**Activity 1 - Horizontal and Vertical Speed**Question Groups 1- 6: Learners make comparisons and rankings of the horizontal and vertical speed of a projectile for several locations along the trajectory.**Activity 2 - Vector Diagrams**Question Groups 7-9: Learners identify the vector diagram for three locations along a projectile's trajectory when given the vector diagram for a fourth location on its trajectory.**Activity 3 - Time, Time, Time**Question Groups 10-13: Learners associate the values of the horizontal and vertical components of velocity as displayed in a vector diagram to a specific time in seconds.

Teachers are encouraged to either do the activity or view the questions (below) to make a judgement about the suitability of the activity for their classes. While we believe that the three Activities complement each other very well, each of the three can serve as stand-alone Activities that do not require the others as pre-requisites or follow-up Activities.

However, this document should not be uploaded to other servers for distribution to and/or display by others. The Physics Classroom website should remain the only website or server from which the document is distributed or displayed. We also provide a PDF that teachers can use under the same conditions.
