Problem: how does the angle of trajectory effect the horizontal distance of a bottle rocket Background research: When an object is in the air and has no forces acting on it other than gravity it becomes a projectile. (Henderson, 1996) Gravity causes the projectile to accelerate toward the ground in a uniform arc like a rainbow does. this shape is known by scientists and mathematicians as a parabola, and objects that fly in the shape of a parabola are said to be in parabolic motion. A projectiles…

The four fundamental forces have been around before mankind. These forces shape the way we live and interact with the objects around us on a daily basis. These forces are so important, they are in existence throughout the entire universe. Black holes, the formation of planets, galaxies and stars are all because of gravity and these same celestial bodies have their own electromagnetic forces and the strong and weak nuclear forces are. Since everything in the universe is made of atoms, there is…

Temporal outliers are common trajectories that follow the populated route, but with an important difference of the speed compared to the other common trajectories. For extracting such type of outliers, we make use of the average speed used by the moving objects in the populated route, we make comparison between each sub-trajectory from the common trajectories and the average speed for all common trajectories that traverse the same route with some tolerance, and we extract two essential types;…

1. What is the GPS Standard tied to this project? The GPS Standard tied to this project is - S8P3. Students will investigate relationship between force, mass, and the motion of objects. 2. How does your rubber band car show Newton’s 1st Law of Motion? The first law states an object will stay at rest until acted upon unbalanced force. The car is at rest until the rubber band is twirl all on the stick. This mean a force has to be added for the rubber-band car to move. 3. How does your rubber…

In the following, I will argue that Einstein’s discovery of the theory of special relativity was ultimately positive in terms of its benefits. First, Einstein’s discovery changed our understanding of space and time. Second, Einstein’s discovery has a positive effect on people’s daily lives, for example, the global positioning system (GPS). Third, Einstein’s theory of special relativity is a scientific theory, which according to dictionary.com is “a coherent group of propositions formulated to…

Overall, the purpose of this lab is to find the ideal substance in which to fill the tires in a rover that will go into space ( Mars ). We tested the speed and total distance traveled for the control ball and the foam filled ball. For speed I thought the foam filled ball would go farther because it weighs more than the control ball, and for distance if the ball goes on the ramp, it will lose speed , and if it hits the speed bump then it will lose speed in total for both, reducing the total…

Crumple zones are structural features mainly used in automobiles such as cars and trucks. They are designed to absorb the energy from the impact during a traffic collision by controlled deformation. Normally located at the front part of the vehicle, in order to absorb the impact of a head-on collision, though they may be found on other parts of vehicles as well. Crumple zones, are secondary safety features, this is due to the fact that secondary safety features only come into play once you have…

For task one My hypothesis was "If the forces on each side of the rope are equal, then the sum of forces will be zero. If we can determine the force each person on both sides of the rope, then we can determine if the sum of their forces will equal zero. " which was, correct. I know my hypothesis was correct because of the balanced force. A balanced force is when you have an equal amount of force on each side of an object when force is being exerted on it, it doesn't move because there is no…

Learning Experience number ( 2 ) 1- Arnold Dumbbell Press - raising the dumbbells as i rotate the palms of my hands , is the concentric motion. The second phase, as I lower the dumbbells back down, is the eccentric motion, . as i pause while the the dumbbels are at the top, is the isometric contraction. 2- Alternate Hammer Curl - as I curl the weight toward my shoulders, is the concentric motion. as I lower the weight back down, is the eccentric,motion. As the weight is held at the top of the…

The purpose of the experiment was to determine how altering the amount of mass in a makeshift rocket will affect its distance. Our hypothesis stated that when more mass is added to the rocket, its distance will also increase. To investigate this theory, we conducted an experiment in which the mass of the rocket would be changed using differentiating amounts of water. To measure the height of the bottle rocket, we took rope and attached it to the girth of the liter bottle to determine how high…
