Velocity vs. Time graphs

What is the shape of a velocity graph for constant velocity?

• diagonal line

• flat line

• parabola

Which side of the graph shows an object coming towards the origin.

• positive

• negative

• zero line

What does  $\Delta x$  mean?

• change in position

• sum of position

• duration

• position

Change in position ( $\Delta x$  ) means:

• direction

• distance

• displacement

How do you find  $\Delta x$  (displacement) on a position graph?

• slope

• y-intercept

• Xf - Xi

• area
