Deriving Escape Velocity of Planet Earth

The video tutorial explains the concept of escape velocity, the minimum speed needed for an object to break free from a planet's gravitational pull without air resistance or rotation. It uses the conservation of mechanical energy to derive the escape velocity formula, considering gravitational potential energy. The tutorial calculates Earth's escape velocity as approximately 11.2 km/s or 25,000 mph, emphasizing that this speed is independent of the object's mass. The lesson concludes by linking escape velocity to the planet's binding energy.
