Energy is the ability to do work. Doing work is transferring or transforming energy. Work is exerting a force through a distance to change the motion, and thus the energy, of an object.Click to see full answer. Considering this, what is a force acting over a distance?Work Done by a Constant Force. When a force acts on an object over a distance, it is said to have done work on the object. Physically, the work done on an object is the change in kinetic energy that that object experiences. The SI unit of work is the newton-meter or joule (J).Also, what is meant by work done by a force? Work done is defined as product of the force and the distance over which the force is applied. Work is done when a force is applied to an object and the object is moved through a distance. For example, when you lift a load you are applying a force over a distance so you are doing work. Similarly, what is the energy used when a force is exerted over a distance? Units of Energy Some Common Energy Units joule (J) The amount of work or energy exerted when a force of one newton causes a displacement of one meter calorie (cal) The energy needed to raise the temperature of 1 gram of water by 1 oC 1 cal = 4.184 J What is work done by a constant force?Work Done by a Constant Force. The work done by a constant force in moving an object is equal to the product of the magnitudes of the displacement and the component of the force parallel to the displacement. Work is a scalar quantity.
