Jessica Yan Rick St. Denis, Tyler Wiseman 13 September 2012 Projectile Motion: Ball in the Bin Purpose: The purpose of the experiment is to determine the velocity of a ball launched from the Projectile Launcher device, and then to use that velocity to find where on the floor the ball will land given a specific angle. Theory: Two-dimensional motion is as it sounds, made of the two components of Vertical velocity and Horizontal Velocity. Horizontal Motion can be described as constant, neglecting air resistance, and Vertical Motion is characterized by the acceleration of gravity pulling at 9.8m/s². In this particular experiment, the total velocity will be split into the two components in order to find the time in the air, and horizontal distance from the launcher. The motion of these components can be described as d=vt for constant horizontal motion, and d=1/2at² + Vit.
d. Their values get larger as the temperature is increased. e. An order equal to zero means there is no concentration dependence with rate. 2. The gas phase reaction A + B C has a reaction rate which is experimentally observed to follow the relationship rate = k[A]2[B]. The overall order of the reaction a. is first.

Once the wavelength is calculated, the heat capacity ratio for each of the gases will be calculated. Introduction When temperature is increased in a system, the internal energy is raised. It is assumed that the system has a constant volume, so the increase depends on different conditions based on which the heating takes place. If internal energy is plotted against temperature, a curve can be seen in a graph. The graph shows a variation as the system heats at a constant volume.
PHY/101 Week 3 Exercises Ch. 15: Exercise 2 Which is greater—an increase in temperature of 1 Celsius degree or an increase of 1 Fahrenheit degree? An increase in temperature of 1 Celsius degree Ch. 15: Exercise 4 Why wouldn’t you expect all the molecules in a gas to have the same speed? Gas molecules move in different directions and always colliding with each other which will always cause random speeds to accure.
Answer the following questions: 1. Compare Aristotle's concept of inertia with the ideas of Galileo and Newton. In making your comparison, state the concept as each interpreted it (in your own words) and give the similarities and differences. Aristotle believed that the laws governing the motion of the heavens were a different set of laws than those that governed motion on the earth. As we have seen, Galileo's concept of inertia was quite contrary to Aristotle's ideas of motion: in Galileo's dynamics the arrow (with very small frictional forces) continued to fly through the air because of the law of inertia, while a block of wood on a table stopped sliding once the applied force was removed because of frictional forces that Aristotle had failed to analyze correctly.
We wouldn't live nearly as long as we do without them. The same goes for the discoveries of the solar system. It is impossible to rand their importance, so they are listed in the order they were discovered. The first time humans have ever discovered a planet was in the 2nd millennium BC by the ancient Babylonian astronomers. Soon, Aristarchus of Samos, and later in Nicolas Copernicus' heliocentric system that he published in 1543, the Earth came to be considered a planet revolving with the other planets around the Sun.
But from here you may wonder what terminal velocity is? The answer is, terminal velocity is the velocity of an object when the sum of its drag force equals the downward force of weight that is acting on the object and hence meaning the object has no resulting acceleration and is moving at a constant velocity. However through research what I found is that you cannot 100% reach the terminal velocity of an object, but only x%(where x is any number between 0 and 100) of an objects terminal velocity as terminal velocity is asymptotic. Though this information is true, we still refer to an object that is falling with constant motion as reaching its terminal velocity and thus say that any object can and does reach terminal velocity. The way the viscosity of a liquid affects terminal velocity refers to the second statement that an object does reach terminal velocity.
The velocity can be obtained by finding the slope of the graph of position as a function of time. The acceleration can be obtained by finding the slope of the graph of velocity as a function of time. The critical concepts are contained in the equations for motion with constant acceleration in one dimension, as follows: x=x0+vxot+1/2axt2 Equation 1 vx=vx0+axt Equation 2 In these equations, x is the position at time t andx0 is the position at time t=0 of the object; vxis the velocity of the object along the direction of motion, x, at time t, and is the velocity of the object along the direction of motion, x, at time t=0 ; and ax is the acceleration of the object along the direction of motion, x. Uniformly accelerated linear motion is all around us. Architects often consider the safety of the slides by simulating and calculating the acceleration of a child slides down.
