Physics 1-12-22 Collisions Problems Review 2

PHYSICS: Great job with some of the more advanced momentum and energy problems! Here’s a look at the student in the middle of a frozen pond, bird on the wire, car crash with coefficient of friction, and the billiard balls.

Ready for the test? Take another look at some of the concepts!

Physics 1-11-22 Collisions Problems with Energy & Bouncing

PHYSICS: Great job on the problems so far!! Here’s our look how kinetic and potential energy get involved – dart in the block of wood and the bird on the swing. This cute little bird isn’t on a swing, but he is one I came beak to nose with on a mission trip to Costa Rica!

What about even more practical applications? Hmmmm…..

Physics 1-10-22 Collisions

PHYSICS: Collisions – they’re all around us and they all obey the law of conservation of momentum. Here’s more specific information about the proper way to differentiate and name them.

Great job with the conceptual review and setting up the problems! As you practice tonight, be sure and check for connections between the conservation of momentum and the conservation of energy. πŸ™‚

Happy New Year 2022!!

Happy New Year!! Aren’t you glad that God gives us a chance to start all over again?

We are going to have an awesome 2nd semester!! I’m praying that God will use this semester to help get you ready for the incredibly wonderful things in has for you in the future!! And more than that, I pray that this year you’ll grow more than any other in your walk with our Lord Jesus. I pray that you’ll be determined to follow Him, no matter if you have to walk by yourself.

I can promise you – Jesus will never forsake you!

Happy New Year!!

β€œAnd they that know thy name will put their trust in thee: for thou, LORD, hast not forsaken them that seek thee.” Psalm 9:10

….”I have decided to follow Jesus. No turning back, no turning back. Though none go with me, I still will follow. No turning back, no turning back.” John Clark

Physics 12-6-21 Ch 5 Review WS #19

PHYSICS: Great job with the power lab today. All I’ve got to say is how in the world?!? You’re also doing a great job with these problems! Here’s our look at #19 from the Chapter 5 Worksheet 2. Would have been helpful, I think, if I had remembered that they didn’t tell you it was at constant velocity.

God bless you as you continue to prepare for the test! I’m praying for you!!!
