Identify the object’s initial velocity and final velocity (if using the average of velocities)
Compute average velocity using:
( v_{text{avg}} = dfrac{v_i + v_f}{2} ) (constant acceleration)
If using displacement and time, compute:
( v_{text{avg}} = dfrac{Delta x}{Delta t} = dfrac{x_f – x_i}{t_f – t_i} )
Use consistent units for distance (e.g., meters) and time (e.g., seconds)
If motion is over multiple intervals, compute total average velocity as:
( v_{text{avg}} = dfrac{sum Delta x}{sum Delta t} )
Ensure the sign of displacement (direction) is included in ( Delta x )
