First Law of Motion: Objects in motion tend to stay in motion unless acted upon by an external force. Force is a push or a pull, like pulling a wagon or pushing a car. Gravity is a force that attracts things to one another. Gravity accelerates all things equally. Which means all things speed up the same amount as they fall.

What happens when you kick a soccer ball? The ‘kick’ is your external force. The ball will continue in a straight line as long as it can, until air drag, rolling resistance, and gravity cause it to stop.

  1. Yes, all of the sections in the High School physics section have these for you to download. Enjoy!

    I really like the workbook and want one for all the other sections too please:)

  3. The workbook I made for the first section (Kinematics) was a trial test sort of thing… I basically took the content that is already on the site and compiled it into one download. I haven’t heard feedback whether it’s helpful or not, so I have not yet put together any others for the successive sections/chapters. The content is already on the website next to each experiment, but it’s not all in one download file.

    Is there a workbook for the 2nd unit (newton’s laws) of the physics class

  5. I’ll have my team connect with you right away!

    I am paying $57 a month for my son to take the physics class. He has been able to access all the content until today. The credit card is valid and is being paid monthly. Now we are getting messages that says “Sorry, but it looks like you don’t have access to the rest of this content” He had access until today. What happened? This needs to be fixed quickly because he is trying to stay on schedule with the content as we have outlined with him. Thanks. Gary Cardinale
