An object's velocity can be described by its speed and acceleration.
True
False

When straight-line motion is considered, it is common to use speed and velocity interchangeably. When the direction is not changing, acceleration may be expressed as the rate at which speed changs. Speed and velocity are measured in units of distance per time. So it would make this answer false.
