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.

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).

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.

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.

(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

(Reference) It doesn’t matter whether the volleyball is being set, served, or passed, it moves both up and forward. This is influenced by the downward pull of gravity and horizontal motion, which is known as projectile motion. The volleyball serve follows a parabolic trajectory, and without air resistance, the volleyball would travel along a parabola, but since there is air resistance, the volleyball travels along a shorter path. (Reference) there are 3 factor that can increase your volleyball serve however if not performed correctly can affect the serve. These 3 are height of release (the higher the better), speed of release (the faster the better) and angle of release (45° for optimum distance). The higher the height of release, the better but it is better because it means the ball travel lower which means the ball is not in the air for long which is harder for the opposition. Generally, the greater the speed of release, the greater the distance gained, the speed of release can improve because it will be more challenging to return. The angle of release improves the accuracy of the shot, which can also make the serve harder to

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

This then makes contact with the ball and some momentum is being transferred into the ball where it begins its flight path. - Stability and Balance - The front foot takes a step towards the target which then increases the size of the base support. So as you execute the shot, the center of gravity still remains within the base of support keeping you stable and balanced with the execution phase. -

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

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

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

When the ball hits the ground then y = H (since the positive y axis points downward.) By measuring the distance of fall and using that acceleration due to gravity, g, the time of flight t = Tflight, can be calculated with the following transformed kinematic equation:

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.

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
