Force in terms of base units is expressed as:
Correct answer: A. Kg ms-2
- A. Kg ms-2
- B. Kgm2s-2
- C. Kgm2s-3
- D. None of these
Explanation
According to Newton's 2nd lawF=maWhere F is force , m is mass and a is acceleration . The unit of mass is 'kg' and the unit of acceleration is 'm/s2' .The units of F will be,F=kgm/s2F=kgms-2

About Physical Quantities and Units
Physical quantities combine a numerical value with a unit, and are expressed using SI base units or derived units such as newtons, joules and pascals. The topic covers prefixes, unit conversion, dimensional analysis, significant figures and measurement uncertainty, while distinguishing scalar quantities from vectors where direction matters.
