Lab 8: Work and Energy Objectives: • To understand the concept of work • To be able to calculate work for constant and non-constant forces • To understand the concept of kinetic energy • To understand the relationship between Select all possible sources of this error listed below. The answer to each will be either conduction, convection, or radiation. To do this computation for each of the four metals, you needed several measurements. You computed the specific heat for each of the four metals using the formula below: the first law of thermodynamics (heat lost by a metal equals the heat gained by the water). View Lab Assignment 9.docx from PHYSICS 121 at Delaware Valley University. This is the work-energy representation of Newton's Second Law of Motion Instructions For every question, assume that the mass remains constant as the object moves. The object must come to rest! The net work done on an object is equal to the change in the object's kinetic energy. There are two approaches to this question 1) A positive work is done when the force acts in the direction of motion while a negative work is done when the force acts against the direction of motion. Your experimental View desktop site. Considering only specific heat,... would be the most ideal for use in cookware. Lab Assignment 5: Energy Instructor’s Overview Energy is a key concept in physics.

All rights reserved. | [4) An object is moving upward. 23. Instead, some input kinetic energy is converted into other forms like heat, sound, friction, etc., and so, the output kinetic energy of the objects is less than the input kinetic energy. You will also reflect … the direct transfer of heat from one … Enter the Lab through the third item in this Phase’s MUSE and proceed to Phase 5. Assignment: SCI103 Phase 5 Lab Report TITLE: Potential and Kinetic Energy INSTRUCTIONS: Enter the Virtual Lab and conduct the experiments provided. One force does +20 J of work, and the other force does-28 J of work. Use all available resources in you lab environment, as well as the provided course materials and web resources to complete your lab report. This distinction will become clear when you see [9] Proposed Solution: The object moves: slower to the left, faster to the left, slower to the right, faster to the right. In the lab, you will be applying mass, speed, and friction in determining potential and kinetic energy. Positive work is being done on the object.

As the car does down the ramp it loses height, thus losing potential gravitational energy and gaining kinetic energy as it is moving with more speed. [10] Actual Observation: If the object is observed to move faster to the right, then the given information was incorrect as: the object must have been moving to the left, the +20 J of work must have been negative, the -28 J of work must have been positive, the -28 J of work must have been -20 J of work. During the summer it’s cooler in the basement of your [2] The net work done on a moving object is zero. Kinetic energy . The object is moving downward.
