Mechanics topic test

Use vectors, trajectories, circular motion, turning effects, momentum, and collisions to read motion and interactions on one compact simulation-first branch.

What this run covers

This first-pass topic test reuses the shared quiz engine, but it balances question selection across the included concepts so the topic is assessed as a broader branch instead of a single concept replay.

Review the concepts behind this topic test

Every topic test still points back to the published topic page and the included concept pages, so you can review the exact learning surfaces behind the questions.

Physics

Vectors and Components

Rotate and scale a live vector, decompose it into horizontal and vertical parts, and watch those components drive the same straight-line motion and geometry.

Open Vectors and Components Open concept test

Physics

Projectile Motion

Launch a projectile, watch the trajectory form, and connect the range, height, and component motion to the launch settings.

Open Projectile Motion Open concept test

Physics

Uniform Circular Motion

Track a particle moving at constant speed around a circle and connect radius, angular speed, tangential speed, centripetal acceleration, and the inward-force requirement to the same live state.

Open Uniform Circular Motion Open concept test

Physics

Torque

Push on one pivoted bar and see how lever arm distance, force direction, and turning effect stay tied to the same compact rotational bench.

Open Torque Open concept test

Physics

Static Equilibrium / Centre of Mass

Shift one support region under one loaded plank and see how centre of mass, support reactions, and torque balance decide whether the object stays stable or tips.

Open Static Equilibrium / Centre of Mass Open concept test

Physics

Rotational Inertia / Moment of Inertia

Keep the same total mass and torque, then slide equal masses inward or outward to see why moment of inertia makes some rotors much harder to spin up than others.

Open Rotational Inertia / Moment of Inertia Open concept test

Physics

Rolling Motion

Roll a sphere, cylinder, hoop, or custom mass distribution down one incline and see how rolling without slipping ties translation, rotation, and rotational inertia to the same honest run.

Open Rolling Motion Open concept test

Physics

Angular Momentum

Treat angular momentum as rotational momentum on one compact rotor where mass radius and spin rate stay tied to the same readouts, response maps, and same-L conservation story.

Open Angular Momentum Open concept test

Physics

Momentum and Impulse

Push one cart with a timed force pulse and watch momentum, impulse, and force-time area stay tied to the same motion, readouts, and graphs.

Open Momentum and Impulse Open concept test

Physics

Conservation of Momentum

Watch two carts trade momentum through one bounded internal interaction and see the total stay fixed while the individual momenta, velocities, and center-of-mass motion update together.

Open Conservation of Momentum Open concept test

Physics

Collisions

Collide two carts on one honest track, keep total momentum in view, and see how elasticity, mass, and incoming speed shape the rebound or stick-together outcome.
