of
displacement
average velocity = displa
cem
ent
/time
Instantaneous velocity- velocity at a spe cific
time
Speed- scalar calculating the rate of d istance
average speed = distan
ce/
time
If an object travels in a straight line, then speed
and velocity are interc
han
geable
Acceleration
Acceleration- rate of change of velocity
accel
eration = change in veloci
ty/
time
Uniform acceleration- magnitude remains
constant; constant acceleration- magnitude
and direction are constant
If acceleration acts in the same direction as
velocity: speed increases
If acceleration acts in the opposite direction as
velocity: speed decreases
If acceleration acts perpendicularly to velocity:
direction changes
The accele
ration of gravity is 10 m/s
Kinematic Equations
vf = vi + 2ax
vf = vi + at
x = vi*t + 0.5at
v=x/t or x=vt
