Gravitational potential energy

WORK and ENERGY Work done by a constant force 1- The drawing shows a plane diving toward the ground and then climbing back upward. During each of these motions, the lift force acts perpendicular to the displacement , which has the same magnitude, 1.7 × 103 m, in each case. The engines of the plane exert a thrust , which points in the direction of the displacement and has the same magnitude during the dive and the climb. The weight of the plane has a magnitude of 5.9 × 104 N. In both motions

Introduction Potential energy is energy stored in an object that gives it the capacity to do work or make things happen. Every object positioned above the ground had gravitational potential energy (Gravitational Potential Energy = mass x gravity x height), therefore when a ball (which has gravitational potential energy) is dropped, gravity pulls the ball towards the earth’s surface. The potential energy of the ball transforms into kinetic energy, or the energy of a moving object, as it falls (Kinetic

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

of potential energy to kinetic energy using a model roller coaster track? II. Background Research Did you ever wonder how a roller coaster works? Why does one roller coaster go faster than another at certain points on the ride? This paper will discuss how potential energy turns into kinetic energy at different points along the track of a roller coaster. The important terms that will be discussed are potential energy (stored energy), kinetic energy (energy of motion), gravitational potential energy

analyze the gravitational potential energy and kinetic energy of a pendulum. They will be able to understand that a pendulum can have both kinetic energy and gravitational potential energy as it moves from one extreme to the other. Student Friendly Learning Objectives (Posted on the white board) Knowledge: I can measure and analyze the gravitational potential energy and kinetic energy of a pendulum. I can understand that pendulums can have both kinetic energy and gravitational potential energy as their

The mechanical, gravitational potential and kinetic energies (measured and average) showed trends with the masses of the balls. The big ball (larger mass) possessed more mechanical, gravitational potential and kinetic energy than the small ball (see summary table above) whereas the ball with the smaller mass possessed less energy correspondingly (3.9976 > 0.4588, 1.2242 > 0.0428, 6.1853 > 1.2242). This trend was consistent throughout all of the recorded results. This can be justified by the equations

thoughts while swinging: what is the kinetic and potential energy it requires to swing; will my 3 year old niece swing faster than me, since she weighs less; and lastly is it possible to swing above the support bar of the swing. According to Hyperphysics, the definition of kinetic of energy is: “energy of motion” (“Kinetic Energy”, 2013). The kinetic energy of an object is the energy it possesses because of its motion. The formula that represents kinetic energy equation

The equation for gravitational potential energy near Earth’s surface is U = m*g*h (Walker 395). In this equation, m is the mass of the object in question, which in this case would be the climber. The value g corresponds to the value for gravitational acceleration, which for Earth is 9.81 m/s2, and h is the height of the climber relative to the ground. It is important to note that for

Justification and Relevance of Lesson Energy is the ability to do work. It has the potential to make changes, and any changes are due to work being done. This is significant because work can generate energy, and energy itself can do work (i.e., work done on windmills by the wind produces energy, and energy is used in homes to do work).

Conservation 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 bottom
