In this video, we’ll break down how to solve physics problems involving the motion of a 2D spring. Learn about the forces at play, how to model the spring’s movement, and the key concepts behind ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...

The picosecond ultrasonics technique to probe atomic bonds and vdW forces in In 2 Se 3. In the experiment, blue-coloured pump laser pulses are shone on a flake of 2D material, and red-coloured probe ...

Rapid industrialization advancements have grabbed worldwide attention to integrate a very large number of electronic ...

The right part shows typical Brownian motion trajectories in 2D of the nanowire tip (2 s acquisition). The nanowire undergoes an extra external force F ext (r 0 + δr), which is assessed at the ...

The lack of a clinically viable method to track and direct cancer drugs to tumors is a big problem for targeted therapeutics. But a new ultrasonic method proposed by biomedical engineers from Qifa ...
