Explaining Mechanics on Instagram: "The transmission (or gearbox) is a vital component of a vehicle’s drivetrain that connects the engine to the wheels, enabling the car to operate efficiently across different speeds and driving conditions. Core Purpose: Its primary function is to match the engine’s speed (RPM) to the vehicle’s road speed by adjusting the gear ratio, ensuring optimal power delivery and fuel efficiency. Gear Functions: • Low Gear (1st/2nd): Provides high torque to help the vehicl

Explainer Zone on Instagram: "Walter Lewin’s horizontal motion experiment demonstrates a fundamental principle of classical mechanics: the independence of horizontal and vertical motion (inertia). In this experiment, a ball is launched vertically upward from a machine moving horizontally at constant velocity. Despite the machine’s motion, the ball falls back into it, illustrating that horizontal velocity does not affect vertical free fall. Unlike everyday intuition (where the machine might seem
