Projectile Motion Practice Problems

HW for the weekend (Galileos and Einsteins) or Monday night (Newtons):  Horizontal Projectile Motion Problems.  This is your first assignment of Q2!  Don't forget, test coming up on Friday the 7th.

Projectile (aka 2-dimensional) motion

HW is reading in The Physics Classroom.  Read over the following four sections.  The third and fourth section review what we did in class today.  Due Friday for Galileos/Einsteins, Monday for Newtons.

Go to The Physics Classroom, Tutorial, Vectors-Motion and Forces in Two Dimensions, and read lessons 2a-2d.  Again, this should look familiar based on what we did in class.

This is just a screen shot- it isn't a link.

Free Fall, Up and Down Problems

HW tonight (Tuesday for Galileos/Einsteins, Wednesday for Newtons) is called "Fay Wray problems."  There's actually only one about Fay Wray, but its a more imaginative title than "More Free Fall problems."  Here's a photo reference:

There she is- teeny tiny in King Kong's hand.  Anyway, free fall.

These problems are CHALLENGING.  That doesn't mean you can't do them- you can.  Make a list.  For several of the problems you need to use one equation to find the time, then plug the time into a second equation.  Do stay neat and organized as you solve the problems.

Monday Night

No new HW tonight...instead I would like you to go through Aspen and check to see if you are missing anything (NTI = Not Turned In = 0).  Turn any missing work into your folder.  Remember, the quarter closes Friday- no late HW accepted after then!

Your dog can't eat your iPad homework...so guess that means you have no excuses, right?  RIGHT?!?!?

Graphing Quiz, Take 2

If you got less than 80% (less than 18.5/23) on the quiz you can do a retake up to 80%.  This will be in class on Monday.  To review:

1.  Look over the chart of notes we did in Notability called "More graphing hints."  Look at your quiz with these notes to make corrections.

2.  Open a clean copy of "Graph Sketching HW" into Notability and complete it again.  Check your work using the KEY.

3.  Open a clean copy of "Describe the Graph" into Notability and complete it (this was not originally assigned but there as a resource).  Check your work using the KEY.

Free Fall: How far has it fallen?

Galileos and Einsteins: Monday night HW is "Free Fall Displacement and Velocity Problems."  Newtons you will do this Tuesday night.  Due Wed for everyone.

Free fall practice problems

HW over the weekend for all sections:  "Velocity and g problems" found in the folder.

Have a good weekend!

HW after the quiz

Reading and notes in the Physics Classroom:

Introduction to Free Fall:  What does "free fall" mean?  Does this motion show constant velocity or acceleration?

Acceleration due to Gravity:  What is the symbol and value for acceleration due to gravity on earth?  What is the initial velocity for a dropped object?  What is it's final velocity after 1s? after 2s? after 5s?

Make a new folder in Notability called Free Fall for any notes that you take.

Weekend HW

Happy long weekend!  Your HW is to do "Graph Sketching HW," located in the folder.  Use the graphing hints we discussed in class.

Looking ahead, you will have a quiz coming up on the following topics:

1. Reading d vs t, v vs t and a vs t graphs
2. Sketching d vs t, v vs t and a vs t graphs
3. Solving problems using a = vf-vi/t

That quiz will be on Wednesday for Galileos and Einsteins, Thursday for Newtons.

The Physics Classroom reading and notes

The sections are on different HW assignments because of the missed day last week.  Please check your assignment carefully.

Galileos and Einsteins: your HW is to finish the Cars on a Ramp lab, including the two graphs and questions.  That is due Wednesday.  What is described below will be your HW for Wednesday night (due Thursday).

Wednesday night: Galileos and Einsteins are doing the reading below.  Newtons should review the information and make sure they are familiar with the terms listed below.

HW is to read two sections in the Physics Classroom.  Go to Physics Tutorial, 1-D Kinematics, and read sections 1d and 1e (both in Lesson 1, they are 1d Speed and Velocity and 1e Acceleration).  During the reading, pay attention to the following:

• the difference between calculating speed and calculating velocity
• the definition of average velocity
• the difference between average velocity and instantaneous velocity (it describe average speed and instantaneous speed but its basically the same thing)
• the definition of acceleration
• the equation to calculate acceleration
• the units for acceleration

Cars on a Ramp

If you did Cars on a Ramp today (Galileos and Einsteins Monday, due Wednesday, Newtons TBD), your HW is to finish the lab packet including the two graphs and the questions.

Displacement vs time and velocity vs time graphs

Thursday will be Day 3.  Friday will be Day 5.  

If today you did the Graph Matching (Galileos and Einsteins Wednesday, Newtons Thursday Galileos and Einsteins Thursday, Newtons Friday) your HW is to do the "Reading Motion Graphs HW."  Use the chart of notes we took in class today.  When you are finished turn this into your Drive folder.  Due Monday for everyone.
