Introduction
This structured PHYS 165 Module 1 Exam format for 2026–2027 provides the complete
layout for generating high-quality exam-style questions with correct answers and
rationales. It emphasizes fundamental physics principles, kinematics, dynamics,
mathematical problem-solving, and Newton's laws critical to professional scientific
knowledge and successful Portage Learning course completion.
1. A car travels 50 km North and then 30 km South. What is the total displacement of
the car?
A. 80 km North
B. 20 km North
C. 20 km South
D. 80 km South
Rationale: Displacement is a vector quantity measuring the change in position. 50 km
(North) + (-30 km) (South/opposite direction) = 20 km North.
2. Which of the following is a fundamental SI unit?
A. Newton
B. Joule
C. Kilogram
D. Watt
Rationale: The kilogram (kg) is the SI base unit for mass. Newtons, Joules, and Watts are
derived units.
3. A ball is thrown vertically upward with an initial velocity of 15 m/s. What is its
velocity at the peak of its trajectory?
, A. 15 m/s
B. 9.8 m/s
C. 0 m/s
D. -15 m/s
Rationale: At the highest point of vertical motion, the instantaneous velocity is 0 m/s as the
object transitions from moving up to falling down.
4. According to Newton's Second Law of Motion, if the net force acting on an object is
doubled while the mass remains constant, the acceleration will:
A. Remain the same
B. Be halved
C. Double
D. Quadruple
Rationale: Newton's Second Law is F = ma. Force and acceleration are directly
proportional; doubling the force results in doubling the acceleration.
5. A vector has an x-component of 4.0 m and a y-component of 3.0 m. What is the
magnitude of the vector?
A. 7.0 m
B. 1.0 m
C. 5.0 m
D. 25.0 m
Rationale: The magnitude is calculated using the Pythagorean theorem: sqrt(4^2 + 3^2) =
sqrt(16 + 9) = sqrt(25) = 5.0 m.
6. A 10 kg box is pushed across a horizontal floor with a force of 50 N. If the coefficient
of kinetic friction is 0.2, what is the force of friction?
A. 2 N
