Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.

In science, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled.
In physics, work represents a type of energy. Work is done when a force acts on something that undergoes a displacement from one position to another. Forces can vary as a function of position, and displacements can be along various paths between two points.
Examples of work include lifting a box against gravity (work done against gravity), pushing a car along a flat road (work done to overcome friction), and stretching a spring (work done to store elastic potential energy).
In physics, work is done on an object when energy is transferred to the object. In other words, work is done when a force acts on something that undergoes a displacement from one position to another. Forces can vary as a function of position, and displacements can be along various paths between two points.
Work is done when a force moves the object in the direction of the force and is given by the product of the force and the distance moved in the direction. , Where W= Work, F = Constant Force (N), d = Distance moved in the direction of the force (m) SI Unit for work is joules (J)
16 lut 2023 · In physics, work is defined as the change of energy in a system caused by a force applied over a displacement. When a force acting on an object causes the object to move, we say that work is done on the object.
