UPDATED QUESTIONS AND CORRECT
ANSWERS.
A car is moving forward, and its brakes are being applied. Which statement is true?
The car's velocity is backward, and its acceleration is backward.
The car's velocity is forward, and its acceleration is forward.
The car's velocity is backward, and its acceleration is forward.
The car's velocity is forward, and its acceleration is backward. - ANS The car's velocity is
forward, and its acceleration is backward.
Explanation:
The car is moving forward, so its velocity is also forward. However, it is also slowing down, so its
acceleration is backward.
Which statement describes inertia?
Inertia is an object's general weight.

, Inertia is an object's resistance to being stationary.
Inertia is an object's tendency to move when force is applied. - ANS Inertia is an object's
tendency to remain stationary.
Explanation:
Inertia is an object's tendency to remain stationary or continue moving in the same way.
You are pushing a file cabinet across a floor in a straight line at a constant speed. What can you
correctly conclude about the forces acting on the file cabinet?
The force that you are exerting on the file cabinet is greater than the force of friction combined
with the cabinet's weight.
The force that you are exerting on the file cabinet is equal and opposite to the force that
friction is exerting on it.
The force that you are exerting on the file cabinet is greater than the force that friction is
exerting on it.
If you were to exert twice as much force on the file cabinet, it would slide across the floor at
twice its original speed. - ANS The force that you are exerting on the file cabinet is equal and
opposite to the force that friction is exerting on it.
Explanation:
The force that you are exerting on the file cabinet is equal and opposite to the force that
friction is exerting on it.
