SUMMARY

A car traveling north that makes a right turn to head east demonstrates the principles of momentum and friction. The tires create a frictional force with the road that not only changes the direction of the car but also exerts a slight influence on the Earth due to its mass. This interaction is crucial for understanding how tires offset lateral forces (py) while generating forward momentum (px). The discussion highlights the complex dynamics involved in vehicle motion and the subtle effects on the surrounding environment.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Basic knowledge of friction and its role in vehicle dynamics
  • Familiarity with the concept of momentum in physics
  • Awareness of the relationship between mass and force
NEXT STEPS
  • Research the principles of Newton's laws of motion in relation to vehicle dynamics
  • Study the effects of friction on tire performance and vehicle handling
  • Explore the concept of momentum and its applications in automotive physics
  • Investigate the influence of mass on force and motion in real-world scenarios
USEFUL FOR

Physics students, automotive engineers, and anyone interested in understanding the mechanics of vehicle motion and the forces at play during turning maneuvers.

A car traveling north makes a right turn, to head east.
How do the tires completely offset py and simultaneously create px?
(If the tires merely acted like guidance jets, it might turn to face east but continue traveling north.

The frictional force between the tyres and the road starts the Earth moving north and west. Since the Earth is a lot more massive than the car, the movement is very slight.

Not the "friendly" sort of answer that PF proclaims...
Usually work through questions on my own; thought there might be someone who's been there ahead of me. Here's the sort of thing I was thinking about: https://en.wikipedia.org/wiki/Circle_of_forces
