As with philosophy, the study of religion underscores how humankind has long speculated about its origins. The possibility of a higher being (or beings) to which livings things owe their existence has long captived human thought. Many religions also offer their own views on the nature of good and evil, and they may prescribe guidelines and judgment on different kinds of human behavior.","image":{"id":0,"url":"/95/180595-050-EDF2CA3A.jpg","altText":"Philosophy & Religion","fullUrl":"https://cdn.britannica.com/95/180595-050-EDF2CA3A.jpg"}},"typeDisplayName":"Text Multiple Choices"}] ,"quiz": {"id":4526,"generalAudience":false,"popular":false,"vocab":false,"categories":[{"label":"Science","slug":"Science"}],"type":"TEXT_MULTIPLE_CHOICE","image":{"altText":"Italian-born physicist Dr. Enrico Fermi draws a diagram at a blackboard with mathematical equations. circa 1950.","credit":"National Archives, Washington, D.C.","fullUrl":"https://cdn.britannica.com/01/115001-131-7278E518/Enrico-Fermi-Italian-problem-physics-1950.jpg"},"title":"Physics and Natural Law","timed":true,"seconds":10,"questions":[{"text":"Which branch of physics is particularly useful in designing bridges?","correctAnswerIndex":1,"answers":["quantum physics","statics","mechanics","statistics"],"difficulty":1,"explanation":"Statics is the study of matter at rest. Statics deals with the balancing of forces with appropriate resistances to keep matter at rest. The design of buildings and of bridges are examples of problems in statics."},{"text":"In what year was the second theory of relativity published?","correctAnswerIndex":1,"answers":["1949","1916","2001","1848"],"difficulty":3,"explanation":"In 1916 Albert Einstein published his second (or general) theory of relativity.

Statics deals with the balancing of forces with appropriate resistances to keep matter at rest. The design of buildings and of bridges are examples of problems in statics.</dd> </dl> <dl> <dt>Question: In what year was the second theory of relativity published?</dt> <dd>Answer: In 1916 Albert Einstein published his second (or general) theory of relativity. </dd> </dl> <dl> <dt>Question: In physics, for every action there is an equal and opposite what?</dt> <dd>Answer: Newton’s third law of motion holds that for every action, there is an equal and opposite reaction.</dd> </dl> <dl> <dt>Question: Which of these forces slows motion?</dt> <dd>Answer: Friction is the force that resists or acts against movement. Friction on an automobile brake slows the motion of the vehicle.</dd> </dl> <dl> <dt>Question: What theory is Albert Einstein known for?</dt> <dd>Answer: Einstein’s theory of relativity shows that measurements of space and time are relative—that is, they change when taken by observers who are moving at different speeds. </dd> </dl> <dl> <dt>Question: Who developed the laws of motion?</dt> <dd>Answer: Sir Isaac Newton (1642–1727) developed the laws of motion, describing the movements of objects in space.</dd> </dl> <dl> <dt>Question: Who received the 1951 Nobel prize in physics?</dt> <dd>Answer: Ernest Walton received the 1951 Nobel prize in physics for the development of the first nuclear-particle accelerator.</dd> </dl> <dl> <dt>Question: With what phenomenon is the physicist Benjamin Thompson associated?</dt> <dd>Answer: Benjamin Thompson reasoned that motion is transformed into heat (as when a bullet strikes through a piece of wood) and that heat is not an element or a substance. </dd> </dl> <dl> <dt>Question: What kind of energy is contained in a rock on a cliff?</dt> <dd>Answer: Potential energy is stored in a rock on a cliff and in a stretched bowstring. If the cliff crumbles, the rock falls. If the string is let go, it pushes the arrow through the air.</dd> </dl> </div> <div class="container"> <div class="grid"> <div class="col pt-sm-20"> <script type="application/ld+json"> { "@context" : "https://schema.org", "@type" : "BreadcrumbList", "itemListElement" : [ { "@type" : "ListItem", "position" : 1, "item" : { "@id" : "https://www.britannica.com/quiz/browse", "name": "Games & Quizzes" } } , { "@type" : "ListItem", "position" : 2, "item" : { "@id" : "https://www.britannica.com/quiz/browse/Science", "name": "Science Quizzes" } } ] } </script> <nav class="breadcrumb quiz-breadcrumb mt-10 mt-sm-0 mb-10 mx-auto"> <span class="breadcrumb-item "> <a href="/" class="">Home</a> </span> <span class="breadcrumb-item "> <a class="" href="/quiz/browse">Games & Quizzes</a> </span> <span class="breadcrumb-item "> <a class="" href="/quiz/browse/Science">Science Quizzes</a> </span> </nav> <div class="md-quiz mx-n20 mx-sm-auto shadow-lg rounded" id="quiz-root" data-bc-category="Science"> <div class="md-quiz-skeleton" style="--aspect-ratio: 900/675"></div> </div> <div class="md-extra-quiz-content mx-auto mb-10"> <div id="intro" class="mt-10"> <a class="font-14 d-inline-flex align-items-center font-weight-bold mb-10" href="https://cam.britannica.com"> <em class="material-icons mr-5" data-icon="star" style="font-size: inherit"></em> Save your scores!
