Directions: Complete the paragraph by filling in the blanks. Because the velocity of an object depends on 7.
as well as
8.
, the velocity of an object can change even as the
9.
of the object remains constant. Imagine race cars going around an
oval track. Even if their 10.
remains constant, their velocity changes
because the 11
of their motion is changing.
If a car is traveling on a street and slows down, its speed 12.
and the
car has negative 13.
Then the car speeds up, giving it positive
14
When the car was slowing down, the 15.
was in the opposite 16.
of the 17.
To calculate a change in velocity, subtract the 18.
from the
19.
If the direction of motion does not change and the object moves in
a straight line, the change in velocity is the same as the change in 20.
