As per your syllabus, what is RECTILINEAR motion?

  1. Motion in a plane
  2. Motion in a curved path
  3. Motion of objects along a STRAIGHT LINE — the focus of Chapter 2
  4. Circular motion only
Show answer and solution

Correct answer: C. Motion of objects along a STRAIGHT LINE — the focus of Chapter 2

As per your syllabus, rectilinear = straight-line motion. Other motion types covered in later chapters.

As per your syllabus, what is INSTANTANEOUS acceleration?

  1. Half the average acceleration
  2. The limit of average acceleration as Δt → 0: a = dv/dt
  3. Always zero
  4. Final velocity divided by total time
Show answer and solution

Correct answer: B. The limit of average acceleration as Δt → 0: a = dv/dt

As per your syllabus, Eq 2.3, a = lim(Δt→0) Δv/Δt = dv/dt. Analogous to instantaneous velocity.

As per your syllabus, the magnitude of ACCELERATION DUE TO GRAVITY (g) near the Earth's surface is approximately what value?

  1. 9.8 m/s
  2. 0.98 m/s²
  3. 9.8 m/s²
  4. 98 m/s²
Show answer and solution

Correct answer: C. 9.8 m/s²

As per your syllabus, g ≈ 9.8 m/s². The unit is acceleration (m/s²), not velocity.
