So if we have a constant force we can't have a constant velocity and the instantaneous power is not constant with time for the system. Lets say the velocity vector is constant with time...That leads to the net force being zero on the system and the power involved for the system is ze...
For this one, am i supposed to use W = change in KE where i calculate work as ((F - friction - mgsintheta) times d), or am i supposed to do the change in -mgh plus Wfriction = change in KE (where if it is in this case, is the friction going to be a negative number?) ...

Cavity-enhanced energy transport in molecular systems The authors discuss the physics underlying the enhancement of energy transfer and energy transport in molecular systems and identify key questions and theoretical challenges for future research.
Work, energy and power are essential concepts in physics. Work is the displacement of an object caused by a force (push or pull). Energy is defined as the ability to perform work. We also get to know about the work done formula and energy formula. 👉 After taking the JEE Main exam,...
Conceptual Questions Explain why it is easier to climb a mountain on a zigzag path rather than one straight up the side. Is your increase in gravitational potential energy the same in both cases? Is your energy consumption the same in both? Do you do work on the outside world when you ...
Quantum physics is the study of matter and energy at its most fundamental level. A central tenet of quantum physics is that energy comes in indivisible packets called quanta. Quanta behave very differently to macroscopic matter: particles can behave like waves, and waves behave as though they are...
Measurement of interfacial thermal resistance in high-energy-density matter Heat transport across interfaces can be restricted due to interfacial thermal resistance between different materials. Here, authors find experimental evidence of a significant and enduring heat barrier between two high-energy-density...
