In this video, we clearly explain what torque is and how it works in physics. You'll discover that torque is the rotational equivalent of force — it causes objects to rotate around an axis. We break down the torque formula (τ = r × F × sinθ), the importance of the lever arm (moment arm), the direction of torque using the right-hand rule, and why the perpendicular component of force matters most. Using simple animations, everyday examples like wrenches, doors, and seesaws, and step-by-step calculations, this lesson makes the concept easy to understand.
Whether you're a high school or college student studying rotational motion, preparing for exams, or a hobbyist wanting to grasp the physics behind machines and tools, this tutorial removes the confusion around torque. By the end, you'll know how to calculate net torque, understand its relationship to angular acceleration and moment of inertia, and see real-world applications in engineering and everyday life.
