Question

Slug is a unit of

• A. weight
• B. mass
• C. length
• D. area

Answer 1

The correct option is B

mass

The explanation for the correct option:

From Newtons's second law of motion, we know that,

$\mathrm{F}=ma$

Where $\mathrm{F}$ is the force applied, $m$ is the mass of the object and $a$ is the acceleration gained by the object.

Thus, we can define mass as the force required per unit acceleration of the object.

1. In the C.G.S system of units, the unit of acceleration is feet per square seconds ($\mathrm{ft}/{\mathrm{s}}^2$) and the unit of force is pound ($\mathrm{lbf}$).
2. In the C.G.S system, the unit of mass is slug which is defined as the mass which accelerates by $1\mathrm{ft}/{\mathrm{s}}^2$ when $1\mathrm{lbf}$ of force is applied.
3. It is equal to $14.59\mathrm{kg}$

Hence, option B is correct.
