Why Does It Take Longer to Fly West?

The video explains why flights from east to west take longer than those from west to east. Despite Earth's rotation from west to east, which might suggest shorter westward flights, the reality is different due to Earth's spherical shape and varying rotational velocities. Jet streams, strong winds moving from west to east, significantly impact flight times, aiding eastward flights and making them faster and more fuel-efficient.

Explain how the rotational velocity of Earth varies from the equator to the poles.

What is the significance of the plane's initial velocity when taking off?
