Fundamentals of Physics I explores mechanics — kinematics, force, dynamics, conservation laws, and rotational motion — using trigonometric and vector methods.
What PHYS 121 covers
(For students majoring in a science. Fulfills the laboratory science requirement.) Prerequisite: MATH 107 or a more advanced mathematics course. An exploration of mechanics.
The aim is to apply the laws of physics to a broad range of motion-related physical phenomena. Topics include kinematics, force, dynamics, conservation laws, and rotational motion. Elementary trigonometric and vector properties are used.
Typical PHYS 121 assignments
Expect a problem set requiring you to apply a specific law of physics (such as a conservation law) to a motion-related physical phenomenon, using vector or trigonometric methods.
Key topics in PHYS 121
- Kinematics and dynamics
- Force and conservation laws
- Rotational motion
- Trigonometric and vector methods
Writing tips for PHYS 121
Follow the assignment instructions and rubric line by line
UMGC assignments for PHYS 121 are graded against a specific rubric or grading criteria your instructor provides — every requirement has to be visibly addressed. Skipping a requirement because it seems minor is one of the most common reasons a strong submission loses points.
Show your quantitative work, not just the final answer
PHYS 121 is graded on the method, not just the final numeric answer — skipping intermediate calculations or the underlying physical/chemical reasoning is one of the fastest ways to lose points, even when the final answer is correct.
Connect the physical principle to a real-world application
UMGC's lab science courses consistently grade whether you can connect the underlying physical or chemical principle to a real-world application or scenario — a correct calculation that stays purely abstract is missing a piece the rubric typically wants.

Why students seek help with PHYS 121
Students sometimes compute a physics problem's numeric answer without showing the vector/trigonometric reasoning PHYS 121 specifically requires — the rubric typically wants that method shown, not the final number alone.
