SUMMARY

When driving in a circle, objects inside the vehicle appear to move outward due to inertia, which is the tendency of objects to maintain their straight-line motion. This phenomenon is explained by Newton's first law of motion, which states that an object in motion will remain in motion in a straight line unless acted upon by an external force. Passengers in a car feel as if they are being pulled outward because they are trying to maintain their straight-line trajectory while the car turns. This is evident when observing a motorcyclist who, if falling off mid-corner, continues in a straight line rather than moving outward.

PREREQUISITES
  • Understanding of Newton's first law of motion
  • Basic knowledge of circular motion dynamics
  • Familiarity with concepts of inertia and acceleration
  • Awareness of the effects of centrifugal force in non-inertial frames
NEXT STEPS
  • Research the principles of circular motion and centripetal acceleration
  • Study the effects of inertia in various physical scenarios
  • Explore the relationship between acceleration and direction in physics
  • Learn about non-inertial reference frames and their implications
USEFUL FOR

Physics students, educators, automotive engineers, and anyone interested in understanding the dynamics of motion in circular paths.

What i am wondering if driving in a circle if the mass of the object moving, why is it drawn outward because the current acceleration is in forward motion?

When you drive in a circle, there will be a component of acceleration towards the center of the circle (otherwise you'd keep going in a straight line). Remember that acceleration doesn't just mean a change in speed--a change in direction is also an acceleration.

From inside the car it feels like you are being pulled outward, just like it feels like you are being pushed backwards when you floor the gas pedal.

Well it isn't drawn outward at all. Everything inside the car is just trying to move in a dead straight line. Objects don't like to go in circles at all, they like straight lines.
It's the first law of mechanics, a very simple fact, beautiful, and first noticed by guys like Galileo 500 years ago.

Watching a car from the pavement: the passengers always look like they just want to go straight rather than be carried with the car into the corner.

If a motorcyclist falls off his bike in mid-corner, he moves in a dead straight line into the sand trap. He certainly doesn't move outward.

So, it's not trying to move outward at all, what it's really trying to do is move in a perfect straight line whilst the car is moving inward.
