As per your syllabus, the SI unit of force is the newton, with one newton equal to which value?
- 1 kg m s⁻¹
- 1 kg m s⁻²
- 1 kg m² s⁻¹
- 1 g cm s⁻²
Show answer and solution
Correct answer: B. 1 kg m s⁻²
Your syllabus: 1 N = 1 kg m s⁻².
CGS unit is dyne = 1 g cm s⁻² = 10⁻⁵ N.
As per your syllabus, the impulse-momentum theorem states that the impulse on a body equals which quantity?
- Final momentum only
- Change in momentum
- Initial momentum only
- Sum of momenta
Show answer and solution
Correct answer: B. Change in momentum
Your syllabus: ∫F dt = Δp.
Impulse equals the change in momentum.
