The Relationship Between Gravitational Potential Energy,...

Purpose: To find out the relationship between gravitational potential energy, kinetic energy, and total mechanical energy of a cart as it rolls down a ramp Hypothesis: If the cart rolls down the ramp with constant speed, then the kinetic energy will get bigger, the gravitational potential energy will decrease, and the total mechanical energy will stay at the same constant value, because due to the law of Conservation of Energy, these are the estimated results. Materials/Apparatus: ramp (1) textbooks (3/4) meter stick (1) motion sensor (1) cart (1) GLX system Procedures: The ramp was raised at a 8.4 degree angle using 3 textbooks The length and the height of the ramp was measured using a meter stick The motion sensor was placed on the top of the ramp. The cart was placed near the notion sensor and released As the cart rolled down the ramp, the position-time graph of the cart was recored One point near the end of the graph was chosen and was represented by its d2 and the reference point, which was used to determine the height of the cart. (this point was kept throughout the whole experiment) The equation h = d (h/L) was used to calculate the height of the cart on the ramp The slope tool was used to determine the speed at any point The position and the speed was determined using the point near the start if the graph These values were used to complete the first row The other positions from the graph were used to complete the next three rows Observations:Show MoreRelatedConservation Of Energy : Sam Perelman1516 Words   |  7 PagesConservation of energy – Sam Perelman Purpose: To investigate the gravitational potential energy, kinetic energy, and mechanical energy of the cart as it goes down the ramp. Hypothesis If energy is conserved then the cart will have the highest gravitational potential energy at the top of the ramp and the highest kinetic energy at the bottom of the ramp but have a consistent total energy throughout its journey. This is because the equation for Eg is Eg =mgh so when h=0 E=0 (this occurs at the bottomRead MoreBroken steps4291 Words   |  18 Pageshas a potential energy of 6.0 J relative to the base of the incline.
