51. Objects starting and ending on the same point has a zero displacement.
52. A ball tied with a string and whirled in a circular path has a uniform velocity but did not experience
acceleration.
53. Distance and displacement are the two important considerations in determining the velocity of an
object.
54. A motorcycle is moving at a velocity of 60km/h. After 30 minutes it slows down and completely stops.
The motorcycle's acceleration is negative.
_55. All things here on Earth are moving with reference to the sun because the earth is rotating around the
sun.
56. Speed is a change in position with respect to a reference point.
57. We can say that an object is moving when there is change in position, distance, and direction.
_58. We can say that an object is accelerating when it speeds up, changes direction, or slows down.
_59. Graph is used to represent different speed.
60. Distance is the straight-line distance from the starting point to the end point.
61. Acceleration is the rate of change in velocity.
62. The unit used for measuring time is called second.
63. Through graph we can identify the speed of runners.
64. The position of objects is described by their coordinates along the number line.
65. Velocity refers to the entire path that object travelled.
66. Energy travels in waves.
67. The low points of a transverse wave are called crest.
68. The distance between any two troughs or peaks is called the wavelength.
69. Longitudinal waves move by pushing forward and pulling back.
