Physics

No Bellwork Today!

Discuss Projectile Motion.  Why our formulas won't work for calculations and what we need to do to adjust.

Activity:
    Determine the Height of Objects

HW:  Finish Calculations and pick-up packet on vectors and projectiles.  Do vector problems.


Physical Science A

Bellwork:
    -Why is it that when a car travels around a curve, you feel a pull to the outside?

    -What are some examples of situations where you have felt similar types of interaction acting on your     body?

Today:
    -I will collect the test remediation and check the vocabulary.  Please have these out.

Objectives:
    -Be able to calculate the acceleration of an object given the changes in velocity and change in time. 
    -Identify type of motion an object is experiencing given a velocity vs. time graph.

Discuss acceleration, what causes acceleration, and how to calculate the acceleration of an object.

Math Problems:
    Discuss and go over example of how to calculate the acceleration of an object.

HW: Finish the acceleration problems on the math packet. 

-We will go over these tomorrow in class.
