Since velocity is a vector quantity, it consists of both magnitude (speed) and direction. Therefore, a change in either the magnitude or the direction of motion is defined as acceleration.

Richard Feynman was awarded the 1965 Nobel Prize in Physics, sharing it with Julian Schwinger and Sin-Itiro Tomonaga. He received the prize for his fundamental work in quantum electrodynamics (QED), which revolutionized how scientists calculate the interactions between light and matter. His work solved long-standing mathematical problems, famously introducing "Feynman diagrams" for visualizing quantum interactions.

No one truly understands quantum physics in an intuitive, conceptual way, but physicists understand how to use its mathematics with extreme precision to predict outcomes. It is considered the most successful scientific theory, powering technologies like lasers and MRIs, yet its fundamental nature remains debated, with phenomena like superposition and entanglement defying everyday logic.

is there any questions u dont understand above? if yes lemme know in comments, 12 am I will explain.

the 48km one, u dont have to worry if u dont understand, its not important for now. but if u insist to understand it, feel free to ask.

Hye hyee I'm back with the quizzes!!. Sorry ye tgh tgh malam bagi kuiz,siang bz sikit😇
