Project 1 Essay

What are the apparent and absolute magnitudes of the Sun? What does it mean that they are not the same?

6.2) If the mass of Body 2 was increased, then other bodies would be attracted to it and would change their orbits to come closer to Body 2. This would also affect the central star’s orbit because it is attracted to another mass of relatively large size. This occurs because there is a stronger gravitational pull because the object is now more massive and F_g= (Gm_1 m_2)/r^2

14) A car traveling 60 km/h accelerates at the rate of 2.0 m/s2. How much time is required for the car to reach a speed of 90 km/h?

3. Explain whether, during a trip, a car’s instantaneous speed (movement of an object at a specific instant) can ever be greater than its average speed.

Gravity: Gravity is a force of nature that keeps things on Earth instead of floating out of the atmosphere.

Mass (kg) x Gravity x Height. To determine the kinetic energy the team had to determine the distance

Would your mass change if you traveled from planet to planet? Why? No because mass doesn’t change from planet to planet it stays the same no matter where you are.

B: An object's angular momentum cannot change unless it transfer its energy it transfers that angular momentum onto another object. Because the angular momentum depends on the product of mass, velocity and radius, a spinning object must spin faster as it

Recently we have discovered an oddly shaped object that orbits the sun. For all intents and purposes it shall be called “Object X” or “X” for short. We have observed it passing through an asteroid field ten times. It has a moon that orbits 19,570 kilometers from

A comet in the Kuiper Belt would be affected by the presence of the planets in the solar system, not only the Sun. While the Sun has a huge mass, it is more massive than any of the planets in the solar system, it is far enough away from objects within the Kuiper Belt that its affect is comparable to the planets which lay closer. Since all planets within the solar system have significant gravitational fields (particularly the gas planets), its affect on a comet orbiting the Sun may change the shape of the comet's orbit into elliptical or other shaped paths.

This law can be best observed in space, far from the gravity of a star or planet, where there is no friction or air resistance. If, in the middle of deep space, you give a rock a little push, it will continue with the direction and velocity you gave it forever. The only way to stop it is to apply a force in the opposite direction. This law is not intuitive because we are surrounded

Gravity is the force of attraction that holds everything in its place, like the planets in orbit around the sun.

Gravity from many larger objects are the cause for the formation of the asteroid belt and the Oort

Gravity and its theory, is relatively new. Scientists still discover new correlations that they attribute to Gravity. Greek philosophers attributed the “natural motion” of the planets and stars as a part of the gods’ realm. They did not realize that gravity was involved until astronomers like Galileo and Brahe in the 1500s, discovered that the Earth and other planets revolved around the sun. Kepler later showed that they moved in an elliptical orbit, not in a circular pattern, which brought speculation as to why it occurred that way.

As Earth becomes more technologically innovated and crowded, space has become the answer of many of our problems. Over the past couple of decades, we have launched numerous contraptions into space such as satellites in which many currently orbit the Earth. These contraptions can be used for reconnaissance, communications, weather, search and rescue, navigation, exploration, television, and much more. Not a day passes by where we do not make use of these contraptions in our lives. However, as we progress towards the future, more and more of these satellites will be launched into orbit and as the fate of technology, they are bound to fail at some point and often get abandoned.
