Q: How do I try a free US Common Core US Physics question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live US Common Core Common Core US Physics bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for US Common Core US Physics students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the US Physics questions aligned to the US Common Core Common Core syllabus?

Every question is written against the published US Common Core Common Core US Physics syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real US Common Core past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

What is the law of conservation of momentum?

Accepted Answer

Total momentum before a collision equals total momentum after (in a closed system) — In a closed system with no external forces, total momentum is conserved. This applies to all collisions and explosions.

Answer

Total momentum before a collision equals total momentum after (in a closed system)

Answer

Only kinetic energy is conserved

Answer

Momentum is never conserved

Answer

Momentum always increases
