Physics Of Motion And Energy - 1504 Words

Aim Using Physics principles such as equations of motion and energy illustrate how the landing place of a ball bearing swung into a razor blade can be calculated and a target can be placed, predicting this landing spot. Hypothesis Through using Physical Sciences principles I ill be able to place a target in the approximate location of where a ball bearing will land. Introduction Motion and Energy are both related and understanding of both are important in the completion of this experiment. There are four main equations of motion, Vav = s/t, v = u + at, v2 = u2 + 2as s = ut +  ½at2. These four equations can be used to determine the information of an objects motion (Henderson n.d. a). There are different types of motion, specifically for†¦show more content†¦Mechanical energy is the energy which is based on either motion or position of an object (Simmons n.d.). Mechanical energy is divided into two types, potential energy (EP) and kinetic energy (EK). Potential energy is the energy of an object based upon its position relative to another. There are many types of potential energy such as elastic and gravitational potential energy. One the most common types of potential energy, which is discussed in this topic, is gravitational potential energy (given by Ep = mgh). Due to this, gravitational potential energy is equal to the work done to move an objec t (W = Fs). Kinetic energy is the energy of a moving object, (Given by EK =  ½mv2). Work done is the change in kinetic energy or the force times the displacement (W = Fs or W = ΔE). An important aspect of mechanical energy is known as the law of conservation of energy, which states that in a closed system that the total energy of that system will remain constant, as energy is not created or destroyed, rather it is changes from one form to another (Nave n.d.). In effects this means that in a system as a ball falls its gravitational potential energy is transferred to kinetic energy, until just before it hits the ground all the potential energy has transferred to kinetic energy. This is not a perfect system and energy will be lost in other forms such as heat, sound and light. But that will be negligible in this experiment. Method 1. Attach two
