      • Encouraged to us Mrs. D. Gende's review site with practice mc questions from the Walker text book.
      • Official Start = 5pm, (you are welcome to come in earlier if you would like).
      • Official End = 7pm. (maybe a few extra minutes, but not too crazy much).
      • We will review some of the AP Produced Sample M.C. questions.
      • We will review some vectors & how they relate to mechanics & E&M probs.

Prom Physics

This extra credit opportunity is designed to show you how physics is everywhere, and can be PHUN!
You may choose several of the items below. The more impressive, the more credit.
You must have eyewitnesses and pictures to get extra credit. (Must have evidence!)
You must write about ½ page about the physics, your experience and reactions of others. Turn the assignment in within one week of your prom.
1.Singing glass
. Using stemmed glasses, make beautiful music by rubbing the edge of the glass and causing resonance vibrations. Use multiple glasses with different amounts of H2O to get different notes.
Beats. If there is live music, ask the guitarist(s) to slightly mis-tune their instruments so everyone can hear the beat frequencies.
Nodes. Find a spot on the dance floor where the music is noticeably quieter because of two speakers canceling each other out. If the floor itself vibrates from the dancing, look for nodal patterns there, too.
Sound waves through table. Have your date place her ear on the table top and play him/her a symphony with a comb scraping the edge of the table, tapping spoons on plates, glasses, etc.
Spooning. Hang a spoon from your nose to demonstrate friction and center of gravity. Tell your date about the images formed in the opposite sides of the spoon. Which is convex, which is concave? Real or virtual?
Ice show. Observe the buoyancy of the ice in your drink. Explain how the densities of the liquid and the ice are different, and how forces are involved in creating the equilibrium condition. Try with multiple liquids and observe how high/low the ice floats.
light waves. Hold your fingers together and look through a very narrow slit to see diffraction and interference patterns from the light. Describe what you find from different light sources.
Static cling. Rub a balloon on your hair and get it to stick to the wall. Observe and explain to your date the attraction between the balloon and your hair, and the attraction (by polarization) between the balloon and the wall.
Spiked heels. Explain to your date how spiked heels on the dance floor (or your hand) create a greater pressure (P=F/A) on the floor than flat shoes.
Spud show. Use a baked potato and forks to create a center-of-gravity balance toy.
Free-fall. Drop a dollar bill through your date's fingers and challenge them to grab it before it falls (fingers start by George's face). Explain the Dx= ½gt2 time is greater than human reaction time.
On the bus/ in the car. When your date slides across the seat toward you when going around corners, explain the concept of inertia.
Mooning. During a romantic moment, find the moon and explain to your date why the moon's phases change. Explain how Newton realized that the moon is actually freely falling towards the earth just like an apple or astronaut.
Lever launch. Set up your spoon as a lever and place a small piece of paper in it. Rapidly apply a force to the other side and explain how your work input to the lever caused it to do work on the paper and give it kinetic energy. Observe the projectile motion of the paper (don't get in trouble!)
Parabolic fountain. Make an excuse to go get a drink of water from the fountain. Get a picture of the parabolic shape of the water stream and explain how the forward motion and the gravitational acceleration combine to produce the parabola shape.
Swinging. Strut your stuff on the dance floor. Show how angular momentum, is conserved (remember the ice skaters spinning). Try break-dancing, limbo, or square-dancing. All have physics potential.
Distorted vision. Bend a plastic mirror to distort your date's appearance. Try looking at your date through your water glass.
Terminal velocity. Turn your program into a helicopter and see who can get theirs to stay in the air the longest.
Cool shades. Find out who's shades have polarizing lenses. Look at the light reflected off the mirror ball, or off a lake, car hood, etc. Explain to your date how they can remove glare or keep you from reading your digital watch.
Flush. Observe the coriolis effect after flushing. Does the water in all toilets spiral the same way when flushed? Get your date to help you.
Shock your date. Pay attention to the static electricity at the prom, or getting in and out of your car. Shock your date and explain the physics of charge buildup. Explain that opposites attract.
Spark your date. Find a dark corner with your date. Open your mouth wide and chomp down on a wintergreen lifesaver. They make blue sparks (and freshen your breath).
23.Dime jumper. Place a dime on the table, blow a steady stream of air horizontally across the top of the dime. You can get it to jump up onto a plate. (Bernoulli's principle)
Full glass. Fill a glass of water to the very top (no ice). Note that you can add a little bit more and the water does not spill out. It can be filled above the rim because of the surface tension and cohesion of water. Now try filling a glass of ice water to the brim. Note how far above the rim the ice sits. Predict what will happen as the ice melts.
Your own ideas? Come up with your own demo of the hundreds of things we have learned. Keep it safe and legal.
Enjoy your prom, be safe and smart**.
Remember, physics can be your greatest friend. Use it wisely.
