Potential energy

concept to the process involving several constant forces and the process involving variable forces. After introduce the concept of kinetic energy, we will show the transformation between energy and work. Finally we will generalize these concepts to any system going through any process that involves energy and work and elucidate the fundamental concept of energy conservation. 5.1 Work The work that we are talking about is what a force produces during a process of moving an object. Two things must…

Paradox What is it? Have you ever heard the term “Straight as an arrow”? Well, this isn’t exactly accurate. Arrows don’t exactly fly straight, they twist and bend as they fly. When you draw back and release your bowstring the large force of kinetic energy stored in the limbs gets transferred into the arrow and this force causes the spine of the arrow to start bending as it gets pushed forward. The archer’s paradox is this bending of the arrow around the bow as it is being loosed before it…

elephant would have to jump onto the other side to get the little kid to his destination up in the tree. This shows that when the counterweight falls or is released the trebuchet pivots on its fulcrum, releasing the potential energy that was built up turning into enough kinetic energy to throw an object through the…

consisting of a piece of taut, a strong fiber extended over a steel frame using many springs, the fabric used on the trampoline bed has certain elasticity, the elasticity is generated by the springs connected to the frame, which store potential energy (the stored energy of position of an object). The first trampoline to be invented, was invented by a trapeze artist called Du Trampolin, he developed this idea to have a safety net and a landing device. But, have you ever wondered what is the…

Name: Institution: Course: Instructor: Date of Submission: Pendulum and spring Abstract In this lab, two systems namely a pendulum and a spring that exhibit simple harmonic motion were studied. The systems were subjected to a mass of known weight and allowed to oscillate. Afterwards, the period of each was determined. In addition, the harmonic properties in the systems and their limiting factors were determined through quantitative calculations. Introduction Any system that exhibits back and…

starting point of creating energy using water has been in progress for centuries from theory to experimentation, and in real life possible applications. It gave birth in modern time as Hydroelectricity a term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. In engineer’s eye’s it is a debatable energy source due to the fact that there id wind power, solar power, methane energy, etc. “Aside…

1. C Why: according to Newton’s first law of motion, an object that is free from all outside forces travels at a constant velocity, covering equal distances in equal times along a straight-line path, C is true. 2. D Why: not matter an object is still or is in motion, the object has inertia all the time. Inertia is a nature/property of any objects. 3. D Why: the ship is moving at a constant speed, which is in a balanced status. For the athlete, it would be likely to do a long jump on ground.…

Aim Simple Pendulum Experiment The aim of the experiment was to determine the effects of two factors (the length of a pendulum and the hanging mass of a pendulum) on the period of oscillation of the simple pendulum and to determine the value of g, the acceleration due to gravity. Apparatus Retort stand String Meter ruler Table Standard hex nuts (as suspended mass) Stopwatch Labelled Diagram Illustrating setup Method Experiment A: The simple pendulum was assembled using a retort stand,…

Long Jump Procedures: The participant has to stand behind the line and has to jump off of both feet and attempt to jump as far as possible while landing on both feet. The participant gets three chances to jump as far as they can, then they record their data. Advantages: This test does not take very long to do and it does not require a lot of equipment. Disadvantages: It takes some form to know how to do this properly so some participants may have an advantage over others. Validity: it is a good…

https://www.youtube.com/watch?v=NcmF5lDL8MM Have you ever been to an amusement park and wondered how a rollercoaster goes around the loop of the track? Well I sure have, this is all due to centripetal force. This is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving. The curves of these loops on rollercoasters resemble the curves of a circle. The coaster is continuously changing its direction while…
