1. The rate of change of displacement is called   acceleration   speed   velocity   force   Hint Half-n-half Clue   2. The rate of change of velocity is called   force   momentum   acceleration   speed   Half-n-half Clue   3. Acceleration = (change in _______) / (time taken for that change)   velocity   speed   displacement   force   Half-n-half Clue   4. If velocity is measured in meters per second and time in seconds, then the units of acceleration are   second2 / meter   meter / second2   second / meter   meter / second   Half-n-half Clue   5.
