Potential energy stored energy - PowerPoint PPT Presentation
Cellular Metabolism
Cellular Metabolism. Chapter 4. Cellular Metabolism. Cellular metabolism refers to all of the chemical processes that occur inside living cells. Energy. Energy can exist in two states: Kinetic energy – energy of motion. Potential energy – stored energy.

Lecture 3 : How Matter is Organized
Lecture 3 : How Matter is Organized. Chemistry is the science of the structure and interactions of matter. all living things consist of matter. Matter is anything that occupies space. mass is the amount of matter in any object. weight is the force of gravity acting on matter.

Work, Energy & Power
Work, Energy & Power. Quick Review. We've discussed FORCES Magnitude – How hard is the “push” Direction – Which way does it act upon the object Applying a FORCE causes an object to accelerate (F=ma). m. F. F = m x a. (Units) lbs = lb-sec 2 /ft x ft/sec 2.

EQUILIBRIUM
EQUILIBRIUM. REACTION RATES + ENERGY. Chemical energy of a substance = potential + kinetic energy. Kinetic energy = doing energy (mechanical) Potential energy = stored energy. What these energies result from. Attractions between electrons and protons Repulsion between nuclei

4.2 Energy is transferred when work is done.
4.2 Energy is transferred when work is done. Tami Torres 2011. Some Helpful Definitions. Work ~ the use of force to move an object some distance. Joule ( jool ) ~ the standard unit of measure for work. One joule of work is done when a force of one Newton moves an object one meter.

Section One Energy
Section One Energy Energy : is the capacity to do some kind of work, such as moving an object. Examples: No matter how energy is defined, it is always involved when there is a change in matter. (Kinetic Energy: energy of motion) (Potential Energy: stored energy)

Thermal Physics
Thermal Physics. What is the difference?. Temperature . . . Is that all? State . . . Solid, liquid or gas Movement of the molecules. What makes a hot body hot?. All matter is made up of tiny particles that are always in motion the kinetic-molecular theory.

TOPIC 5: Work, Energy & Power
TOPIC 5: Work, Energy & Power. WORK. Definition of Work: When a force causes a displacement of an object Components of the force need to be in the direction of the displacement. Net Work done by a Constant Net Force. Work = Force (F) x Displacement (x) W = Fx W = Fx = (Fcos θ)x
