The Physics of Shooting Someone Out of a Cannon

Despite popular belief, the cannons that are used to shoot people high into the air does not use cannon powder. Instead they used compressed air to project the person forward. When the cannon is fired, a sled that is in the cannon shoots forward and stops at the top of the cannon at a force of 3,000 to 6,000 pounds per square inch. The person of course keeps flying forward into hopefully, a safety net. When setting up the cannon a few things need to be considered: the wind speed, temperature, body weight, distance, and obstacles. If you ask a human cannon they’ll tell you that landing is the real danger.

The trouble with landing is that the nets although measuring about 50 meters; it is still a small target for a person to land in. As the landing space is about 50 meters, everyone who is involved with the stunt needs to constantly measure the wind speed. If they do not, the person will fly off course and will end in a fatal accident. Body weight is also a huge contributor. If the person is even a pound off, it will totally throw off the projectile of the launch. The most important part of the whole launch is checking the person over when they come down from the launch. It’s common for the person to have bumps and bruises when they land. It is also possible for them to have broken some bones. The force of the cannon shooting off can buckle legs and fracture and break bones. Before getting shot out of a cannon, the human cannonball must be taught how to stand in the cannon and handle the pressure of being shot out of a cannon. The legs must be in a locked position because of the force of the initial force the cannon exerts on the person. If the person’s legs were not in a locked position, the board at the bottom out shoot up and the person’s legs would buckle, causing them to veer off course sending the person flying to their death.

Another thing the person needs to worry about is the g- force. When being shot out of a cannon, the person has to accelerate quickly to reach the landing zone. If the person did not train properly to handle the pressure of g-forces pushing down on their body, they might black out, and miss the landing zone.

The Physics of Angry Birds

How does physics connect to the game app Angry Birds? Well, physics is all about the broad field of science having to deal with nature and the properties of matter and energy. It is based off the seven branches which are mechanics, thermodynamics, waves and vibrations, optics, electromagnetism, relativity, and quantum mechanics. Mechanics focuses on the motion and interaction between objects. Thermodynamics is based off the study of temperature, heat, and energy. Waves and vibrations is based off the study off sound, electromagnetic waves, x-ray, and light. Optics focuses on light, lenses, mirrors. Electromagnetism is all about electricity and magnetism. Relativity is the relationship between speed, time, and mass at extreme conditions. Quantum Mechanics is the behavior of subatomic particles, especially electrons. Angry Birds is the most addicting app that was launched in 2009 by a guy named Rovio Entertainment for the Apple company.

The whole concept of the game was created by Jaakko Lisalo from Finland and the designs were by Markus Tupperainen and Peter Urbanics. The main synopsis is that the pigs are stealing the birds’ eggs causing them to get very angry and turn the wingless birds into the pig structure to demolish them. At the time of development, there was a swine flu outbreak. There are many different versions of Angry Birds and can be accessed on the computer, tablets, smartphones, and iPhones.

Angry Birds play a part in physics because of the calculations into finding the velocity and distance. Velocity is the rate of an object changing of displacement and it tells the magnitude and direction that the object is moving. When the bird leaves the catapult, it has a velocity at a certain angle. When it comes to velocity, there are two components which are the vertical and the horizontal. The vertical component is based off the acceleration due to gravity constantly pulling the bird down closer to the Earth. The horizontal component is constant which means there is no forces repelling on the bird and there is no friction due to air resistance. The gravity will end up slowing down the vertical velocity to zero and it becomes negative. This mean that the vertical velocity of the bird will decrease from v to 0 upwards. Then increase from 0 downwards. Distance is the total length between two things by a moving independent of the motion.

Now, there are two components with distance which are vertical and horizontal. The distance travels horizontally which means that the time multiplies the constant speed. To figure out the distance travels vertically, the kinematics formula is needed which is w = v + at.

Quantum Physics and Law of Attraction – What Is the Link?

If you have heard of the law of attraction chances are that you have come across mentions of Quantum physics as well. At first impression, these two topics seem worlds apart from each other. But if that is so, then why do people mention quantum physics and law of attraction together, as if there was a deep link between them? Let us have a look at why these two seemingly diverse topics get simultaneous attention and mention.

What Exactly Is Quantum Physics?

Quantum physics is that branch of physics that specifically deals with Quanta. Quanta are nothing but minute or indivisible parts of energy. Quantum physics is based on certain crucial fundamental facts. Firstly, it makes one point very clear that the world of quanta is totally different than the world in which we live. Next, it states that the elementary particles of quanta can exist both in wave and particle form.

There are many other complex matters discussed this subject, but what matters to people like us who are investigating the relation between quantum physics and law of attraction are the strange results of some of the experiments done. The double slit experiment, Copenhagen interpretation and Schrodinger’s cat experiment are the major examples.

Double Slit Experiment

The double slit experiment revealed that particles of energy could exist in both particle and wave form and the mere act of observation by an observer could cause the particles to behave differently than what they behaved previously (without observation).

Copenhagen Interpretation and Schrodinger’s Cat

The Copenhagen interpretation also claims that particles can take a wave form or particle form depending upon the observation. In simple words it means that events can take a turn according to the act of observation. Schrodinger was a physicist who proposed the Schrodinger’s cat thought experiment to explain this better. According to this thought experiment, a cat (presumed) who is enclosed in a box with radioactive counter and hydrocyanic acid could be dead and alive at the same time, with both states being real.

The final outcome of the experiment will depend upon the observation made at the time of opening the box to check on the cat. According to Copenhagen interpretation, the act of observation is the decisive factor that determines the reality of the outcome.

Applying Quantum Physics to Law of Attraction

Our thought processes are a form of energy and the minutest part of this energy is called quanta. We already know that quantum physics states that these quanta can exist either as waves or particles. We also know that the decision of the quanta to present itself as waves or particles is dependent / can be changed according to the act of observation by the observer.

On deeper understanding what we can infer is that our thought processes can project / create a reality, and that reality is totally dependent upon the act of observation by us. Or in more simpler terms we see what we believe / want to see. We create our own reality according to the energy released by our thought processes.
