We’ll be doing some video analysis in Capstone today.

# 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)))))

Try these circuit challenges to test your circuit skills.

# Simple Harmonic Motion

IT”S FRIDAY!!!!!

Working with a buddy, try these two problems:

- Kinetic Energy to Oscillation
- Masses and Springs –
**TURN FRICTION OFF**when running this- What is the mass of the Red Mass?
- What is the mass of the Green Mass?
- What is the gravitational field strength on Planet X?
