Toy Airplane Flying: Lift Force vs. Reaction Force

Click For Summary
SUMMARY

The discussion clarifies the relationship between lift force and reaction force in the context of a toy airplane flying in a horizontal circle. It establishes that the lift force is not the same as the reaction force; instead, the lift force equals the weight force plus the vertical component of the tension force in the cord. Additionally, the centripetal force acting on the airplane is identified as the horizontal component of the tension force. This distinction is crucial for understanding the dynamics of circular motion in aerodynamics.

PREREQUISITES
  • Understanding of basic physics concepts such as force and motion
  • Familiarity with centripetal force and its components
  • Knowledge of lift force and its role in flight dynamics
  • Basic comprehension of tension forces in circular motion
NEXT STEPS
  • Research the principles of circular motion in physics

Hi I've got a question concerning a previous question I've done. A person is holding a toy airplane which flys in the air with a constant radius.

is the lift force the same as reaction force?

is it equal to the vertical component of the centripetal force and weight force of the airplane?

Assuming the plane is flying in a horizontal circle of constant radius, the lift force is equal to the weight force plus the vertical component of the tension force in the cord. The centripetal force is the horizontal component of the tension force.
