![]() This means the horizontal acceleration is zero which matches up the horizontal position vs. This is like our previous model of constant velocity motion. The slope of the line represents the horizontal speed, which remains constant during flight. At the end of the board meeting, the class has created a model for projectile motion: Video analysis in Logger Pro (image credit: )Īfter the data collection and analysis, students “whiteboard” their graphs and we have a “board meeting” where each group presents their results and then as a class we try to make connections among the groups and come to a consensus. Everyone makes a contribution to our classroom scientific community. This is whole class inquiry - groups are doing different experiments and everyone’s data is needed. time graphs created and look for patterns in their shapes and in their equations. One group will vary ball mass, another toss speed, and another arc shape. So, as a class, we decide to split up the data collection.
