Worked practice questions

As per your syllabus, Aristotle's fallacy held that a force is required for which condition?

  1. To accelerate a body
  2. To stop a moving body
  3. To change a body's direction
  4. To keep a body in uniform motion
Show answer and solution

Correct answer: D. To keep a body in uniform motion

Your syllabus: Aristotle wrongly assumed motion needs force to maintain it. Galileo + Newton corrected this — only ACCELERATION needs force.

As per your syllabus, a ball released on a frictionless incline rises on the other side to which height?

  1. Zero height (rolls flat)
  2. Always higher than initial
  3. Same as initial height
  4. Always lower than initial
Show answer and solution

Correct answer: C. Same as initial height

Your syllabus: in the ideal frictionless case the ball regains its initial height regardless of the slope of the second incline.

As per your syllabus, INERTIA of a body is best described as which property?

  1. Speed achieved at rest
  2. Force of gravity acting on it
  3. Resistance to change in state of motion
  4. Tendency to accelerate when free
Show answer and solution

Correct answer: C. Resistance to change in state of motion

Your syllabus: inertia = resistance to change. A body at rest stays at rest a body in uniform motion continues uniformly.
