3. Velocity vs Time Graphs
ACCELERATION: a vector quantity that refers to the rate at which an object changes its velocity.
Speeding up or slowing down.
Units = meters per second squared (m/s2)

4. Velocity vs Time Graphs
Another way to describe motion is a velocity vs time graph.
X-axis: time (s)
Y-axis: velocity (m/s)
The slope of the line is the object’s acceleration.

5. Velocity vs Time Graphs
Flat/horizontal line =
Straight line =
Curved line =
Constant velocity. NO ACCELERATION.
CONSTANT ACCELERATION. Speeding up or slowing down at a constant rate
Changing / Varied Acceleration
