# Oscillation Of The Pendulum

Improved Essays
OBJECTIVE:
The pump is made of pendulum, two-leg lever and cylinder with the piston which pumps the water. Oscillation of the pendulum is maintained by periodical action of the human arm. Oscillation period of the pendulum is twice bigger than the period of the lever oscillation. Piston of the pump has reverse effect on the lever and damps its oscillation. Damping of the lever motion causes damping of the pendulum, but the work of the force damping the pendulum is less than the work of the forces which damp the lever. Equilibrium position of the lever is horizontal, and the equilibrium position of the pendulum is vertical. Oscillation of the lever and the pendulum take place in the same plane, vertical in reference to the ground. Physical model
The lever oscillates forcedly, not freely but in a condition of damping its movement. One can assume that the total mass of the lever is in the point where the user system reacts. This equivalent material point of the lever has a variable kinetic energy in reference to the ground. But the lever is periodically changing the direction of the rotation around its axis. This periodical change of the direction is fully depending on the oscillations of the pendulum, so the lever does not have its own oscillation …show more content…
This loss is the consequence of the work of the forces damping the oscillations of the pendulum. Total loss of the oscillation energy of the pendulum depends on the work of radial damping force of the pendulum AP, and the work of orbital damping forces of the pendulum AFP, which results from friction on the pendulum axis and the resistance of air:

EO = AP + AFP (6)

EFFECT OF FREE ENERGY OF THE PENDULUM-LEVER OSCILLATING SYSTEM:

Where only the lever is loaded by reverse action of the user system, is based on two key properties of this oscillation system. First is related to the fact that the lever does not have its own oscillation energy, and the second to the fact that the work of the orbital damping force of the lever is greater than the work of the radial damping force of the

As height is lost potential energy is built up and as height is gained kinetic energy is built up. The transformation of kinetic and potential energy is referred to as mechanical energy transformation. Both Kinetic and Potential energy are greatly affected by gravity. These energies alone cannot pull the roller coaster; it requires gravitational potential and kinetic energy in order to maneuver the cars as intended. The speed corresponds with kinetic energy where as the height corresponds with potential energy. Although speed and the transfer of energy are main sources of acceleration another force involved in the acceleration of the roller coaster is gravity. (Normani,…

First, we started out with a ramp that we dropped the ball on. That was our potential energy. Next, we had a ball drop down a tub at approximately 180°. That was mechanical energy. After that, the ball went through an elbow and hit another ball causing more mechanical energy and thermal energy from a ball hitting the other ball. This step is where we needed speed. As soon as the ball gets hit, it drops down a tube. Which is more mechanical energy. Next, the ball flies into an…

Also, in my assumption, the energy loss of gravitational potential energy includes both energy loss due to inelastic collision and energy loss due to friction at the pivot. In order to find the energy loss due to non-elastic collision only, the swing of golf club without a golf ball is analyzed. If there is no ball, the friction at the pivot will be only the consideration of energy loss.…

This, however, is not an actual spring, as the gap would provide an apparent opening in the animal’s exoskeleton. Instead, this mechanism is a saddle-shaped device called a hyperbolic paraboloid (Patek, 2004). This shape allows a reduction of stress by allocating the potential energy over a three-dimensional surface. This is dissimilar to a spring because the latter only compresses in one direction whereas the hyperbolic paraboloid can bend both upwards and downwards while compacting itself (Patek, 2004). Immediately after the paraboloid rapidly extends, the mantis shrimp instinctively draws it back into a spring-and-catch system that stores the potential energy with little leakage until the next release (Summers, 2004). With this system speeds up to 23 meters per second (51.4 mph) can be achieved from an organism approximately 30 centimeters in size (Patek, 2004). With this remarkable speed, great amounts of friction are generated. This leads to a nearly instantaneous vaporization of the surrounding water, which appears as if the liquid has been displaced. This is called a cavitation bubble, and can be up to a quarter inch in size (Patek, 2004). These vapor bubbles are then released in the form of light, heat, and/or sound. The achievement of a cavitation bubble can only be produced by organisms that can strike nearly as fast, or faster than, the mantis shrimp (Patek,…

When the spring is not stretched and the weight on the string is the highest it can be from the ground the gravitational potential energy is at its maximum amount and the spring potential energy is at a minimum since it is not stretched. Kinetic at this point is at zero. Next, as the weight starts to drop the gravitational potential energy begins to decrease while the spring’s potential energy increases as it begins to stretch. During the middle the kinetic energy is at its maximum since the kinetic energy is the energy of motion. Lastly, as the weight nears the ground, the gravitational potential energy is at its minimum since the weight is as close as possible to the ground, the springs potential energy reaches its maximum since the spring is as stretched as it will go with the specific weight attached and the kinetic energy returns to zero. This change from maximum and minimums describes the oscillations of GPE, SPE and KE as shown in figure blah blah. Furthermore, as GPE increases the energy comes from KE because the object is nearing a stop which means energy is transferred to potential energy, but since the spring is not stretched when GPE is at a maximum the kinetic energy is transferred to GPE. This also explains why the variations in…

Mechanical energy in the total amount of energy present in a mechanical system. Whether it is moving, kinetic energy, or stored, potential energy. This essentially means that an object has mechanical energy if it is distanced from a position of zero potential energy or if it is in motion. A vehicle in gear for example contains kinetic energy because it is moving, this is mechanical energy. Another example is a textbook being lifted off a desk; it is above the point of zero potential energy therefore it has potential energy. When an object is in motion in any direction, it can be described as kinetic energy. Kinetic energy can be vibrational, translational, rotational or one of several different forms. When an object is storing energy based on its relative position in a force field such as gravity, it is described as potential energy, a term that was first used in the early nineteenth century. Energy is most often measured by the product of Newton’s and meters which are also known as Joules. Mechanical energy is extremely diverse due to its many different aspects. It is so diverse that it exists in every single body in the universe. Mechanical energy is everywhere; from a football being tossed to a pencil falling off of a desk. Discovering examples of mechanical energy is extremely easy because of this. There have been many developments recently regarding the harnessing of…

The purpose of this experiment was to observe how the law of conservation of energy applies to a roller coaster system. In doing this we were able to determine the velocity of the cart as a function of its height upon the roller coaster, find the kinetic and potential energy for each trial of the cart and conclude energy loss due to friction. The results from part one concluded that as the roller coaster cart went down a hill the potential energy was converted into kinetic energy that resulted in an increase of speed. When the cart was at its highest peak it had the lowest velocity, but at its lowest point it in turn had the highest velocity. The results from part one also showed that the value for g varies only slightly for different masses.…
