Human with wings flies

Here is a video of several humans who have small wings and are learning to fly. They land using parachutes.

What is the period of your home planet?

Click on the video to see where you live and help you figure out the period (Time to make one revolution) of your home world (Earth)

Drag Race Video

Which is faster, a 1972 Datsun (early Nissan) or a 2009 Corvette? After watching the video explain on paper the performance of the White Zombie in terms of the second Law F= mA. Also, analyze the drivers statement that his car "did not contribute any emissions to the atmosphere". How is this true and not true at the same time?

Karate chop video

Directions: Please watch the video and then write down a hypothesis to explain the results.

Relative motion on an escalator

Watch this video and then answer the question: What is the lady's motion relative to the Earth and why?

I Movie Tutorials (Importing and Editing)

Your video game project is required to be done using I Movie. For lab this week you will demonstrate understanding by doing two actions after viewing the two tutorials. View the tutorials as many times as needed and then go about creating a short movie to practice the skills you learned. You must click on "Import/Organize Video" to view the first tutorial and then click on "Precision Editor" for the second

1. Import and Organize at least two video clips

2. Trim the clips using the Precision Editor

Myth Busters Rocket Sled Video

Directions: Watch the video in realtime (Not slow motion) and record the time period for the sled from stopped to just before impact. Combine that with the stated top speed in the video to calculate the acceleration rate. Show the calculation on a clean sheet of paper that will be handed in by the end of the period.

Adding Vectors Practice Problems

Directions: Follow the link to the vector problems. Draw each vector to scale on paper with proper direction and find the resultant. You may check your work with the answers link, but you must show how you arrived at the answer to get credit.

So you think you can drive?

You are traveling at the 25 mi/hr speed limit and you see a child jump out into the street chasing a puppy 13.0 meters away. Once you hit the brakes it will take 2.1 sec to stop the car. Using your personal reaction time from the ruler test (around 0.20 sec) figure out if you will hit the child and puppy.

You may use your laptop to lookup any conversion factor, ie meters to miles. Hint---There are two calculations here! You may work with a partner, but both people must show their work. I will come around to check.

Projectile golf game

Open up the golf game and using a maximum velocity of 60, find the best angle to make the ball go the farthest

How quick are you? The Ruler Test

Click on the link and follow the mini activity using a ruler and a partner. At the end use one of the formulas from page 58 (CP PHYSICS) to tell me your reaction time.

Car crash footage

Go to the site and select two radically different types of cars for front crash test viewing , one with a short front end and one with a really long front end. After viewing both videos be prepared to answer the following question: Who has a better chance of survival and why? Use the words displacement, speed velocity and acceleration in your answer.

Smart car crash

There has been a lot of interest in Smart Cars and questions about safety. Watch the video here and be ready to comment about displacement, velocity and acceleration.

More help with Dimensional Analysis (Not for Conceptual Students)

Here is another tutorial on DA with physics units. This is required for anyone who received less than 80% on the CP Physics Quiz 1 Shockwave software is required to view the tutorial. See tech if you don't have it or seek out another tutorial.

Skydiving at Sunset

Ok, so the music may not do it for you but watch the video and be ready to discuss displacement, speed, velocity and acceleration.

Real World Conversions Tutorial

I never knew so many people died from bad conversions. I wonder if this could happen to me? ......Nah! This tutorial on conversions is written for Nursing students. Solve the first 5 problems from the test showing all work and keeping track of units. If you need a conversion factor try the link or go online.

King Henry based Metric Conversions Tutorial

Here is the King Henry Conversions Method Link I recommend knowing this as a backup to dimensional analysis

Powers of Ten Video

This is old, but powerful. Scroll down a ways to get to the video. It's ok to use headphones. Try and pause every power of ten to digest the scale. Here is the link.

Tutorial on Significant figures

Here is the link: http://www.chem.sc.edu/faculty/morgan/resources/sigfigs/

Please use the tutorial and other web based sources to understand how to use significant figures. Why you ask? Knowing what you don't know (uncertainty) is a benchmark for strength and good judgement.

Ex. Your car gets 30 mi/gal and you need to go 320 mi. Loading (measuring) 11 gallons into the tank will only sometimes get you there. huh?

Link For Student and Parent Identification

Here is the link. This is also due by Friday.

Welcome Back to Dayton

It's great to have everyone back. Please bookmark this site as I plan to use it. I look forward to working with everyone, particularly students and parents who have never shown an interest in physics. There is much to discover! Your assignment for tonight is to create a google account at http://www.google.com If you have a gmail account then you already have a google account and may use it. Creating a Google account does not mean you have to use G mail. You may continue using your preferred mail server. However, I will be checking that you have created a Google account. We will be using the account and the google applications throughout the school year. Once you have created your Google account fill out the Google Form that I will post below. Thanks and I am looking forward to a great year!

Sincerely,

Mr. Davison
