Can Someone Help Me With PHY-111?
Yes. We handle every component of GCU’s General Physics I—homework assignments, PHY-111L lab reports, and exams. Physics is pure problem-solving: kinematics, Newton’s laws, energy, momentum, rotational motion. These are calculation-heavy topics where our experts excel. A/B guaranteed or your money back.
Physics Is Problem-Solving. That’s What We Do.
Every topic requires setting up equations and solving for unknowns. We’ve done thousands of these problems.
What Is PHY-111 at GCU?
PHY-111 (General Physics I-Lecture) is GCU’s algebra-based introductory physics course. It’s a 3-credit lecture course that runs alongside PHY-111L, a separate 1-credit hands-on laboratory course. Together they fulfill lab science requirements for many programs and serve as prerequisites for advanced science coursework.
This is classical mechanics: how objects move, why they move, and how energy and momentum are conserved. The math is algebra and trigonometry—no calculus required (that’s PHY-121). But “algebra-based” doesn’t mean easy. You’re solving multi-step word problems that require translating physical situations into mathematical equations, then solving systems of equations under time pressure.

PHY-111 vs. PHY-121: What’s the Difference?
PHY-111/112 (General Physics) is algebra-based—designed for pre-health, life science, and non-engineering majors. PHY-121/122 (University Physics) is calculus-based—required for physics, engineering, and chemistry majors. Both cover the same topics, but PHY-121 uses derivatives and integrals. If your program requires PHY-121, we handle that too.
What PHY-111 Covers
PHY-111 is classical mechanics—the physics of motion, forces, and energy. Every topic builds on the previous one, which means falling behind early creates a snowball effect.
Kinematics
Motion in one and two dimensions. Position, velocity, acceleration. The kinematic equations. Projectile motion. Relative velocity. This is the foundation—if you don’t master kinematics, everything else falls apart.
Newton’s Laws of Motion
Where most students struggle. Free-body diagrams, friction, tension, normal force, inclined planes, connected objects. You must be able to identify all forces, set up F=ma equations, and solve systems of equations.
Work and Energy
Work done by forces, kinetic energy, potential energy (gravitational and elastic), conservation of mechanical energy, power. Energy methods often provide easier solutions than Newton’s laws—if you know when to use them.
Momentum and Collisions
Linear momentum, impulse, conservation of momentum, elastic and inelastic collisions in 1D and 2D. Center of mass. These problems require careful attention to signs and directions.
Circular Motion
Uniform circular motion, centripetal acceleration and force, banked curves, vertical circles. Understanding that centripetal force isn’t a new force—it’s the net force pointing toward the center.
Rotational Motion
Angular kinematics, torque, moment of inertia, rotational equilibrium, angular momentum. The rotational analogs of linear motion—similar equations, different variables.
Fluids and Buoyancy
Density, pressure, Pascal’s principle, buoyant force, Archimedes’ principle. Bernoulli’s equation for fluid flow. Applications to hydraulics and floating objects.
Waves and Thermodynamics
Ideal gas law, standing waves on a string, wave properties. These topics often appear at the end of the course and on the final exam.
Where PHY-111 Students Get Stuck
Free-Body Diagrams and Newton’s Laws
Newton’s second law (F = ma) looks simple. Applying it to real problems is not. Students struggle with identifying all the forces acting on an object, drawing accurate free-body diagrams, and setting up equations for connected systems.
The problem-solving framework:
- Draw a picture — Sketch the physical situation
- Isolate the object — Draw a free-body diagram for each object
- Choose coordinates — Align axes with motion direction (often along inclines)
- Apply ΣF = ma — Write equations for x and y components separately
- Solve the system — Often 2-3 equations with 2-3 unknowns
Common errors: Forgetting the normal force. Adding friction in the wrong direction. Not recognizing that connected objects have the same acceleration. Confusing weight (mg) with mass (m).
Projectile Motion
Projectile motion combines horizontal (constant velocity) and vertical (constant acceleration) motion. Students must decompose initial velocity into components, apply kinematic equations separately for each direction, and recognize that time connects the two.
Key insight: Horizontal and vertical motions are independent. The horizontal velocity doesn’t affect how fast the object falls. The vertical acceleration doesn’t affect horizontal speed.
- Horizontal: x = v₀ₓt (no acceleration)
- Vertical: y = v₀ᵧt – ½gt² (acceleration = -g)
- Connection: Same time (t) in both equations
Energy Conservation
Energy problems can be solved without knowing forces directly—but only if you correctly identify all forms of energy at the initial and final states.
Conservation of mechanical energy:
½mv₁² + mgh₁ = ½mv₂² + mgh₂
When friction is present: Work done by friction equals the energy “lost” to heat. W_friction = -f × d (negative because friction opposes motion).
Momentum and Collisions
Momentum is conserved in all collisions (if no external forces). Whether kinetic energy is conserved depends on the collision type:
- Elastic collision: Both momentum AND kinetic energy conserved
- Inelastic collision: Only momentum conserved (KE lost to deformation/heat)
- Perfectly inelastic: Objects stick together (maximum KE loss)
2D collisions require conservation of momentum in both x and y directions separately—which means two equations.
PHY-111L: The Lab Component
PHY-111L is a separate 1-credit co-requisite course with hands-on laboratory experiments. Unlike some GCU science courses that use virtual labs, PHY-111L uses physical equipment—Xplorer GLX data loggers, photogates, projectile launchers, force sensors, and more.
Typical PHY-111L experiments include:
- Lab 1: Measurements — Circumference and diameter relationships, significant figures, uncertainty
- Lab 2: Uniform Linear Motion — Constant velocity motion with battery-powered cars
- Lab 3: Uniformly Accelerated Motion — Carts on inclined tracks, measuring acceleration
- Lab 4: Projectile Motion — Horizontal launches, measuring range vs. height
- Lab 5: Static Equilibrium — Force tables, vector addition of forces
- Lab 6: Newton’s 2nd Law — F=ma relationships with varying masses and forces
- Lab 7: Conservation of Energy — Spring-mass systems, potential and kinetic energy
- Lab 8: Conservation of Momentum — Elastic and inelastic collisions on air tracks
- Lab 9: Circular Motion — Conical pendulum, centripetal force
- Lab 10: Rotational Equilibrium — Lever arms and torque
- Lab 11: Buoyancy — Archimedes’ principle, apparent weight in water
- Lab 12: Ideal Gas Law — Pressure-volume-temperature relationships
- Lab 13: Standing Waves — Waves on a string, frequency and wavelength
What we handle:
- Pre-lab calculations — Predictions and theoretical values before the experiment
