Question

complete the analogy: 1. speed: velocity;______:______ a. acceleration:velocity b. distance:displacement c. speed:acceleration d. time:scalar 2. positive acceleration:_____: zero acceleration:constant velocity a. constant speed b. decreasing velocity c. increasing velocity d. zero velocity

Answer 1

Velocity is the vector,
     made up of the scalar speed + direction of speed

b).  Displacement is the vector,
           made up of the scalar distance + direction of distance

Answer 2

B.
distance is used to calculate speed

displacement is used to calculate velocity
