## Main Question or Discussion Point

If we have two twins driving cars.

They remain at the same height above sea level so gravitational time dilation is equal.

Both cars travel at the same speed so time dilation due to speed is equal for both.

However...

Car A drives around a small circular race track and experiences centripetal acceleration. Car B drives is a straight line and does a circuit of the globe.

Will car A age slower due increased angular acceleration it experiences?

Thanks.
