How many questions are in this quiz?

This quiz has 106 questions covering momentum, impulse, and collisions in 1D and 2D.

No. There’s no timer, so you can take your time with diagrams, components, and algebra.

What answer format does each question use?

Each question is multiple-choice with 4 options.

Does it include both elastic and inelastic collisions?

Yes. You’ll see elastic, perfectly inelastic, and general inelastic cases, including when to check kinetic energy.

How do I choose the number of questions and difficulty?

Before starting, pick how many questions you want to attempt and adjust difficulty to match your practice goal.

About this quiz

What this quiz covers

Momentum problems get tricky fast once directions, angles, and multiple objects appear. This quiz moves from straight-line collisions to 2D interactions where vectors and components matter.

Each question has 4 options and there’s no timer, so you can focus on setting up the physics cleanly rather than rushing.

Skills you’ll practice

You’ll practice choosing the right conservation laws, translating words into diagrams, and keeping track of vector components in 2D. Mixed difficulty is balanced by blending quick concept checks with longer multi-step calculations.

Applying conservation of momentum in 1D and 2D
Distinguishing elastic vs inelastic collisions and using kinetic energy checks
Using impulse and force–time graphs to find momentum change
Working with center-of-mass velocity and relative motion ideas
Resolving vectors into x/y components and tracking signs consistently

Common pitfalls (and how to avoid them)

Many wrong answers come from assuming kinetic energy is always conserved, mixing up “sticks together” with “bounces,” or forgetting that momentum is a vector. In 2D, the most frequent slip is skipping a component equation or using angles from the wrong reference axis.

Choosing length and difficulty

You can set your question count before starting for a quick warm-up or a full practice session. Difficulty is mixed by default, and you can adjust it to focus on fundamentals first or include more multi-step 2D collision scenarios as you improve.
