Introduction

To have energy pertains to have the ability to force an object to move, energy can be stored in different forms such as, kinetic or potential. One type of potential energy is, gravitational potential energy, the energy stored in an object resulting from it’s height. Therefore, the higher an object is placed, the more gravitational potential energy it has. Simple machines, including pulleys and ramps, decrease the force, but apply the same amount of work each time and increases the distance traveled. P.E.=mgh W= F(X) In these sets of experiments we used two equations to calculate the potential energy and work. Potential

In the second experiment, we tried to figure out how much work is needed for a cart to go along a ramp when we changed the angle of the ramp. By first measuring how much force is needed when the cart is traveling vertically upward then measuring how much force is needed when the cart is traveling at different ramp angles. We then analyzed our data for the first experiment by comparing our predicted egg forces with the 25 N force at which the eggs will break. For the second experiment, we compared the Distance we pulled the cart (m) and Force needed to lift/pull cart (N) onto a scatter plot graph, in this we found that most of our work values were similar to each

One group member stood on a chair holding the egg out a certain height while others held the corners of the bed sheet to catch the egg. To get the initial height of the egg we used a meter stick to measure the height from the egg to the top of the sheet, with at least 3 significant digits. After we dropped the egg, we measured the distance the eggs pushed the sheet downward by using a meter stick to at least 2 significant digits. We repeated these steps above for every group. We then calculated the egg’s gravitational potential energy in joules by substituting our mass, gravity, and height values into the equation, Pe=mgh. To calculate the force the egg needed to use to push the sheet in Newtons, we used the formula W=F(X) by substituting our potential energy (w) and push distance (x). We compared our data of the eggs’ forces to the predicted value at which the egg will
