Before proceeding, be sure you understand the distinctions among force, work, energy, and power. Force exerted on an object over a distance does work. Work can increase energy, and energy can do work. Power is the rate at which work is done.
Work. refers to an activity involving a force and movement in the directon of the force. A force of 20 newtons pushing an object 5 meters in the direction of the force does 100 joules of work. Energy. is the capacity for doing work. You must have energy to accomplish work - it is like the "currency" for performing work.
An object that is lifted from the ground gains energy because it can go on to do something else. A glass on the floor stays stable, one on a table can drop and smash, changing gravitational...
Work, Energy, and Power. Lesson 1 - Basic Terminology and Concepts. Definition and Mathematics of Work. Calculating the Amount of Work Done by Forces. Potential Energy. Kinetic Energy. Mechanical Energy. Power. Lesson 2 - The Work-Energy Relationship.
Power is the rate at which work is done on a system or the rate of energy transfer between systems. Rate refers to the amount of change in some measure of time. 1 Watt = 1 Joule/Second
Work is the measure of energy transfer when a force (F) moves an object through a distance (d). So when work is done, energy. has been transferred from one energy store to another, and...
