Motion of Freely Falling Objects Objectives: * To study the motion of free falling objects * To determine the acceleration due to gravity, g. * To derive quantities from the slope and intercept of graphs * To determine if the motion of a falling object changes by varying its mass Theory: The free fall is a known example or the most common example of a uniformly accelerated movement, with an acceleration a = -9.8m/s2 (vertical axis pointing vertically upward). If you choose

geometric mean is different from the arithmetic mean, we need to use the formula: g=arithmetic mean of return- (1/2)*variance, the variance is the simple historical variance, which is 1/(n-1)∑[r(s)-r ̅ ]^2. The standard deviation is the square root of the variance. The variance and standard deviation are measure the risk. We can see the risk of Union Pacific is greater than the ConAgra. That’s the high return, high risk. Besides, the historical beta of each company is come from the coefficient of

Characterizing Financial Risk – Historic Simulation and Modeling One Asset, One Time Period Imagine purchasing an asset today for $50 that you will sell tomorrow. You purchase the asset because you believe it will increase in value tomorrow (lets say you expect it to increase in value by 2%), but you also know its value tomorrow is uncertain—it may go up by more than 2% or it may actually lose value. Because you realize this, you decided you want to understand what risk you are taking by
