A national curriculum comprising statements of attainment at different levels must be underpinned by some idea of "progression" in learning. Questions arise as to the nature and meaning of progression. To gain a deeper insight into how children progress in their understanding of science, this ...
The scientific meaning of the noun force also involves getting an object to move. In the mid-1600s, the great English physicist Isaac Newton figured out that the amount of force needed to move an object was directly related to both the mass of the object and how it is accelerated. (...

As emphasized by Xi, China will prioritize scientific and technological innovation, accelerate efforts to build high-level self-reliance and strength in science and technology, and make breakthroughs in core technologies. Moreover, China is gearing up to revitalize its digital economy, promote green i...
The above-mentioned cases allow us to assess the physical meaning of the configurational forces during the rearrangement of interatomic bonds i.e., bond dissociation and rotation in the presence of in-/out-of-plane externally imposed stretch, shear, bending and torsion. We use configurational force...

But, though the two words do in a few cases touch thus closely on each other, there is, on the whole, a marked distinction in our use of force and strength. ``Force is the name given, in mechanical science, to whatever produces, or can produce, motion.' --Nichol. Thy tears are ...
The specific meanings of the five areas of UHQD have been represented in Fig. 1. Fig. 1 The meaning of the five areas of urban high-quality development. Full size image Previous literatures have paid lots of attentions to UHQD variables’ recognition, which are mainly focused on economic ...
1]. Hence, the presence and value of particle physics in science. This, according to Frank Wilczek in his contribution to the special 20th century retrospective volume of Reviews of Modern Physics [10]. It has also been said that “The successful artificial production of Yukawa particles (...
In addition, there is also a resultant contact force acting on the bottom of the crate (and pushing upwards) due to contact with the floor. As explained before, this resultant force is the result of a pressure that acts over the area in contact with the floor. The bottom of the crate ...
