The curved flight of fighter planes at high speed requires a large:
Correct answer: C. Centripetal force
- A. Gravitational force
- B. Frictional force
- C. Centripetal force
- D. Centrifugal acceleration
Explanation
The correct answer is option C: Centripetal force. Fighter planes in curved flight require a large centripetal force directed towards the centre of the circular path to keep them in their trajectory. Gravitational force, frictional force, and centrifugal acceleration are not the primary forces involved in maintaining the curved flight of the planes.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
