9/26

Objective:  SWBAT draw and interpret  free body diagrams.

Warm Up: Draw a free body diagram of a ball rolling down a hill.

Yesterday and today are lab days.  Yesterday we did the Constant Force and Constant Mass labs on Newton's 2nd Law.  Today you will be broken into one of two groups that will design and carry out a formal lab on the relationship between force and acceleration OR mass and acceleration.  You will be using fellow classmates on roller skates to perform the experment.

9/24

Objective: SWBAT explore the effects of changing force on an object and mass of an object on that object's acceleration.

Warm Up: Choose a group of NO MORE THAN 3 students to work with. Make sure you are working with someone you haven't worked with so far this year (failure to follow these directions will result in a 10 point deduction in your lab's grades.  Pick up one white lab handout and one yellow handout PER GROUP.  As a group, preread the instructions on both lab handouts.

9/21

Objective:  SWBAT calculate the weight of an object and distinguish this from the object's mass.

Warm Up:  What is your mass?  What is your weight on Earth?  What is your mass on the moon?  What is your weight on the moon?  Use correct SI units, please!

9/20

Objective:  SWBAT understand the concept of inertia and how it relates to motion.

Warm Up:  Get into a group of 2 or 3.  Pick up the lab handouts.  Answer the pre-lab questions.

9/18

Objective:  SWBAT review for tomorrow's test on 2 D kinematics

Warm Up:  Determine what is happening to the objects motion based on the signs

9/17

Objective:  SWBAT solve problems involving 2 D kinematics.

Warm Up:  What variables do you know at ymax that are usually not stated in the problem?
