Question

What is $95$ pounds in newtons?

Answer 1

Hint: Pound is a unit of weight and it is the equal to the product of $0.453592 Kg$. When we try to write pounds of force then it is equal to the product of $0.453592 Kg$ and $9.806 ms^{-2}$ ( acceleration due to gravity). Now it is in the S.I. unit of force. But we have to find $95$ pounds so we need to multiply the one pound of force with the $95$.

Complete step-by-step solution:
Force is an external factor able to change the situation of rest or motion of a respective body. It has both magnitude and direction. The direction to which the force acts is known as the force's direction, and the utilization of force is the point where force is applied. The S.I. the unit of force is Newton.
$F = ma$
$1 N = (1 Kg ) ( 1 m s^{-2})$
One kilogram force is the one-kilogram weight under standard gravity. It is equal to the magnitude of the force that is acted on one kilogram mass in a gravitational field of $9.806 ms^{-2}$. Pound is the unit of weight and $1$ pound is equal to the $0.453592 Kg$.
We have $95$ pounds, we need to convert it into kilograms.
$95 pounds = 95 \times 0.453592 = 43.09124 Kg $
We convert $43.09124$ Kg of weight into Kg of force.
$95 pounds = 43.09124 \times 9.806 = 422.552 N $
So, $95$ pounds are equal to $422.552$ in newtons.
Additional Information: - Kilogram is the unit of mass and newton is the unit of force. Pound is used for both mass and weight: Pounds-Mass and Pounds-Force. Mass remains constant but weight changes with the gravitational field. One Pound force is the gravitational pull felt by a body of one pound mass.

Note: A pound-force is not the SI unit of force or weight. The pound-force is equivalent to the product of the one-pound mass by the acceleration due to gravity on Earth. One-Pound force is the gravitational force acting on a mass of one pound under the standard gravity condition.
