| In this activity, you will be asked to complete several tasks involving what you have learned about describing motion and applying this knowledge to actual computer program code. In describing motion at this point, we need to consider both position and velocity. To keep this activity simpler, you will be working with constant velocity, either positive or negative. | In this activity, you will be asked to complete several tasks involving what you have learned about describing motion and applying this knowledge to actual computer program code.
