WGU C165 OBJECTIVE ASSESSMENT AND PRE-
ASSESSMENT NEWEST 2026 TEST BANK| C165
INTEGRATED PHYSICAL SCIENCES OA AND PA EXAM
WITH 650 REAL EXAM QUESTIONS AND CORRECT
VERIFIED ANSWERS/ ALREADY GRADED A+ (MOST
RECENT!!)
1. A car accelerates from rest to 20 m/s in 5 seconds. What is
its acceleration?
A) 2 m/s²
B) 4 m/s²
C) 5 m/s²
D) 100 m/s²
Answer: B) 4 m/s²
Rationale: Acceleration = change in velocity / time = (20 m/s -
0 m/s) / 5 s = 4 m/s².

,2. Which Newton's law explains why a book remains on a
table unless pushed?
A) First law (inertia)
B) Second law (F=ma)
C) Third law (action-reaction)
D) Law of universal gravitation
Answer: A) First law (inertia)
Rationale: Newton's first law states an object at rest stays at rest
unless acted upon by an external force.
3. A 10 kg box is pushed with 50 N of force. Friction is 10 N.
What is the net force?
A) 10 N
B) 40 N
2
,C) 50 N
D) 60 N
Answer: B) 40 N
Rationale: Net force = applied force - friction = 50 N - 10 N =
40 N.
4. Which has the greatest inertia?
A) A baseball
B) A bicycle
C) A car
D) A paper clip
Answer: C) A car
Rationale: Inertia depends on mass. The car has the largest
mass, thus greatest inertia.

, 5. A ball is thrown upward. At the top of its path, its velocity
is zero. What is its acceleration?
A) 0 m/s²
B) 4.9 m/s² downward
C) 9.8 m/s² downward
D) 9.8 m/s² upward
Answer: C) 9.8 m/s² downward
Rationale: Gravity constantly accelerates objects downward at
9.8 m/s², even at the peak.
6. Which energy conversion occurs in a battery-powered
flashlight?
A) Chemical → electrical → light
B) Electrical → chemical → light
C) Light → electrical → chemical
D) Mechanical → electrical → light
