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
B.
distance is used to calculate speed
displacement is used to calculate velocity
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
