Bowling Ball From Ceiling

Contrived 

Here we have our glorious leader showing of the mystical powers of force tension in our physics classroom. We know from previous lessons that force tension is created with a combination of mass of an object, a force of gravity downward, and the tension from a line upward. Through creating a free body diagram, one can u derstand that the downward force of gravity is currently underscored by the upward force of tension created by the yellow rope allowing it to hover in place.

Cruising Altitude

Natural

In the photo below, I am in a plane at cruising altitude over San Francisco. Relating to physics, a tougher has a combination of physics forces acting upon the plane mid fought. With a force of gravity acting downward, the velocity of the plane in the direction it is headed, air resistance, and all the other minor details create the physics behind flying a plane. Also, mapping out the directions of the forces makes complete sense on a physics level because from what we learned, we know it is true.

Force From the Quad

Natural

Below is an instance of our quad broken down to a more thourohg physics level. Surrounding the B, there are small metal fence posts surrounding. From just a glance you'd think it is nothing more than that. But your wrong. Physics has a hand on everything in life as we know it. On a closer leve, there is gravity aling with a normal force acting upon this post. As the gravity acts downward theoretically pulling the object down, a normal force is acting upward completely counteracting gravity allowing for the post to not fall through the earth.

Light Distortion

Natural

Below, I a photo of a glas in which a small glass bubble is located. We have not yet learned that refraction occurs as light passes across the boundary between two media. But refraction is merely one of several possible behavior boundaries by which a light wave could behave when it encounters a new medium or an obstacle in its path. The transmission of light across a boundary between two media is accompanied by a change in both the speed and wavelength of the wave. The light wave not only changes directions at the boundary, it also speeds up or slows down and transforms into a wave with a larger or a shorter wavelength. The only time that a wave can be transmitted across a boundary, change its speed, and still not refract is when the light wave approaches the boundary in a direction that is perpendicular to it. As long as the light wave changes speed and approaches the boundary at an angle, refraction is observed.

Physics Behind the Lab

Contrived

Just from a day ago, we did a glorious egg lab to understand the undertones of the physics behind dropping an egg from the ceiling down to a contraption set to cushion it's fall and save it. As we drop the egg from the ceiling, a certain amount of downaed force due to the weight of the egg and the velocity. When it comes to the landing pad created by each group, we were tasked with figuring out a solution for the falling egg. The physics behind that is understanding what combination of supplied objects can create enough counter action to allowing for the life of the egg to live on.

Rocket Report

Materials:

2 two liter doctor Pepsi bottles ~ $5

1 roll of black DuckTape ~ $2

1 cardboard box for wings ~ free

1 pair of scissors ~ borrowed

1 thick paper for nose cone ~ free

1 large plastic bag ~ free

4 long lengths of string ~ free

A lot of cotton balls ~ free

1 egg ~ provided

Step 1: take you first bottle that will be the capsule for water, set that aside.

Step 2: grab your second bottle and cut it directly in half in regards to the middle of the bottle.

Step 3: take your card hard and cut out three identical wings

Step 4: align all wings equidistant from each other on the bottom bottle

Step 5: thoroughly DuckTape until wings have immense stability

Step 6: take the top bottle and fold thick paper into come shape and tape it to top

Step 7: cut holes into your paper bag and thread the four strings to create parachute

Step 8: DuckTape the four ends of parachute to inside of top bottle

Step 9: place cotton balls into top of top bottle and secure them

Step 10: place egg on bed of cotton and secure it

Step 11: fold parachute like an accordion and stuff it into bottle

Step 12: connect both bottles

Step 13: fill bottom bottle with 1/3 to 1/4 full of water

Step 14: correctly set up for launch

Step 15: murder your egg

As we prompted to launch our rocket with confidence everything went according to plan up until it reached its peak. Assuming both bottle would decouple at its peak was very wrong. Due to the upward force, the bottles were lodged together and were unable to separate. If everything would have gone according to plane, the battles would've decoupled allowing for the parachute to deploy and bring the egg safely back. But as out rocket was still in one piece as it began to turn back towards the ground, it started its decent to the death of our egg. All we could do now was watch our rocket plummet back towards earth looking like a nuke descending on the school. On impact, we knew we were murders. Seeing the initial impact with the ground and the the six foot high bounce that followed we were reluctant to see the damage done. As we proceeded to unravel the news we found compete mush in our capsule and expect to hold trial in egg court for our heinous crimes.

IV.

Knowing that our problem stemmed from the lack of separation one huge thing that we should have probably reevaluated was our upper bottle or capsule. Thinking about it after the fact makes me come up with new possibilities. Rather than relying on the top bottle to separate from the rest of it, we could have something different. Something along the lines of creating a an actual capsule that simply gently rests on the top of the rocket and and a higher chance to fall out a deploy a parachute would have been a much wider design to go with.
