In this lab, you will use a dynamics track to generate collisions between two carts. If momentum is conserved, what variable change would result in a velocity change after a collision? In the space below, write a scientific question that you will answer by doing this experiment. E2020

Alinear relationship would look like a straight line on the graph. it could have a positive negative or 0 slope. so it could be a line potentially going in any direction but it must be perfectly straight.

How is it possible that phylogenies based on sequences from nuclear genomes and organellar genomes (i.e., chloroplasts and mitochondria) from the same group of species yield phylogenetic trees with different branching orders?   answer :   the genome of the endosymbiont is more closely related to members of the group in which it originally evolved, while the nuclear genome of the engulfing organism has its own evolutionary trajectory.

Newton's first law describes something special that results from the sum of all the external forces (including gravity) on an object.
