Reading about Velocity, Inertia, & Newton’s First Law
Click here for a printer-friendly version of this page.
Newton has a famous quote that goes “If I have seen farther than others, it is because I have stood on the shoulders of giants.” One of the giants he was referring to was Gallileo. Thanks to the discoveries of Gallileo and others, Newton was able to make many of his own discoveries. The most famous of which are Newton’s Laws of Motion.
Newton’s three laws of motion predict the motion of virtually all objects on Earth and in space. You are about to know all of them. Newton’s Laws are all they used to launch space craft to the moon and soon you will understand them all. Pretty powerful stuff, eh?
Newton’s Three Laws of Motion are:
1. An object at rest tends to stay at rest, an object in motion tends to stay in motion unless a force acts against it.
2. Force equals mass times acceleration.
3. Every action has an equal and opposite reaction.
Newton’s First Law
At first glance Newton’s first law seems rather obvious. Especially the first part, “An object at rest tends to stay at rest” Well….of course. When was the last time you saw your table move across the room for no reason? Last time you were eating your potatoes did they float off your plate and into the lamp? NO! It’s really the second part that is an amazing statement.
Especially if you consider when the statement was made:

So the bigger something is less velocity pushes down on it like the bowling ball ?
wow what happened? did you not see all the cool stuff you can build and learn? wish i had this program years ago! try another program then if its not for you and leave aurora for the rest of us!
BORING?!? You’re kidding, right?
Well, it’s not for everyone… you’ve really got to be curious about how things work and have time to build stuff and wonder about things. It’s really for kids who like to blast rockets, build radios, create robots from junk parts, wire up laser light shows in tupperware, burn green fire, lift ten friends with one hand using pulleys, build a car that runs on sunlight and water, hear magnetism, build kites that lift you off the ground, generate plasma in the microwave, and learn how to fly real airplanes.
If you’re looking for a quick-study to pass a test, or for cartoon entertainment, you’ll have to look elsewhere. If you’re more into another subject, that’s totally fine… just have fun no matter what excites you. Best wishes!
Your program is boring.
The three laws are listed on this page – do you see it? You should find this text:
Newton’s Three Laws of Motion are:
1. An object at rest tends to stay at rest, an object in motion tends to stay in motion unless a force acts against it.
2. Force equals mass times acceleration.
3. Every action has an equal and opposite reaction.
Newton’s First Law deals wit motion, so you’ll find info for it in the Velocity Reading section. Since Laws 2 & 3 deal with acceleration, you’ll find them listed under Acceleration Reading.
The Lesson Plan covers the reading all the material from all lessons within the unit, so that’s why you found it there. The “Printer-Friendly Version” link also includes reading from all Lessons for convenience. Just note that each Lesson on the website has its own reading section. Does that help?
Where is the write-up about the Second and Third Law?… When I print out the Lesson Plan, the First, Second and Third Law stuff is there…but here on THIS web page, only the write up on the FIRST Law is here…so I can access the material, but only through the Lesson Plan and my kids LOVE to read your stuff on the web. What am I missing?
Thanks
The PDF for k-8 reading is here under “Step 4: Read Read Read!” and it’s also listed near the bottom of the page under ‘Reading’ for both Velocity and Acceleration.
Help please. . I can’t find the pdf form of the K-8 reading for Unit 2.
The shopping lists are in the GETTING STARTED link in the pull-down menus for the different units. Here’s the direct link to the one for unit 2:

Where can I find the printable version of the reading for Unit 2. I found it for Unit 1, but can’t seem to find it for unit 2.
