As per your syllabus, Ex 1.4, which formula for kinetic energy is dimensionally INCORRECT?
AK = (1/2)mv²
BK = m²v⁴/2 (dimensionally)
CK = (3/16)mv²
DK = ma
Answer & Solution
Correct answer: D. K = ma
syllabus Ex 1.4: K = ma has dimensions [M L T⁻²] (force-like), not [M L² T⁻²] like energy. Wrong dimensionally.
