What do the following units represent? Use “d” for distance, “t” for time, “v” for velocity, or “a” for acceleration.
d 15. 14 km t 18. 6 hours d 21. 14 mi d 24. 1.4 m
v 16. 30 m/sa 19. 12 cm/s2 t 22. 3.2 sec a 25. 6 cm/min/sec
t 17. 34 min v 20. 150 mph d 23. 25 ft a 26. 3 km/hr/sec
- A Vector has both Magnitude anddirection.
- Define Displacement.
Change in position – how far you are from where you started, vector quantity.
- Define Velocity.Displacement traveled over time; rate of motion; vector quantity; speed plus direction.
- How is velocity different from acceleration?Velocity is the rate of distance traveled. Acceleration is the rate at which velocity changes.
- The proper units for acceleration arem/s2.
- The proper units for velocity arem/s.
33. Warren the whale, a speed swimmer, loves to race around the bay, which is 3.25 miles around. If he can swim 10 laps around the bay in 2 hours, what is his average speed?
G / U / E / S / S34. It takes Sally the squirrel, 20 seconds to travel from her favorite tree to her closest nut stash (a trip of 20meters), how far can she travel in 1 hour?
G / U / E / S / S35. At exactly3:00 pm, Herbie the Hermit Crab crawls onto a meter stick at the 8 cm mark. If he reaches the 78 cm mark at exactly 3:10 pm, what is his speed?
G / U / E / S / S36. If it takes Jumping Jack Flash 5 minutes to jump 12 blocks, how long will it take for him to jump 21 blocks?
G / U / E / S / S37. If Peggy the Pigeon travels eastward at 10 mph with a tail wind of 4 mph, what is her actual speed?
38. A semi truck is traveling at the speed of 10 m/s at the top of a hill. Five seconds later it reaches the bottom of the hill and is moving at 30 m/s. What is the rate of acceleration of the semi truck?
G / U / E / S / S39. Pete the Penguin loves to sled down his favorite hill. If he hits a speed of 19 m/s after 4 seconds, what ishis rate of acceleration? Hint: He starts at 0 m/s at the top of the hill.
G / U / E / S / S40. A runaway truck decelerates from 682 m/s to 0 m/s in 6 seconds. What is its rate of deceleration?
G / U / E / S / SWrite the letter of the proper vocabulary word in the blank for each statement.There are more words than definitions.
a. Acceleration#46 / 41. A t. Vector has both magnitude and direction.b. Meter#44 / 42. Your odometer tells youe. Distance, with no direction.
c. Second / 43. If you were to calculate the total distance you traveled on a trip, and divide by the total time it took you, you would find the r. Average Speed of your trip.
d. Average Velocity
e. Distance#42 / 44. The unit of displacement and distance is theb. Meter.
f. Meters per second#47 / 45. Instantaneous speed is different than instantaneous velocity because it lacksq. Direction.
g. Displacement#50
h. Instantaneous speed#49 / 46. The change in velocity per second isa. Acceleration.
i. Kinematics#52 / 47. Since velocity is measured in f. Meters per second, you have to make sure your time is in seconds.
j. Free Fall#48
k. miles per hour / 48. When an object is dropped from rest, it is inj. Free Fall.
l. Instantaneous Velocity / 49. Your speedometer tells you h. Instantaneous speed.
m. At rest#53 / 50. If you draw a straight line from where you started to where you ended up, you can measure yourg. Displacement.
n. Magnitude#54
o. Time#55 / 51. “g” is the acceleration due top. Gravity.
p. Gravity#51 / 52. The study of Motion isi. Kinematics.
q. Direction#45 / 53. If something is not moving it ism. At rest.
r. Average Speed#43 / 54. The n. Magnitudeof velocity is speed.
s. Stopwatch / 55. Distance divided by o. Time is speed.
t. Vector#41
56. Which object is going fastest?
57. The speed of a falling object, dropped from rest, 10 m/s every second.
- Increases by
- Decreases by
- Stays
58. The acceleration due to gravity is .
- Changing every second
- Equal to the velocity
- Depends on the time
- Constant
