This leaves room for some acceleration of the pace of withdrawals, an option the White House is reported to be considering.
It has three sensors which track steps, acceleration, and altitude.
Jones, the face of the burgeoning organization, has been taken aback by the acceleration of interest.
The rate of change of the velocity of a moving body. An increase in the magnitude of the velocity of a moving body (an increase in speed) is called a positive acceleration; a decrease in speed is called a negative acceleration. Acceleration, like velocity, is a vector quantity, so any change in the direction of a moving body is also an acceleration. A moving body that follows a curved path, even when its speed remains constant, is undergoing acceleration. See more at gravity, relativity.
