Here we see an animation that shows the relation between these two quantities:

• The slope of the x vs. t graph.
• The value of the velocity.

This page is very similar to the XVA - Constant Velocity Animate 1 page. However, on that page the object's starting position was at the origin, or x_o = 0.0 m. On this page the object's starting position is at a positive coordinate, x_o = 40.0 m.

The object always starts at the same position, 40.0 m. It moves away from that starting position with a constant velocity. The object's velocity is always constant. It changes in value from +6.0 m/s to -6.0 m/s. The constant acceleration is always 0.0 m/s2. So, none of the velocities change.

This Java applet demonstration is set up for xo = 40.0 m and vo = 6.0 m/s. You can change this starting velocity to other values, (keeping the acceleration at 0.0 m/s2), to see situations similar to those shown in this animation. [1] Java applet demonstration

Comments:

• These comments are the same a those on the XVA - Constant Velocity Animate 1 page. Moving the starting position of the motion away from the origin to a positive coordinate does not change the relationship between the slope of the x vs. t graph and the value of the velocity.
• The slope of the object's x vs. t graph is the velocity of the object.
• When the velocity is large and positive, the slope of the x vs. t graph is large and positive.
• When the velocity is small and positive, the slope of the x vs. t graph is small and positive.
• When the velocity is zero, the slope of the x vs. t graph is zero.
• When the velocity is small and negative, the slope of the x vs. t graph is small and negative.
• When the velocity is large and negative, the slope of the x vs. t graph is large and negative.
