Lab Assignment : Projectile Motion

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 ball uses this kinetic energy to move up the usually 6 to 7 degree incline to the top of the playing field. The kinetic

There are not many activities out there that relax and soothe me quite like shooting my bow. It is not as simple as it sounds though, just pulling on the string, releasing the string, and watching the arrow fly towards your target. There are a number of aspects that must be taken into consideration when trying to shoot a bow and arrow efficiently, this is where we will get into the physics of archery.

The physics involved in soccer includes friction, torque, center of gravity, Magnus Effect and Newton’s three laws of motion. The physics of soccer comes from three main parts of physics which is velocity, acceleration, and displacement. Velocity is shown in soccer with the speed and direction of the soccer ball when it is hit or kicked. Acceleration is shown in soccer when the ball changes velocity when it is hit or kicked. Displacement is the change in position of the soccer ball.

1. The ball has potential energy while momentarily at rest at the top of the path.

In light of our final exam, the chuck a duck project, we are to learn about projectiles, trajectory, and the factors that affect these things.

1) Once the simulation opens, click on ‘Show Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around.

In order to make our lives easier, we placed all objects on whole numbers. Our “hoop” was placed at 10 feet, our “person” was placed 15 feet away from the “hoop” and the vertex of our parabola was 21 feet high and 7 feet away from the “hoop”. We did this because it was one of the solutions where the ball could go into the hoop. Doing so, the h value was changed to 7 and the k value was changed to 21. The effect that has on the shot is, it changes the distance from the vertex to the hoop and k effects the height of the vertex. By changing these values it changed the path of the ball, making a successful

The Catcher in the Rye has been long wrung out and decoded, since its arrival on the scene of long-listed literary masterpieces. Every detail, every word and phrase has been carefully placed under a microscope by a scholar in hopes of finding an untouched pattern. The common motifs throughout the novel represent ideas of oneness and isolation, being the catcher and the caught, and the vital representation of foundational opposing binaries. This duality configuration places an air among those who live today; it becomes a fact all must face at one point or another. Of course, one may argue that the choices of opposite binaries does not, in fact, have to place a role in human nature and one may choose an optional gray area, but what is that gray

Ball velocity was calculated for 6 serves, 3 jump serves and 3 standing overhand serves. Ball velocity was calculated based on distance and flight time. Both of these variables were discovered through Dartfish Analysis Software. Table 3 displays the summarized

The sketch below shows the trajectory of a projectile propelled with an initial velocity V0 at an angle 8. Neglecting air resistance the horizontal range travelled is given

Lastly, the launch angle also has a great effect on the distance traveled. If projected at 90° the ball would only be thrown vertically upwards and back down to the person. There would be no horizontal change in position but a great maximum height. The greatest horizontal distance is reached between 40° and 50°. For this reason the launch angle affects the

(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

by, F=P/Dt. By increasing the time over which you decelerate the ball, you lessen the force (Bill Willis 2001). This increase of ‘stopping” time will make it easier to catch and control the ball.

There are many aspects to the game of basketball and physics can be applied to all of them. Although to be good at basketball it is not necessary to play it from a physics point of view. Basketball players become good by developing muscle memory for the actions that must be performed in the game of basketball from years of practice. Nevertheless knowing some of the physics in the game of basketball can help a good player be a better player. In this paper I will cover the three most important aspects of the game, shooting, dribbling and passing.
