Answer: [MLT⁻²].
- A [MLT⁻²]
- B [ML²T⁻²]
- C [MLT⁻¹]
- D [ML⁻¹T⁻²]
Correct answer: A. [MLT⁻²]
Explanation: Force = mass × acceleration = [M][LT⁻²] = [MLT⁻²].
The 7 SI base units. All derived units (newton, joule, watt, volt, etc.) can be expressed as combinations of these 7 fundamental units raised to various powers.
Concept context
SI base units, dimensional analysis, significant figures, and error propagation. The toolkit every physics calculation relies on.
