Physical Science A
Today we will go over the test.
Discuss the test results. If you have a question, now is the time to ask!
You will each get a test remediation. The remediation is designed to have you answer questions only based on the questions that you miss on the test. You will receive a report showing what questions you missed. Use this to determine what questions on the remediation you must answer. Also, three hole punch this sheet and keep it in your binder!
The remediation should be finished by the end of the day.
The Vocabulary will be check tomorrow.
I will walk around and check your binders today.
If you finish early, get started reading Chapter 2, sections 2 and 3, along with all of chapter 3. Take notes on the material.

Once finished, you will then use the photogates to make quantitative observations of two collisions. When finished you will determine if momentum was truly conserved based on your observations and data.
We have only four tracks that can be used to collect data, so we will have to share. Take turns using the tracks. Set the carts on the track, produce the collision, and make your observations, collect the data, and let the next group go. As a group records their observation, another can set-up and produce their collisions.

Friction Lab:
This lab will allow you to calculate the coefficients of static and kinetic friction. This lab requires extreme care if you are to calculate the results correctly.
The setup is designed to allow you to slowly increase the angle of the board. By doing this you will also increase the force pulling the block down the incline. The correlation is
increased angle = increased down force
As the angle and force then increase, there will be an angle where the block begins to move due to the increase size of the down force. It is at this exact angle where the down force is equal to the force of static friction.
Secondly, you will set the board at an angle larger than the motion angle in part a. You will then calculate the acceleration of the block as it moves down the incline. The acceleration can then be used to calculate the coefficient of kinetic friction.

2. Draw vector diagrams (arrows with magnitudes) that Identifies the magnitude and direction of everyday forces (e.g., wind, tension in ropes, pushes and pulls, weight).
3. Describe the different types of friction and how they affect the motion of an object.
Discuss, check, and go over the friction lab.
Check and go over the 2nd law of motion problems. Use the whiteboards to check.
Discuss the 2nd Law of motion and the force of gravity.
Scavenger Hunt: Each group will have a list of clues. You will have to guess what the object is and use the scale in the room to measure the mass of the object. Once you have the mass, you will use this information to calculate force of gravitational attraction between you and the object.
HW: Finish the calculations from the scavenger hunt.

Physical Science A
Bellwork:
1. What is friction and how does it affect the motion on an object?
2. Explain an give examples of Newton's 1st and 2nd Laws.
Objectives:
1. List and describe the typical force that you experience and interact with on a daily basis.
2. Draw vector diagrams (arrows with magnitudes) that Identifies the magnitude and direction of everyday forces (e.g., wind, tension in ropes, pushes and pulls, weight).
3. Describe the different types of friction and how they affect the motion of an object.
Check and go over the homework(newton's second law of motion). Use the whiteboards.
Continue discussing Newton's Second Law
Lab: Friction
HW: Finish the 2nd Law of Motion problems. Finish the lab questions.
Physics
-Hand in the projectile motion lab.
Today is balloon launch day. You will use your knowledge of projectiles, velocity, and angles to find the range of the launchers.
Formulas to keep in mind:
Vf=Vi+gt
Vf2=Vi2+2gd
d=Vit+(.5)gt2
**Need to keep the velocity the same!**
**Maximum Range is at angle of 45o**
Each group will receive two balloons, one to determine the range, one for testing. At 12:35 we will take the class, the balloons, and the launcher out to the practice field and test.
Closest to the target wins!!!!
HW: Projectile motion problems.
We will have a short test on Wed. next week.

Physical Science A
Quick Quiz. Let's see who is studying.
Bellwork:
1. What is the acceleration of an object that accelerates from rest to a velocity of 88 m/s in a time of 11 seconds. If the acceleration of the object were constant, what would the graph of this motion look like?
2. If an object falls from a resting position and reaches a speed of 23 m/s just before it strikes the
ground, what is the time required for the object to strike the ground(remember that acceleration due to
gravity here on Earth is 9.8 m/s2)?
3. Describe the shape of a velocity vs. time graph that:
-shows an object traveling at a constant velocity
-shows an object traveling with an increasing velocity.
Objectives:
1. List and describe the typical force that you experience and interact with on a daily basis.
2. Draw vector diagrams (arrows with magnitudes) that Identifies the magnitude and direction of
everyday forces (e.g., wind, tension in ropes, pushes and pulls, weight).
Go over the homework.
Discuss Newton's First and Second Law's of Motion
Demo, loop and washer, tablecloth, block and string. Discuss
Hand out and explain 2nd law problems.
HW: finish Newton's Second Law Problems
Physics
Today we will switch groups. If you collected data yesterday, you should work on the projectile motion problems today and vice versa.
At 12:45, we will stop. Everyone should have there calculations set. I will set out the ramp for the launchers. Each group will have the opportunity to fire one shot and see if they are on target with their calculations. The team closest to the target wins.
At the end of the hour each group should pick up the "Right on Target" paper. You will work in groups and as a class to determine the range of the water balloon shot from the sling shot. The group closest to the target wins.
The sling shot competition will take place on Friday(hopefully).
HW: Everyone should finish their summary question from the lab. Also, discuss with your groups how to determine the initial velocity of the launcher.
