PPT-Kinetic Energy & Work

Pg 171 176 Kinetic Energy Recall A moving object has the ability to do work because it can apply a force to another object and displace it The energy possessed by moving objects is called kinetic energy . P. otential Energy. Energy and Work are closely related. Work. is a transfer of . Energy. SI unit for work is . Joules (J). Energy. is the capacity to do . Work. We recognize it by the . changes. it causes. Energy can change from one form to another without a net loss or gain. . Physics Standard SP3. Students will evaluate the forms and transformations of energy. . a. Analyze, evaluate, and apply the principle of conservation of energy and measure the components of work-energy theorem by . 4. th. form IGCSE. Chapter 17 in textbook (p. 142). Reminder: work and energy. In the back of your book:. Define what is meant by . work. . and . energy. List different . forms of energy. N.B.:. NOT fuels…. Homework Assignment Help.

Color. Brightness. Energy per photon changes. What is Energy?. Energy. is the ability to cause change.. . or….. The ability to do work.. Energy is measured in the same units (Joules) as work because energy transfers work.. Different Forms of Energy. You . need energy to force an object to move. You need energy to make matter change. . The . blowing wind, the warm Sun and a falling leaf are all examples of energy in use. .. . Energy makes motion and change possible.. Unit 4: Work, Power, and Energy I. Work When a force acts upon an object to cause a displacement of the object, it is said that work was done upon the object. There are three key ingredients to work: P3 Challenge– . A 62 kg crate is being pulled at constant speed across a floor by a cord that makes a 30.  incline to the horizontal. What is the coefficient of dynamic friction if the tension in the cord is 130 N? . How is work, power and energy related?. What is energy?. 2 types . Kinetic . Potential. 2. types . Gravitational . Elastic . Table of Contents . What are other forms of energy?. Mechanical. Thermal . I can define Kinetic and Potential energy.. I can identify Kinetic and Potential energy.. I can give examples of the two forms of energy.. I can explain how one can transfer to the other.. Work. The product of distance and the force in the direction an object moves.. Kinetic Energy. The kinetic energy of the center of mass of an object moving through a linear distance is called translational kinetic energy. . KE = ½ mv. 2. As an object rotates it experiences a type of kinetic energy known as rotational kinetic energy. Mechanical Energy. Kinetic Energy. Work-Energy Theorem. Gravitational Potential Energy. Energy is Conserved. Energy Conservation Application. Summary. Mechanical Energy. Mechanical Energy is composed of both:.
