Acceleration 11-3
Acceleration =
A change in speed
(Velocity) or direction
in an amount of time
Speed 2 - Speed1 / t
V2 – V1 / t
Acceleration
Units = m / s2
Units =
meters / second /second
Slow down—is accelerating
Acceleration is speeding
up
Slowing down is called
Deceleration or Negative
Acceleration
Constant Acceleration =
A steady change in velocity
The velocity changes by the
same amount each second
Positive Acceleration Graph
Increase at a
constant rate =
straight line
Slope of line =
acceleration
Negative Acceleration Graph
Decrease at a
constant rate =
straight line
sloping
downward
Slope is
negative
