In work definition we use only displacement why we didn't use distance in work definition?

Some Physics definitions ignore the real world of Nature. Forces and distances are four dimensional including real and vector quantities. Work is defined as the scalar product of two vectors and ignores the scalar cross distances and vector cross products..
Gravity is a scalar force and gravitatinal potential energy is mgh where mg is a scalar force and h is a scalar distance. This is not called work because it is not the scalar product of two vectors.
Nature and Physics involves scalar and vector quantities, in other words Quaternion quantities. The Quaternion product of force and distance is:
(f + F)(d + D) = (fd - F.D) + (fD + dF + FxD).
Physics only defines work as F.D and ignores the other 'work' including Torque,FxD.

What is the Definition of displacement in scientific terms?
" The minimum distance between two points is known as Displacement.""The vector distance between two points is known as Displacement."Displacement is a vector quantity and is shown by d.Displacment is the distance and direction of an object's change in possition from the starting point. ( i got this from my science text book but im only 13 so DONT JUDGE ME!!! thank you. ^.^)
What is the word for the definition how far an object has moved?
"Distance" describes how far something has moved. "Displacement" describes not only how far, but also in what direction.
What is the unit for displacement?
Displacement is measured in distance, so any measurement dealing with only distance will work. The SI units are meters.
How are displacement and distance similar?
Distance and displacement are similar because both have magnitude.However, displacement is a vector quantity since it has both magnitude and direction whereas distance is a scalar quantity since it has only magnitude.
What is displacement in physical?
Displacement is a vector quantity. This means it has both size AND direction. Therefore, displacement is defined as distance in a given direction. Rather then simply 'distance'. Distance itself is a scalar quantity... and only has size. No direction. 20m - Distance. 20m upwards - Displacement.
What is the difference between the distance vs displacement?
Shortest distance is called displacement . displacement =average velocity / average time . It is a vector quantity both has magnitude and direction.But,distance is a scalar quantity having only magnitude.
Does the displacement between two objects locate the objects?
No. Displacement refers only to distance; you also need the direction.
Explain how the displacement of an object could be zero while the distance traveled was 150 miles?
Displacement is only the distance from the starting point. As long as you return to where you started, then you can travel 1.0 x 10^999999999999 miles and still have a displacement of zero.
Is the magnitude of displacement greater than or equal to the magnitude of the distance traveled?
Displacement can be equal to distance traveled or less, depending on the shape of the route, but it can never be greater than the distance traveled.
How are distance and displacement different?
Displacement is a vector quantity because it is has both magnitude and direction, while distance is a scalar quantity because it has only magnitude without direction.
How do distance and displacemen and different?
Look distance is the total length covered by a body and displacement is the shortest length covered by a body. Also displacement is a vector quantity (has both magnitude and direction) and distance is a scalar quantity (has only magnitude and no direction)
Can displacement be more than distance?
No. Distance can be greater than displacement, but not less. The magnitude of the displacement between two points is also the minimum possible distance of a path between the same points.However, the displacement can be zero if the distance is not if the object's starting point and ending point are the same.
