These are 100 original multiple-choice practice questions for PHYS 165 Module 7.
Since exact module content varies by institution, this set assumes Module 7 serves as
an advanced capstone and comprehensive review module covering all major
physics topics: mechanics, energy, momentum, rotational motion, fluids, oscillations,
waves, thermodynamics, electricity, magnetism, optics, and modern physics. They are
not official examination questions and are not copied from any textbook, test bank, or
copyrighted source.
Question 1:
Which of the following is a vector quantity?
A. Speed
B. Mass
C. Velocity
D. Temperature
Correct answer: C
Rationale:
Velocity has both magnitude and direction, making it a vector.
Question 2:
The SI unit of force is the:
A. Joule
B. Newton
C. Watt
D. Pascal
Correct answer: B
Rationale:
The newton (N) is the SI unit of force; 1 N = 1 kg·m/s².
Question 3:
A car travels 100 m east then 40 m west. Its displacement is:
,A. 60 m east
B. 140 m east
C. 60 m west
D. 140 m west
Correct answer: A
Rationale:
Displacement = 100 − 40 = 60 m east.
Question 4:
The slope of a velocity-time graph gives:
A. Displacement
B. Acceleration
C. Speed
D. Distance
Correct answer: B
Rationale:
The slope of velocity versus time is acceleration.
Question 5:
An object is dropped from rest. After 4 s, its speed is about:
A. 9.8 m/s
B. 19.6 m/s
C. 39.2 m/s
D. 78.4 m/s
Correct answer: C
Rationale:
v = gt = 9.8 × 4 = 39.2 m/s.
Question 6:
For a projectile on level ground, maximum range occurs at:
A. 30°
B. 45°
C. 60°
D. 90°
,Correct answer: B
Rationale:
R = v₀² sin(2θ)/g is maximum at θ = 45°.
Question 7:
Newton’s first law is also called the law of:
A. Acceleration
B. Inertia
C. Action-reaction
D. Gravity
Correct answer: B
Rationale:
Newton’s first law describes inertia.
Question 8:
A 10 kg object experiences a net force of 40 N. Its acceleration is:
A. 0.25 m/s²
B. 4 m/s²
C. 10 m/s²
D. 400 m/s²
Correct answer: B
Rationale:
a = F/m = 40/10 = 4 m/s².
Question 9:
The normal force on an object on a horizontal surface equals:
A. mg
B. ma
C. μmg
D. Zero
Correct answer: A
Rationale:
When no vertical acceleration exists, N = mg.
, Question 10:
On a frictionless incline of angle θ, acceleration is:
A. g
B. g sinθ
C. g cosθ
D. Zero
Correct answer: B
Rationale:
a = g sinθ on a frictionless incline.
Question 11:
Work is defined as:
A. Fd cosθ
B. Fd sinθ
C. F/d
D. F × t
Correct answer: A
Rationale:
W = Fd cosθ.
Question 12:
The work-energy theorem states that net work equals:
A. Change in momentum
B. Change in kinetic energy
C. Change in potential energy
D. Total energy
Correct answer: B
Rationale:
W_net = ΔKE.
