Displacement is

• The resultant straight distance is at the initial position only

• The resultant straight distance is at the final position only

• The resultant straight distance from the start position to the end position

• Resultant straight distance

Acceleration is

• Change in speed in a certain time unit

• Change in velocity in a certain time unit

• Change in distance in a certain time unit

• Changes in movement within a certain time unit
