View current plans in MemoriziteFor an object of constant mass observed in an inertial reference frame, the resultant force equals mass multiplied by acceleration. A resultant force of 6 N acting on an object of mass 2 kg gives an acceleration of 3 m/s² in the direction of that force. If the resultant force is zero, acceleration is zero; the object can still have a constant nonzero velocity. With the same nonzero resultant force, doubling the mass halves the acceleration. Resultant force means the vector sum of the external forces, not necessarily the force from one individual interaction.

Four-option calculation
B. 3 m/s².
Acceleration = resultant force ÷ mass = 6 ÷ 2. Keep the unit and the stated model conditions.
A qualified conclusion
C. Velocity can remain constant and nonzero.
Zero resultant force implies zero acceleration. It does not imply that the object must be at rest.
A relationship
A. It halves.
In a = F/m, holding F fixed and doubling m divides acceleration by two.
Retain units, model assumptions and the sentence around a formula. A two-column handout can extract in an unexpected reading order; check that a condition has not become attached to the wrong equation. Export lecture slides to a readable PDF if your source is a slide deck. The upload interface does not accept PowerPoint files directly.
Answer before looking back at the passage. Then explain why one option fits and each alternative fails. The worked example distinguishes acceleration from force and rest from constant velocity; a plausible-looking number is not enough. Generated options can be ambiguous or contain mistakes, so the PDF remains the reference.
Sign in, select Games and upload the PDF. In the resulting study view, use Choice if that format has questions. There is no pre-upload MCQ-only generator switch, and the output is not guaranteed to contain a particular number of MCQs or four choices in every case. If no Choice activity is available, use an available format or another suitable source.
Upload a PDF, TXT or Markdown file up to 10 MB. A scan or image-heavy page may be difficult to read, and extraction can fail. Save other material in a supported file first: this workflow does not directly import Word, PowerPoint, URLs or pasted text, or add a subject-specific generator setting.
Before studying, check the answers in your original document and look for missing topics. Generated cards and questions can be wrong or unclear. Their number and available formats may differ from these examples, and your usual account and plan limits still apply.
In Choice, select an option and press Lock it in! The result shows your response and, when you miss it, the correct answer. A generated explanation and source context are shown when present. Compare them with the original PDF; feedback is not proof that the generated answer is correct.
