Today in Physics....

We went over the questions in the green textbook, and then we went over the review for the test tomorrow.

Reminder that the exam is on the 28th in the afternoon. STUDY STUDY STUDY!

The scribe for tomorrow is...sandy!

Today in Physics....

We watched a video on weightlessness and took down fifteen points about the movie, which we were to hand in to Ms. K.

We then went over the review for the test which is on Thursday. It has been uploaded to the blog.

Tomorrow's scribe is.... Van!

And you better be in class tomorrow...it's bad enough i had to blog for you today! just kidding

Today in Physics...

We went over the Momentum/Football worksheet, the Conservation of Momentum worksheet, and corrected questions 51 and 52 from pages 308 and 309 in the duck book(not the green text book).

We then started learning about projectile motion...

We studied an example involving a projectile falling off a cliff. The path that the projectile travels is called the trajectory. The horizontal distance the projectile travels is the range. The X(horizontal) component is moving at a constant velocity, while the Y(vertical) component changes it's velocity due to gravity. We use these equations:

Velocity of the X component : v=d/t
Velocity of the Y component: a=v/t or v₂=v₁=at or d=v₁t+1/2at² or d=(v₂-v₁/2)t or v₂²=v₁²+2ad

.....but, in this case the acceleration is due to gravity, so you can replace the "a" with a "g", and we all know that g=9.8 m/s²

Then we worked on a short lab involving the pushing of coins off a table with a ruler. Those labs were due today.

We also got a study guide that we will have time to work on tomorrow in class.

The Scribe for Tuesday's class is.......victor!
