1001 Lab 2 focal ratio & antiophthalmic factor; Acceleration * Introduction This overlay displays the kinship between the speed and acceleration, and there includes outstrip, time and pitch. We know hold /Time escaped=Velocity, Acceleration=?Velocity/?Time & Slope=?Y/?X, (Y is the distance from y-axis; X is the distance from x-axis). We stick out intake these equations to solve the problems and find the relationships between upper and acceleration. Moreover, this report shows the procedures of the experiment, to discuss and analyze the results of the experiment. * Procedures There are two contrary parts of this experiment, the first part is development a take track and a battery car to calculate the think speeding. To observe its motion, record the distance and time that car has passed with and sketch the graph of its motion. As for the second part is using the inclined track and cart, in this part, we use computer to reign graphs of distance vs. time and velocity vs. time for the cart on the incline, wherefore we can calculate and analyze the acceleration of its motion. We similarly make a prediction: if motion with a unalterable velocity and the motion with a constant acceleration.

* Results and Analysis For the first part, we use the equation Velocity= Distance/ Time escaped, to calculate the speed for many times, from the shape of the graph (Velocity vs. Time) that we can see the velocity is constant. Due to the equation: Slope=?Y/?X (Y is the distance from y-axis; X is the distance from x-axis), we can calculate the slope of this graph, and then we realize this slope is similar as velocity. From the graph of velocity vs. time, we find the acceleration=0, so there is no acceleration with the constant velocity. For the second part, I obtain the acceleration is the slope of the graph of Distance vs. Time, using the equation Acceleration=?Velocity/?time to obtain the acceleration of the cart moving kill the incline. Because the graph is a line not a... If you want to press a full essay, order it on our website: Orderessay
