Here's why:
* Centripetal force: This is any force that acts towards the center of a circular path, causing an object to move in a circle.
* Lift force: This is the upward force generated by the wings of an aircraft, which is perpendicular to the direction of motion.
When a plane is flying in a circular path, the lift force isn't perfectly vertical. It's tilted slightly inwards, towards the center of the circle. This tilted component of the lift force acts as the centripetal force, keeping the plane moving in a circular path.
Think of it like this:
Imagine you're swinging a ball on a string. The string is providing the centripetal force, pulling the ball towards the center of the circle. In the case of an airplane, the lift force acts like the string, pulling the plane inwards towards the center of the circular path.
Important Note: The angle of the lift force, and therefore the amount of centripetal force, is controlled by the pilot using the ailerons and rudder.
