# Motion Terminology Self Test Play the Motion Terminology Self-Test! You must get 10 answers correct in a row. If you get one wrong, you will have to restart the whole thing.

Ok, now try this one: Finding Velocity from Position Graph

# ROTATION LAB!!! # CSI Projectiles Click here to go to the lab activity for today. Type your answers into that document and share it with me when you finished it.

When you are done with the CSI activity, complete the two short tasks below. Pay attention to the units and make sure you read the question so you know what you are supposed to answer. Screenshot your success and share it with me.

# Throwback Thursday (on a Wednesday) Try this old example of finding the net force of three forces at different angles.

Almost like a Quadrant-tester for cell F7:

=IF(AND(D7>0,E7>0),1,IF(AND(D7<0,E7>0),2,IF(AND(D7<0,E7<0),3,IF(E7=0,0,4))))

Updated formula for the resultant angle in cell C7:

=IF(F7=0,0,IF(OR(F7 = 2, F7 = 3), 180 + DEGREES(ATAN(E7/D7)), IF(F7=4, 360 + DEGREES(ATAN(E7/D7)), DEGREES(ATAN(E7/D7)))))
