Determining g on an Incline
Lab #1
Theory: During the early part of the seventeenth century, Galileo experimentally examined the concept of acceleration. One of his goals was to measure the acceleration due to gravity, or the acceleration of freely falling objects. Unfortunately, his timing devices were not precise enough to measure the free fall time directly. He decided to “dilute” gravity by using fluids, inclined planes, and pendulums.
Galileo’s idea of diluting gravity using inclined planes worked like this: the acceleration of a rolling cart on an inclined plane is small, therefore is easy to measure; when the angle of the incline gets bigger, the acceleration will get bigger; by measuring the dependence of the acceleration on*…show more content…*

Using Vernier, we clicked collect while releasing the cart after motion detector starts to click. This was done moving the hand quickly out the path. Using logger pro, indicated which portion was to be used by dragging across the graph to indicate the starting and ending times. Then the linear button was clicked to perform the linear regression of the selected data. The Linear Button was used to determine the slope of the velocity vs. time graph, only using the portion of the data for times when the cart was freely rolling. We found the acceleration of the cart from the fitted line. Record the value in the data table. These steps where repeated 5 mores times. Measured the length of the incline, x which is the distance between the two points of the ramp. Measure the height, h, the height of the book(s). The last two measurements was used determine the angle of the incline. Raise the incline by placing a second book under the end. Adjust the book so that distance, x, is the same as the previous reading. Repeated these steps with 3, 4 and 5 books.
ANALYSIS DATA
The greater the incline and greater the height, the greater the acceleration of the cart. -This experiment measured the acceleration of a cart moving down a sloped track in order to find a relation between the acceleration of an object and the sine of the angle at which it is moving. There were three separate experimental stages, with the variable being the angle at which the

The derived formula was v=√(μs*r*g) By substituting the numerical values in the equation, the maximum safe cornering speeds were calculated in following table: *Note: μs=0.9 is dry condition, μs=0.7 is wet condition Scenario 2 In this scenario, a vehicle is turning right downwards an incline. In this case, the x component, of the normal force is greater than centripetal force and the vehicle is wanting to slide down the incline, towards the center of the curve. However, friction

## Acceleration Due to Gravity

2131 Words | 9 PagesAcceleration Due to Gravity Introduction In this lab you will measure the acceleration due to gravity near the earth’s surface with two experiments: first, by determining the time for a steel ball to fall a known vertical distance (free fall), and then second, by measuring the velocity of a cart at various points as it glides down a slightly inclined and nearly frictionless air track (slow fall). Equipment Part 1: Free-Fall • Free-fall apparatus (steel plate, drop mechanism) • Electronic Timer •

Cohabitation is extremely popular and has become quite the trend. When looking at both married and cohabitating couples there are advantages and disadvantages to both, but when one looks at the day to day small things they share some common ground.

It was hypothesized that the data collected would support the empirical, within reasonable percent error. By determining the graphical relationships between different variables and their effect on the period of the pendulum, the raw data revealed an equation.

The cart was given velocity by releasing a compressed spring within the cart onto a hard object (force sensor) and then letting it move and up and down the incline plane. Logger Pro recorded the carts velocity and displacement while the cart was in motion as well as the force felt on the sensor at the bottom of the plane during this time period. Whether or not energy was conserved was determined by calculating the energy of the cart at different points on the incline plane and

Calorimetry is the process of determining the changes in energy of a system by measuring how much heat is exchanged with the surroundings (physicsclassroom.com, Calorimeters and Calorimetry, 2015). A calorimeter is used to determine this change in heat and by using the energy equation Q=mc∆T, where c is the constant specific heating capacity of water of 4.18J/g/°C and m is the mass of water, the energy used can be found.
