The results from the 3 Hubble diagrams vary in accuracy, this is measured by the R2 value which in other terms means the distribution of the data in relation to the fitted line of regression. The diagrams are also all measured by using apparent magnitude which is the measure of brightness as viewed from the earth and does not take into consideration distance which can mean results are not as accurate in comparison to absolute magnitude. Absolute magnitude is measured the magnitude of the star…

In conclusion, we can use Newton’s 3 laws of motion to maximize our rockets’ flight time. For Newton’s first law, our hypothesis stated the following: “We can apply Newton’s first law by minimizing the forces that resist motion. The way we will do this is to make the nose cone as smooth and pointy as possible. If the nose cone is too flat on the end, it will not cut through the air very well. The rocket must cut through the air swiftly, this means that resistance will be at its minimum during…

Physics has a lot of different concepts to it. Different types of theories and laws. If you really think about it everything has physics. Physics is the nature and knowledge that it encompasses. Everything that has physics, has math. Physics is the language of math. For example, posters tapped against a wall. There are all kinds of forces to that, forces like contact force, Gravity, and normal force. Gravity exist among all objects in the universe. Like in the wall and the posters tapped against…

The distance the rocket will travel will increase because the rocket has more mass. Newton’s 1st, 2nd, 3rd law and aerodynamic forces had an effect on the rocket. The changes made to the rocket was that more mass was added to the rocket. Two grams of clay was added to the nose cone. The straw is 205 cm body length and there’s 3 fins on the bottom that are 4cm x 2cm. Newton’s 1st law is if an object in rest it will stay in rest unless an outside force acts on the object. Also, if an…

In this experiment the main goal is to examine the correlation between position, velocity, time, and acceleration of objects, moving in one or two dimensions. Each and every experiment will be conducted under different conditions. For example, the first experiment requires a constant force (gravity) to act on the object, the picket fence. This experiments other condition is that we neglect friction. This object should be in nearly ideally circumstances. In the second experiment, the conditions…

For over 55 years, humans have been flying in space. With an understanding of evolution, it has always been assumed that human bodies have adapted to the gravitational force found here on Earth. The space station and the shuttle that most NASA astronauts will stay in orbits 350 km above Earth, with a gravitational pull 90% stronger than it is on the ground (NASA Space Bones). Giancoli describes objects orbiting the Earth as feeling weightless because they are, in essence, free falling towards…

Dark matter is matter that cannot be directly seen because it does not interact with light. This mysterious matter makes up the majority of mass in a galaxy. Although we cannot see dark matter we know that it is out there because we can see it effecting the motion of the stars in a galaxy and gravitational lensing. The first piece of evidence for dark matter is in the way we have observed galaxies moving. You would likely expect their behavior to replicate that of the Sun and the planets, with…

One concept that has interested is dark matter and dark energy. Dark matter is the thing that makes it possible for galaxies to exist. When astrophysicists and cosmologist calculated why the universe is structure the way it is, it became clear that there’s just not enough normal matter. The gravity of the visible matter is not strong enough to from galaxies and complex structures. The starts would more likely be scattered all over the place and not form galaxies. Therefore, cosmologist concluded…

Conservation of Mechanical Energy Anupama Cemballi Department of Physics, Case Western Reserve University Cleveland, OH 44106-7079 Abstract: Gravitation Potential Energy: Introduction and Theory: Gravitational potential energy is the potential energy an elevated object has due to the force of gravity. Potential energy is the stored energy an object has dependent upon its position. Near the surface of the Earth, the gravitational acceleration of an object is 9.8m/s^2. There is no uncertainty…
