9J D. 50J Correct Answer A. 0.5J Explanation The work done on an object can be calculated by multiplying the force applied to the object by the distance it moves in the direction of the force. In this case, the force applied by the player's foot is 5N and the distance the ball rol...
gain energy and move faster but the energy was still conserved and never destroyed for energy pretend the system has ...zero internal initial energy so that you only worry about the other forms of energy, then we can solve for how much internal energy changes in the problem work an object...

In this course, you will learn the fundamentals and applications of physics for class 11 and 12. You will learn how to: Apply the concepts of kinematics, dynamics, work, energy and power to analyze the motion of objects and systems 🚗 Use the concepts of rotational motion, gravitation, el...
Metasurfaces are established tools for manipulating light and enhancing light-matter interactions, but the loss of conventional meta-atoms usually limits the performance potential of metasurfaces. Here, the authors propose a class of metasurfaces based on discretized meta-atoms able to mitigate the rad...

Today’s high-energy particle accelerators can be several kilometres in length, cost hundreds (or even thousands) of millions of dollars, and accelerate particles to enormous energies (trillions of electron volts). Experimental teams, such as those that discovered the W+, W−, and Z quanta ...
The authors enhance energy storage performance in tetragonal tungsten bronze structure ferroelectrics using a multiscale regulation strategy. By adjusting the composition and sintering process of BaSrTiNb2-xTaxO9 ceramics, they introduce grain refinement and perovskite second-phase precipitation. Jiaming Liu...
In this scenario, the current work presents a comparative investigation of data-driven, physics-based, and hybrid models for the fatigue lifetime prediction of structural adhesive joints. The different modeling approaches are compared in terms of complexity of implementation, sensitivity to data size,...
Chameleon particles are a candidate for a class of scalars whose mass depends on their environment [19]. If they are created in the vacuum vessel of the experiment by photons passing through a magnetic field, they will be trapped in the vessel due to energy conservation. They may be reconve...
