Action, Reaction, Question! Newton’s Laws Quiz
How to answer the questions.
Students in Grades 10 to 12 in Papua New Guinea should master Newton’s Three Laws of Motion because they are fundamental concepts tested in national examinations and form the foundation of physics and science learning. These laws help students understand how forces, motion, acceleration, and inertia work in real-life situations, which are common topics in school assessments and external exams. A strong understanding of this concept improves problem-solving skills, especially in calculation questions involving force and motion that frequently appear in exam papers. In addition, mastering Newton’s Laws prepares students for future careers in engineering, aviation, mechanics, construction, maritime, and technical trades, which are important development sectors in PNG. Many STEM pathways at universities and technical colleges require a solid physics background, and Newtonian mechanics is a core entry-level topic. By learning these laws well, students not only perform better in exams but also build the scientific thinking and analytical skills needed for modern careers and national workforce demands.
