How Energy Is Conserved As It Is Converted From One Form...

Abstract: The aim of this experiment to determine whether energy is conserved as it is converted from one form of energy to another using a cart which rolls up and down an incline plane. 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 comparing these different values. The initial energy of the cart before it was projected was calculated to be (0.144 + 0.02) J, when the energy was all elastic potential energy and the energy of the cart when the spring was at maximum compression during the first collision with the sensor was calculated to be (0.03+0.00294) J, when energ y was again all elastic potential energy. This shows that energy was not conserved during the motion of the cart up and down the incline plane, therefore work was done by frictional forces and the normal to the incline. The energy of the cart was lost to heat, sound, and mostly friction between the spring and the cart. Introduction: Energy is defined as the capacity of a physical system to preform work. Energy can exist in many forms including heat, kinetic, potential, and light. TheShow MoreRelatedPhysics Of The Field Of Medicine1381 Words   |  6 Pagesin the field of medicine.

The ball that travels down a ra mp with a steeper angle, will have a greater velocity therefore produce more momentum because it has a greater velocity compared to the ball travelling down a ramp not as steep. This will then affect the amount of kinetic energy a ball possess after collision. The ball that is travelling down the rampRead MoreThe Existence Of Life And Energy1492 Words   |  6 Pagesexistence of life and energy has always been questioned. It is not clear as to how life on earth is sustained by energy and how that energy is produced. The explanation to all of this lies in the law of conservation of energy and the amazing work done by many intelligent people. Over many centuries, the development of new technology has furthered studies in science and advanced the standard of life for many people. The steam engine is one example of this.

In most cases, any process that does not obey it never happens. However, there different processes that do not violet it but never occur in nature. First law of thermodynamics fails to answer some important questions. i. It is known that first law cannot indicate direction of heat transfer. Heat flows from hot body to a cold body and never the reverse. If the reverse process occurs energy would still be conserved, yet first law does not explain this phenomenonRead MoreScience in a Lacrosse Shot Essay1319 Words   |  6 Pagesentailing a kinetic linking from your feet to your arms.
