False. The displacement of an object is found by subtracting the start position from the end position. 12. False. The average velocity of an object in motion is its total displacement divided by the total time taken for the motion. 13. False. Motion with non-uniform velocity is called accelerated motion. 14. True 15. False. Instantaneous velocity is the velocity of an object at a specific instant in time. 16. False. The area under an acceleration-time graph gives the change in velocity of that time period. 17. True
