AP Physics 1
Turn forces, motion, energy, and fluids into ideas you can explain.
Study calculus-based mechanics through clear explanations, labeled models, worked examples and original practice. Units 1–4 cover Kinematics, Force and Translational Dynamics, Work, Energy, and Power, and Linear Momentum.

Begin with arrows and everyday motion. Build toward derivatives, integrals, relative motion and projectiles. 32 original questions, 48 recall cards and 16 written challenges. Every lesson follows Learn → Explore → Practice → Review. Teacher review and student testing remain pending.
Choose a system, identify interactions, and connect forces to motion. Explore center of mass, friction, springs, gravity, drag and circular motion. 44 original questions, 66 recall cards and 22 written challenges support Learn → Explore → Practice → Review. Independent teacher review and student testing remain pending.
Follow energy as forces act: compare kinetic energy, integrate work, read potential-energy curves, choose system boundaries, and calculate power. 36 original questions, 54 recall cards and 18 written challenges support Learn → Explore → Practice → Review. Independent teacher review and student testing remain pending.
Follow momentum through pushes, rebounds, separations and collisions. Interpret force–time areas, choose a system, track its center of mass, and check what happens to kinetic energy. 30 original questions, 45 recall cards and 15 written challenges support Learn → Explore → Practice → Review. Independent teacher review and student testing remain pending.

Calculus bridge: learn what a derivative and a definite integral mean before applying them. Use g = 10 m/s² for the idealized near-Earth examples. Official College Board framework. Focused lesson titles and original questions are Refresh Kid’s organization. This is a review edition; independent teacher review and student testing remain pending.

Try our interactive learning lab →Strengthen the calculus behind the physics, then practice showing a complete chain of reasoning.
You can bring schoolwork, a recent assessment, or the topic that is slowing you down. Your teacher can use that starting point to identify gaps and agree on a manageable plan.
A tutoring overview, not a complete course syllabus. Session content is matched to your schoolwork, level and goals.

Have your course name, syllabus or current topic, a recent assignment, and preferred meeting times ready. For exam preparation, include your test date and a recent practice result if you have one.
Yes. Share the syllabus, assignment instructions and upcoming assessments so the teacher can discuss an appropriate plan. Tutoring supports learning; it does not replace your school’s enrollment or assessment rules.
Tell us the exact course, grade, and timezone. Ask about the teacher’s recent experience with that subject, their approach, and available meeting times.
No. Progress depends on starting skills, practice, attendance, course demands and other factors. The plan should focus on specific skills and review progress honestly.
Turn forces, motion, energy, and fluids into ideas you can explain.
Make sense of electricity, thermodynamics, waves, and modern physics.
Build confidence with fields, circuits, and calculus-based reasoning.
