Unit 2 Newton's 2nd Law
Anti-green: Must-Do, green: Should-DO, anti-red: Strive-to-Do, and anti-blue: extra help.
All activities should be completed cooperatively with 1 partner, unless otherwise noted.
Before asking Mr. Skapetis a question, you must ask 3 classmates your question. If they do not sufficiently answer your question, then you may ask. It's not that he doesn't want to help you, but this policy frees him to reteach and grade the steady flow of work.
If there seems to be a glitch in my system or thinking, please let me know so this can be a smooth process going forward.

Lesson 2.1 Acceleration
I can identify the constant acceleration due to gravity neglecting air resistance
I can experimentally determine the acceleration due to gravity
I can identify positive and negative acceleration
4) Extra Linearization Practice
Review the video and complete the questions below.
4) Practice Problems
Answer as many of these problems as you need. Do not check the solution until you have justified every answer.
Lesson 2.2 Representing Accelerated Motion
I can calculate constant acceleration from a velocity vs time graph
I can translate between x vs t, v vs t, and a vs t graphs

3) Practice Problems
Answer as many of these problems as you need. Do not check the solutions until you have justified every answer.
5) Calculus Connection
Focus on the 2nd derivative. This just means you differentiate the function once, then differentiate it again. x(t)'' = a!
Lesson 2.3 Constant Acceleration Equations
I can use the kinematic equations to solve for an unknown variable
I can describe when the kinematic equations are no longer valid
2) Practice Problems

Lesson 2.5 Forces in Vertical Motion
I can calculate force given mass and acceleration and calculate acceleration given force and mass
I can combine Newton’s second law with the kinematic equations to solve force/motion problems
I can describe the difference between mass and weight
I can define net force and net acceleration
I can create Newton's 2nd Law equations from a well designed free-body/force diagram
