Energy to force. 11) Significance The resistance of the motor is quite small. If the force is constant, work may be computed by multiplying the length of the path by the component of the force acting along the path. Physicists define work as the amount of energy transferred by a force. Forces are the way that energy is transferred from one object to another when they interact, but forces are not the energy itself. An example of Work: A block displaced along a table by force (F) and distance (D). According to this theorem, when an object slows down, its final kinetic energy is less than its initial kinetic energy, the change in its kinetic energy is negative, and so is the net work done on it. When a net force acts on an object, then the object accelerates, it changes its velocity. Force is a push or a pull. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. 7.

The initial mechanical energy of a system equals the final mechanical energy for a system where no work is done by non-conservative forces (conservation of mechanical energy principle). If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy. 7m/s. Before delving into the specifics of energy to force conversion, let’s briefly review what energy and force entail. 67W (20. Therefore, the greater an object’s mass or the This relationship is generalized in the work-energy theorem. Roll a toy car over a rug and it'll quickly come to a standstill. What is kinetic energy? Kinetic energy is the energy an object has because of its motion. For example, kinetic energy is the energy of motion, and potential energy is energy due to an object's position or structure. This transfer of energy, depending on variables that alter states of motion, can cause injuries and damage cars and property. An object’s kinetic energy is directly related to its mass.
