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

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.

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

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.
