# Physics 2-13-12 Archimedes’ Princple

PHYSICS: So when you were floating in the pool this summer, did you realize all that about buoyant forces acting on you? 🙂 Here’s the lecture from Monday – an intro to Archimedes’ Principle. Great topic for investigation! Speaking of….just in case you didn’t make it home with the homework for Tuesday night, here’s a copy of the Buoyancy 1 – thLab that is due (on a separate sheet of paper) Wednesday. Don’t forget that you can use any kind of plastic bowl or cup that is small enough to fit inside another bowl that you can measure volume in. Buoyancy 1 – thLab

Good luck finishing up your cars tonight! Be careful if you plan on painting them – paint can act to glue the parts together! And don’t forget to bring a schematic and explanation of how your car works.

Would the length of our torque arm be included in our total length for King of the Hill?

• Ms. Skinner says:

Charlie – I’m going to be measuring from the front most point on your car to the rear most point on your car, and from the left to right, etc., – all before the car is launched. After the launch, it can be any length or width.

2. Jakin D P5 says:

I’m looking forward to the races today.

3. Andrew Felder P5 says:

Will the distance and speed competition be before our king of the hill competition today?

4. Jackson Wofford P5 says:

Do we need to do the problems tonight for homework as well as the take home lab?

5. Megan G P5 says:

Is Fb always the same in every body of water ever, or does it vary?

6. Cory A. P5 says:

Are we going to do a GLX with density?

7. Matthew D P5 says:

Does gas have buoyancy?

8. Kamren J P5 says:

I’m a little unsure on rearranging the buoyancy equation.

9. Sebastian G P5 says:

Ms. Skinnner,

For a submerged object, the water pressure is acting on both the top and the bottom of the object?
