Explain How Different Weights And Launch Angles Affect A Projectile

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.

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.

There were many opportunities for error within this lab due to the procedure the group decided to follow. However, the percentage error was not very significant, with a 1.12% to 6.71% difference between the actual and predicted velocity. The slight difference between the percentages could have been a result of parallax, instrument resolution, environmental factors, and the lack of trials. Once major source of error was the group’s decision to bypass collecting many data trials in the interest in time. This may have introduced biased sample fallacy into the conclusion because there were only two trials per a flying toy and which was little evidence to support the statements made about the relationship between velocity, acceleration, and circular motion. For the next lab, the group plans to conduct at least three trails and then use the average to avoid this bias. Environmental errors present during this lab included classmates walking into the flying toy while the group was collecting data,

Some of these factors are gravity, the air resistance, the speed of release, the angle of release, and the height of release. The most basic and principal factor acting on a projectile is gravity. Gravity affects every object. It decreases the height that a projectile can attain. Air resistance is also a key factor working on an object. The larger the surface area, the more air resistance will affect a projectile. Air resistance will also affect an object more if it has a smaller mass. Also, the faster the speed of the projectile, the greater the air resistance. The speed of release refers to how fast an object is released and is directly related to the distance of the flight. The greater the speed of release and object has, the greater the distance the object will have. The initial vertical velocity increases the height of trajectories, creating a longer flight path. Similarly, as the initial horizontal velocity increase, the longer the length of flight and distance. The angle of release is the angle that an object is thrown or hit into the air. It changes the relationship

In the first experiment, “ How does mass affect your game?” it shows that the data on “Ball- Mass 3” that the 10 pound bowling ball had the highest kinetic energy of 27(J), the greatest velocity (m/s) of 3.42, and in average it produced 4 bowling points. According to the data, on “ Ball- Mass 1” the 11 pound ball got an average velocity (m/s) of 3.14, the kinetic energy of 24 (J), and the average bowling points of 3. On the other hand, the evidence shows that the 12 pound bowling ball in “ Ball- Mass 2” has the velocity (m/s) of 3.12, the kinetic energy of 23 (J), and the average bowling points of 4 . Concluding that in my Game 1 the velocity of the masses of the bowling balls decreased when the bowling balls were heavier and that the kinetic energy was lower as the mass increased in the bowling balls.

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

For example if the fulcrum was to be to close too the lacch it would most likely hit the ceiling. Also, if the fulcrum was too be too far from the launch it would also hit the ceiling. The best location for distance when launching the snowball was 3 fifths of the beam away from the launch. This location made it too where the snowball gets distance and some height so that the snowball doesn't hit the ceiling and comes back down and goes really far but luck wasn't on our side for the competition. 2.Explain how the speed of the effort and the amount of effort applied changed the flight of the snowball.

The first one It started to react as soon as I put the paper towel in the canister. it started to fuzz a little when it popped it launched 545cm. The second one I tilted that one more up than usual and almost hit mrs.smith it launched 484cm. Third I put it in more faster and pointed it more straight it went really fast and fell out of my hands it launched at 572 cm the average I got was 533.6 repeating.

Firstly, the weight of the golf ball being thrown affects how far and how high the ball will travel. Since gravity has a stronger pull of the heavier object and a weaker pull on lighter objects, the heavier ball requires a much greater initial velocity to travel further whereas a lighter ball requires a lower initial velocity. This is proven in the data because the lighter the ball, the greater the distance traveled.Secondly, the launch speed will affect the horizonal and vertical distance because the faster the ball travels the greater the distance traveled. Since speed is measured in meters per second and the distance traveled depends on the time, the ball will land further away if the velocity is greater. the data proves the theory that greater the initial velocity, the further the ball travels.

The purpose of this experiment was to determine if rubber bands or bungee cord would put more force into the launch of the catapult. The experiment was designed to test the hypothesis if either a bungee cord or rubber bands would help an eraser to launch further, because of more force.

(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

Let’s also go over some of the technical information you’ve given me. One end of Bobo’s cannon is three feet off the ground and the whole cannon

* The relevance of this experiment is similar to understanding a real airplane. Paper airplane models are derived from an actual plane these days. The design of an airplane has so much to do with distance, hang time, speed, and many other factors. Understanding the models I have chosen to make help me

Step 9: Because we measured the lengths in centimeters rather than meters, we need to calculate are ‘g’ value into m/s2 so we can compare it to the SI unit for acceleration due to gravity. (Eg. 981.4/100 = 9.81 m/s2)
