What about with constant speed?
Theoretically, and if you were going slow enough, I'm sure you could keep your velocity and speed constant. Or am I missing something fundamental?

Constant velocity? No.
Constant speed? Yes.
You have to remember velocity is speed and direction, and going in a circle, your direction changes at every point, therefore your velocity can never be constant even though your speed could be.
On a race track you could have constant velocities at certain points since the track is not a perfect circle, but overall you will not have a constant velocity if you make one lap around the track.

No. Not with constant velocity. Velocity is a vector. A drag racer can proceed with constant velocity. A circle track driver will find himseld off of the track pronto at copnstant velocity. In turning, the velocity (per direction) changes.
Constant speed is possible. As long as it is low enough to maintain control of the vehicle, the speed can remain constant....while the velocity changes as he turns.

Constant velocity is impossible, because the very act of turning means that you're accelerating (in this case, towards the centre of the track). A constant velocity requires that you travel in a straight line.
Constant speed is different - direction is not important - so, sure, that's possible. (it may not be easy, but these sorts of questions don't really care about the practicalities!).

If I remember correcly from physical science years ago, velocity is speed in a given direction. So, I'd say that you couldn't have constant velocity, but you could have constant speed. Hmmm...... Then I think about orbital velocity...

An merchandise is unaccelerated if and on condition that it strikes in a at recent line at consistent velocity, or under no circumstances. Uniform around action ability that the object is being speeded up in a course perpendicular to its process commute (velocity vector). it incredibly is observed as centripetal acceleration.

It is possible since when moving in a circle the acceleration is towards the center of the circle, perpendicular to the speed vector, i.e it does not affect the speed, which remains constant.

If the track was a perfect circle, then yes, it could maintain a constant speed... I think...

yes it is. but that speed will depend on tempature, tire area that touched the pavement and the latteral G forces on the car, and the coheasioin factor of the tire to the track. This would make a great theasus study for you.

Hi. If the track were at an angle then that would be easy. If flat then there are slippages to worry about. (Race track implies speed, no?)
