TRANSCRIPT
A graph of the instantaneous velocity of an object over a specified period of time
Time is independent (x-axis)Velocity is dependent (y-axis)
Remember, velocity details magnitude (how fast) and direction (which way)

Units for the slope of time vs. velocity graph(m/s)/s → m/s2
Slope of t vs. v graph tells instantaneous acceleration
Straight lines on t vs. v graph = uniform (constant) acceleration

Instantaneous Velocity Velocity of an object at a specific moment
Average Velocity Avg velocity of an object over time
Instantaneous Acceleration How much object’s velocity is changing at
a specific moment Displacement
Change in position of an object over time
