Newton’s First Law

Newton’s Second Law:

Something to think about:

Using the image above, try to describe (in words) what happens to M1 as M2 falls. Don’t just say it moves forward. Think about what goes on with its motion. Also, consider Newton’s Second Law (Fnet = ma).

Then, think about what happens to M1 when M2 hits the ground. Think about how M2 hitting the ground might affect the forces in the situation. How might it affect the acceleration(s)?

Finally, for a real challenge, try to calculate the velocity of M1 when M2 hits the ground. Assume the position of M2 in the picture is the starting place (otherwise known as the position at t=0). Yes, you will have to use kinematics. Yes, kinematics will show up on tomorrow’s exam.

Example Problem: (Repeated from a previous lesson)

Post-reading question: If you run 300 meters north and 400 meters east, what is your displacement? Be sure to include direction, since displacement is a vector.

Worked example for convex (converging) lens: Pay more attention to what he does than to his explanation. He uses some strange terms for the rays he draws, but you should be able to easily match what he’s doing to the rules I gave you.

Start here. Note that this video comes up again at the end. You DO need to watch it twice. You have been warned! Bwahahahahaha!

Next, read “Introduction,” “Temperature Scales,” “Physical Changes Due to Heat Transfer,” “Calorimetry I” and “Calorimetry II” on pages 157-159 of the Princeton Review book. Try example 9.1, and make sure your solution matches theirs.

Now, watch this

Calorimetry and latent heat

Next, read “Thermal Expansion” on pages 159-160. Try example 9.2, and make sure your solution matches theirs.

Now you have reached the only assignment due for credit: Work this problem as if it were a whiteboard problem, drawing diagrams and explaining where necessary. If you need help, the last video is most like this problem. If you still need help, scroll down to the quiz review material.

Problem:

Draw out the PV Diagram for the scenario below and it will help you answer the problems.

A gas starts out at Point A at 400 K. This gas is also initially at a pressure of 1 x 10^5 Pa and a volume of 0.001 m^3. The gas begins to expand (increase volume) isobarically to Point B until it reaches a volume of 0.004 m^3. The gas then contracts (decreases volume) isothermally to Point C until it reaches the original volume of 0.001 m^3. The gas then finally decreases its pressure isovolumetrically back to the original pressure of 1 x 10^5 Pa at Point A.

Calculate the temperature at Point B.

Determine the temperature at Point C.

Calculate the pressure at Point C.

Determine the internal energy (Delta U) for the process from B to C.

Determine the work done on the gas for the process C to A.

Calculate the work done on the gas for the process A to B.

What does the area under the entire cycle in the PV diagram give you?

Is the heat (Q) absorbed or released for the process of C to A?

Calculate how many moles of gas there are (use R = 8.31).

If you could have one superpower, what would it be?
