1) when we steer a car, the front wheels point to the direction we steered in. why does steering change a car's velocity?
does it have something to do with the angular velocity, momentum, or even torque?
-i tried to think of the individual forces that act on each wheel, and all i have is the normal force, gravity, and perhaps friction. (not sure if there is some other forces)
2) and sometimes, we can oversteer and understeer. can someone explain to me how and why this occurs?
i know understeer is kinda like drifting, but how does it happen? why does the locking of the wheels cause us to lose control of the car? (lose control as in the car slides sideways when the wheels lock)
3) why is it right to brake when entering a curve, and then accelerating out of the curve? why can't we just apply throttle throughout the entire turn?
