Five-minute GRE Physics concept check

Try three original public mechanics questions and receive a device-local concept-oriented result.

1. A 2 kg cart has 10 N applied right and 4 N friction left. What is its acceleration?

3 m/s² right5 m/s² right7 m/s² right

2. An object moves at constant velocity in a straight line. What must be true of its net force?

It points forwardIt is zeroIt equals the object's weight

3. The same net force acts separately on masses m and 2m. How do their acceleration magnitudes compare?

The 2m mass accelerates twice as muchThey are equalThe m mass accelerates twice as much

Method and limitations

Method version: public-mini-check-v1. Inputs and results stay in this browser page; analytics receive the page view, not the values you enter or answers you select.

The three questions are original public records in the page bundle and have no protected-bank UUID.
Each checks one Newton's-second-law relationship and returns an authored explanation after all responses are selected.
The result stays in the browser and is not written to practice attempts, learner evidence, analytics, or a profile.
Three public items cannot diagnose mastery, forecast a score, or represent the full exam blueprint.
