(a) Displacement is a __________ quantity, whereas distance is a __________ quantity.
(b) The physical quantity that includes both the speed and direction of the motion of a body is called its __________.
(c) A motorcycle has a steady __________ of 3 m/s². This means that each __________ its __________ increases by __________.
(d) Velocity is the rate of change of __________. It is measured in __________.
(e) Acceleration is the rate of change of __________. It is measured in __________.

Answer 1

(a) Displacement is a vector quantity, whereas distance is a scalar quantity.
(b) The physical quantity that includes both the speed and direction of the motion of a body is called its velocity.
(c) A motorcycle has a steady acceleration of 3 m/s². This means that each second its velocity increases by 3 m/s.
(d) Velocity is the rate of change of displacement. It is measured in m/s.
(e) Acceleration is the rate of change of velocity. It is measured in m/s².
