The Relationship Between Kinetic and Potential Energy - Physics - Ashley Nestler
Because the hammer has mechanical energy (in the form of kinetic energy), it is able to do The total amount of mechanical energy is merely the sum of the potential energy and This is the subject of Lesson 2 - the work-energy relationship. When an object is moving under the influence of some conservative force field ( like gravity) and there is no loss due to friction or air drag/ fluid. Potential energy can transfer into other forms of energy like kinetic energy. total energy in a system is broken up into different types of energy at different . -GPE: Describe the relationship between an object's mass and its.
Power In a previous part of Lesson 1it was said that work is done upon an object whenever a force acts upon it to cause it to be displaced. Work involves a force acting upon an object to cause a displacement. In all instances in which work is done, there is an object that supplies the force in order to do the work.
If a World Civilization book is lifted to the top shelf of a student locker, then the student supplies the force to do the work on the book. If a plow is displaced across a field, then some form of farm equipment usually a tractor or a horse supplies the force to do the work on the plow. If a pitcher winds up and accelerates a baseball towards home plate, then the pitcher supplies the force to do the work on the baseball.
If a roller coaster car is displaced from ground level to the top of the first drop of a roller coaster ride, then a chain driven by a motor supplies the force to do the work on the car. If a barbell is displaced from ground level to a height above a weightlifter's head, then the weightlifter is supplying a force to do work on the barbell. In all instances, an object that possesses some form of energy supplies the force to do the work. In the process of doing work, the object that is doing the work exchanges energy with the object upon which the work is done.
When the work is done upon the object, that object gains energy. The energy acquired by the objects upon which work is done is known as mechanical energy.
Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy energy of motion or potential energy stored energy of position. A moving car possesses mechanical energy due to its motion kinetic energy.
A moving baseball possesses mechanical energy due to both its high speed kinetic energy and its vertical position above the ground gravitational potential energy. A World Civilization book at rest on the top shelf of a locker possesses mechanical energy due to its vertical position above the ground gravitational potential energy.
A barbell lifted high above a weightlifter's head possesses mechanical energy due to its vertical position above the ground gravitational potential energy. A drawn bow possesses mechanical energy due to its stretched position elastic potential energy. Mechanical Energy as the Ability to Do Work An object that possesses mechanical energy is able to do work.
In fact, mechanical energy is often defined as the ability to do work. Any object that possesses mechanical energy - whether it is in the form of potential energy or kinetic energy - is able to do work. That is, its mechanical energy enables that object to apply a force to another object in order to cause it to be displaced.
Numerous examples can be given of how an object with mechanical energy can harness that energy in order to apply a force to cause another object to be displaced. A classic example involves the massive wrecking ball of a demolition machine.
The wrecking ball is a massive object that is swung backwards to a high position and allowed to swing forward into building structure or other object in order to demolish it.
Upon hitting the structure, the wrecking ball applies a force to it in order to cause the wall of the structure to be displaced. The diagram below depicts the process by which the mechanical energy of a wrecking ball can be used to do work. Does this match the Law of Conservation of Energy?
Look back at the formulas and keywords. Explain what is missing and how it relates to the Law of Conservation of Energy. Now find the total energy TE in the system at each point and add it to the data tables also. Use the empty rows to add the new data.
