Physics Grade 10. Elements of the special theory of relativity. Collection 1

Course Difficulty Icon Intermediate
Course Type Icon Course
Course Duration Icon 4 hours

This interactive course introduces Grade 10 students to the core principles of the Special Theory of Relativity. Learners study Einstein’s postulates, the relativistic law of velocity addition, and the key consequences of relativistic physics, including time dilation, length contraction, and the relationship between mass and energy. The course includes interactive tests and control questions that help students consolidate knowledge, assess their progress, and deepen conceptual understanding. Through structured explanations, guided problem-solving, and systematic review, students develop a clear grasp of how relativistic mechanics expands and redefines classical ideas about space, time, and motion.
