Is there a relationship between speed and acceleration?
Is there a relationship between speed and acceleration? Speed is the distance covered in a unit of time while acceleration is the rate of change of speed. The unit of speed in the metric system is meters per second (m/s) while that of acceleration is meters per second squared (m/s2). Speed is a scalar quantity […]
