The term rectilinear acceleration means the rate of increase of
A
velocity along a circular path in a unit time
B
distance along a rectangular path in a unit time
C
displacement along a straight-line path in a unit time
D
velocity along a straight-line path in a unit time
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Rectilinear acceleration refers to the acceleration experienced by an object moving in a straight line (rectilinear motion). Acceleration is defined as the rate of change of velocity with respect to time, which aligns with the rate of increase of velocity along a straight-line path.
