Steroid Lab Report

In the movie when the crew was on the crater drilling, nothing was coming out of the hole. When there is drilling taking place the rock or dirt needs to be displaced into the surrounding area. In the movie nothing came out of the hole during the entire drilling process. There was almost no gravity on the asteroid to be able to hold the remnants and dust in the hole being drilled.

Conclusion: The results of this lab were found through seemingly simple equations, basing all of your work off of data such as time and distance can become frustrating due to human inaccuracy, but the results show the height and initial velocity of the marble. The results are all reasonable compared with the beginning values that we collected during the lab, and even without calculations fit into the equation. The concept of projectile motion was the basis of this lab, focusing on using kinematic variables and equations to find the

Purpose: Weighing objects. Figuring out the density with an object by calculated volume and Archimedes’ Principle.

Gerta Keller, professor of geosciences at Princeton University, has recently conducted research on the Chicxulub asteroid in which she analyzed new core samples taken from the asteroid site (Botzer 2004). These samples indicate that the impact that occurred at Chicxulub actually predated the mass extinction of the dinosaurs, which occurred at the Cretaceous-Tertiary boundary about sixty-five million years ago. Keller claims that the Chicxulub impact occurred approximately 300,000 years before the extinction (Keller 2004). Although previous researchers estimated that the Chicxulub asteroid was the cause of the extinctions, there had always been doubts about the exact age and size of the crater, and about the origin of the “mega tsunami deposits” that were located within the crater (Keller 2004). The focus of Keller’s recent research was on finding some answers to these questions. To do so she analyzed Cretaceous limestone, dolomite, and anhydrite deposits as the site of the Chicxulub crater (Keller 2004).

Section Heading: The reason I think the golf ball will go the farthest is because it has the most density and density means “to have the degree of compactness of a substance.”I believe the tennis ball will go the second farthest because it has almost little density and it has no core at all and it's hollow.When the ball is hit with the most density it will give it the weight and power to travel great distance but unless the ball has to much weight it won’t go far.The baseball has the least greatest density so I gathered information

Massive boulders rained from the sky; each breaking as it struck the ground. Debris scattered and

To determine whether the height at which a marble is dropped affect the size of the crater.

Introduction: Accuracy and precision were the major aspects of the lab. Accuracy is how close the average of the measured values are to the actual value. Precision is the closeness of repeated measurements. In the lab, the aim was to get as close as possible with both accuracy and precision when determining the mass and volume of the spheres. The mass was determined by weighing the spheres on the Analytical Scale and Triple Beam Balance Scale. The volume is determined by measuring with a ruler and by water displacement. The standard

Aim: The aim of this experiment is to see which ball is better quality for bouncing and what is a lot more reasonable for price and size.

Hypothesis: No the size of the crater and ejecta will change because it will have lighter and harder impacts on the surface.

The “giant-impact hypothesis” explains the creating of the moon by a collision of the Earth by a large size rock named Theia. In the past, scientist explained that the rock Theia collided at an angle towards earth and vaporized Theia completely and part of Earth. The debris then came back on Earth and some debris orbited Earth creating the moon. Samples of rock from the Moon are identical from Earth that gives evidence to this theory. Over the past 15 years, more evidence suggested that the rock Theia made a high-energy impact that decimated both Theia and most of Earth, the dense vaper than formed an atmosphere that filled a space than 500 times bigger that today’s Earth. Some debris than collided back to Earth and some formed the Moon. Scientist

Notice that the velocity after the collision is significantly lower than the velocity prior. This is because the the objects stick together, essentially forming one object now that moves with a uniform velocity. As mentioned earlier, inelastic collisions do not conserve kinetic energy. Using the equation for kinetic energy, K.E.=1/2mv2, we calculated the kinetic energy prior to the collision to be 13300 g*cm2/sec2 for the short range setting, and 34400g*cm2/sec2 for the medium range setting. The method of calculating the kinetic energy after a collision has a slight variation.

How exactly the asteroid damaged the Earth remains unclear, but the power released by such an impact is unquestionable. Effects possibly include reduced sunlight over a period of several months which possibly led to the decline or even total halt of primary production (via photosynthesis). One of the dominant signatures of the extinction at the KT boundary was the low activity of primary production, the possibility of reduced sunlight is high (Schulte et al. 2010) . Even if the primary production proved to be on a decline when this impact occurred, there is still some uncertainties as to where exactly the impact hit. This was why asymmetries in subsurface features of the Chicxulub crater were observed via geophysical methods were analyzed and it was calculated from estimates that the
