Physics: The Chuck A Duck Project

Objective: Using a marble launcher, launch marbles from different angles with different forces to find the maximum height and the velocity as it leaves the launcher. Using different variables and results to determine how the different angles and amounts of force effect the variables. With this data show the effect the forces cause in 1-D and 2-D motion, as well as in the X and Y directions. This is done through kinematic equations and calculations.

In football the force of impact can be dangerous. Helmets are constructed to protect the brains of the players. Without this protection the player will receive major damage from the impact of the force. In this lab, students will construct a device that will protect an egg from the impact force from the drop. The egg acts as a substitute for the brain and the device is the “helmet” for the egg. The independent variable of this experiment is the trials; the dependent variables of this experiment are time and velocity. By using the laws of physics, students will construct an efficient device that will protect the egg from the harsh impact of force.

The air also affects the flight of a soccer ball. In the air there are little particles known as air molecules. They move around at a certain speed and the amount of air pressure comes when the air molecules are forced against a certain object (NASA, 2004).

This report shows the effects of weight distribution has on the flight distance of a paper airplane. Just like with real airplanes, paper airplanes rely on aerodynamics to get the airplane to fly, although, they may not look or fly the same they use the same. Changing the postion of where the weight is distrubuted on a paper airplane can affect the planes ability to fly as far.

During this lab, my partner and I had to figure out what our variables were in order to start the tests. Our independent variables were mass, surface area, height, and the force applied. Our dependent variable was the amount of time it took the object took to reach the ground. Lastly, our control variables were the type of object, height, planet, force, temperature, and air resistance.

(Melvin, Mangonel - “Physics of Catapults”) The speed and distance of the projectile depended on how much force the catapult applied to the projectile, and the momentum depended on the mass and the velocity of the projectile (dead diseased cow, or flaming

This weeks material covered Parallax, to be more specific, what it is, how it affects the relationship to the point of aim towards the point of impact, and a general layout for most scopes(Leupold). At this point I will cover what exactly Parallax is.

In “what is a projectile” (Physics Classroom, 2015), a projectile is a moving object and the only force acting upon it is gravity. The actual path of a projectile could vary according to the position and direction of the launch of the projectile.

One of the most important factors in my own and many other peoples opinion is the launch angle. The launch angle controls how high and far it will launch whatever you put in it. This is very important because when you have all different things to launch the size and weight will determine how to tweak the angle to maximize the success. “Using Physics and Mathematics you can estimate the distance the catapult can shoot. If you have experience in these topics you can go here to see how the equations are formed. If not, that’s okay!”(Catapult

The velocity, or speed, in a cannonball during the 19th century varied greatly. It all depended on the angle degree the cannon was facing, the size of the cannonball, and many other things. Air resistance and gravity also played

There is no force acting on the rocket yet. When the rocket is ready to be fired, the thrust increase from zero and the weight decrease due to the motor burning out. The weight of the rocket balances out in this is where the three law of motion reactions on the earth weight. When the engine thrust is greater than the weight, the net force goes up and the velocity increase from zero. However, if the thrust is equal and the drag, the velocity is

As written in this essay, you will learn if balanced or unbalanced forces cause a change in velocity. By many articles and life examples, this essay will defend and evaluate the claim using evidence and reasoning on why unbalanced forces cause a change in velocity. The claim will be supported by a law of physics, a textbook excerpt, and the process of skydiving.

The introductory chapter of John Allen’s Aerodynamics: The Science of Air in Motion describes a complex interaction between the object the the air in motion around it. He explains that the

The concept of air resistance simple. It is a force created when an object moves through air particles suspended in the atmosphere. Because these particles have a mass, there must be a force needed to move each particle out of the way. Even though the force needed to move each particle is minuscule by itself, the sum of the forces for particles can greatly influence a flying object. On page 69 of The Science of Everyday Things, the author writes about drag forces and air resistance by stating, “In the real world, air resistance creates a powerful drag force on falling objects. The faster the rate of fall, the greater the drag force, until the air resistance forces a

In chapter 5 page 84 of the book Physics for Game Programmers by Grant Palmer, projectile physics is discussed. For our groups tower defense game, we believe implementing the gravity-only model is the best fit for our game. We
