NAME: _________________________ PER: _______ DATE: ________CHAPTER 2MOTION IN ONE DIMENSIONCONCEPTS QUESTIONS1. Ball A is dropped from the top of a building. One second later ball B is dropped. As timeprogresses the difference in their __________________________.2. An object’s velocity can change directions when its acceleration is constant. An example ofthis is when an object, like a ball, is ______________. The velocity is positive going up andnegative going down. The acceleration will remain constant the entire time.3. Motion in the negative x direction is represented on an x vs. t plot by a _________________.4. Two objects are thrown from the top of a tall cliff. One is thrown up, and the other isthrown down, both with the same initial speed. Ignore air resistance, when the balls hitthe ground they are ____________________________5. When a ball is thrown straight up, its acceleration at the top is ___________________6. Two balls are thrown straight up. The first ball is thrown with twice the initial speed of thesecond. Ignore air resistance. The first ball will __________________ as far.7. Distance is to displacement as speed is to ____________________8. A horizontal line on an ______________________ versus time graph indicates that theobject is at a constant acceleration.9. A horizontal line on a _______________ versus time graph indicates that the object is at rest.10. Instantaneous speed is never _____________________.11. A ball, moves up along a smooth hill of ice will have the same acceleration, both _______ the hilland ___________ the hill.12. Galileo postulated that at a given location on the Earth and in the absenceof air resistance, all objects will fall with the ___________________________13. Acceleration is a vector quantity that represents the _______________________________14. If an object is traveling east with a decreasing speed, the direction of the object’sacceleration is ________________15. Objects A and B both start from rest. They both accelerate at the same rate. However, object Aaccelerates for twice the time as object B. Compared to the final ________ of object A to that ofobject B, object B is twice as fast.

16. An object can have increasing speed while its acceleration is decreasing. An example would bean object released from rest in the ____________________________17. A horizontal line on a __________ versus time graph indicates that the object is traveling at aconstant velocity, which means zero acceleration.18. A ball is dropped from the top of a building. A second ball is thrown straight down from thesame building. They are released at the same time. Neglecting air resistance the two balls_______________________________19. Oil drips at 0.5 second intervals from a truck thathas an oil leak. The pattern shown represents thespacing of oil drops as the car _______________uniformly from rest.20. An object is moving with constant acceleration in equal times its _________________________21. An object with zero acceleration ____________________________22. The distance time graph on the right represents the motion of an object sliding down a_________________________________23. Objects A and B both start from rest. They both accelerate at the same rate. However, object Aaccelerates for twice the time as object B. During the times that the objects are beingaccelerated, comparing the _______ traveled by object A to that of object B, object Atravels ______________24. The slope of a velocity versus time graph gives ___________________________25. A moving object must undergo a change of ____________________26. The slope of a position time graph gives __________________________27. An object’s velocity can _______________________ when its acceleration is constant.Example, when a rock is thrown straight up.28. When a ball is thrown straight up, its velocity at the top ____________________29. The distance time graph on the right compares distance as a function of time an object instraight-line motion. According to the graph, the object most likely has an ________________30. A skydiver jumps from an airplane. When she reaches terminal velocity, heracceleration is ________________________
