SUMMARY

The discussion centers on the forces acting on a model rocket with a deployed parachute. It is established that the parachute does exert an upward force, primarily due to air resistance, which is significantly influenced by the parachute's large surface area. This upward force, often referred to as air drag, counteracts the downward force of gravity acting on the rocket. Understanding these forces is crucial for analyzing the motion of the rocket during its descent.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with free body diagrams
  • Knowledge of air resistance and drag forces
  • Basic principles of projectile motion
NEXT STEPS
  • Study the concept of air resistance in fluid dynamics
  • Learn how to draw and interpret free body diagrams
  • Explore the effects of surface area on drag force
  • Investigate the principles of parachute design and deployment
USEFUL FOR

Students in physics, educators teaching mechanics, and anyone interested in the dynamics of falling objects and parachute systems.

Homework Statement



A model rock is shot into the air. Once it starts to fall a parachute is deployed. Draw a free body diagram of the rocket with the parachute deployed

Homework Equations





The Attempt at a Solution



ok well there is gravity
does the parachute exert a force upward? onto what? what do i call this force?
 
Physics news on Phys.org


it's not directly the parachute which causes the force upwards, all the parachute does is act as a huge sheet of strong paper above you, it's the air resistance which acts so much on the parachute (because it has a huge surface area- which is the determining factor for air resistance) which causes the upward force, you could also call it air drag.

is that all you need to know?
