ETM Video Lecture

For CP and Honors classes working through the ETM unit right now, I've created four lecture videos to help you learn the  skills assessed in the four ETM standards. Find the links below.

ETM.1 Drawing a LOL diagram
ETM.2 Writing an expression from the LOL diagram
ETM.3 Solving for an unknown with the expression
ETM.4 Using trig to solve for an unknown length of a triangle

Momentum Standards 3, 4, 5

Here are the links to videos to help you learn the content for standards 3, 4, and 5 in momentum.

Momentum 3: Find the velocity of an object in a collision or explosion
Momentum 4: Model a collision or explosion with an IF chart
Momentum 5: Find the acceleration of an object and the force required to accelerate it

Retakes are available until April 14th.

The goals of the pulley lab

The goals of the pulley lab
1) Find the angular acceleration (experimental value) using a linear regression of your d-t^2 data.
2) Find the linear acceleration of the string using the angular acceleration found in 1.
3) Find the theoretical linear acceleration using Newton's Second Law (Fnet = ma) of the two masses.
