SUMMARY

The forces acting on passengers in the back seat of a car are fundamentally similar to those experienced by front seat passengers, particularly during straight movement. However, variations arise during turns due to the rocking motion of the vehicle and the differing radii of circular motion for inner versus outer passengers. Key factors influencing these differences include wheel placement and the dynamics of the vehicle's motion. Understanding these forces is essential for analyzing passenger safety and comfort in automotive design.

PREREQUISITES
  • Basic understanding of Newton's laws of motion
  • Familiarity with vehicle dynamics
  • Knowledge of circular motion principles
  • Experience with measuring forces using accelerometers
NEXT STEPS
  • Research vehicle dynamics and passenger safety during turns
  • Explore the use of accelerometers for measuring forces in vehicles
  • Study the effects of wheel placement on vehicle stability
  • Investigate the principles of circular motion in automotive contexts
USEFUL FOR

Automotive engineers, safety analysts, and physics students interested in vehicle dynamics and passenger safety considerations.

are the forces acting on the passenger seating in the back seat of the car different from the forces acting on the passenger that seats right in front of him and how to measure them, for example in cases when the car is turning or when the car is moving straight?
 
Physics news on Phys.org
The forces are pretty much the same. The differences come from rocking of the car, from the fact that the inner passengers move in a smaller circle than the outer ones in a corner, placement of the wheels and a few of such things but that is nitpicking.
