Question

What are the units for the spring constant,k?

Answer 1

Answer:

The units for the spring constant k is $\frac{kg}{s^2}\ \text{or}\ \frac{N}{m}$.

Explanation:

According to hooks law:

$F=-kx$

Where F is a force, k is spring constant and x is distance.

Here, the negative sign of the force of the spring, which implies the force of the spring, is opposed to the displacement of the spring.

Now in order to find the units for spring constant k, ignore the negative sign as we are looking only at the magnitude.

$F=kx$

$\frac{F}{x}=k$

Therefore,

$\frac{kg}{s^2}\ \text{or}\ \frac{N}{m}$

Hence, the units for the spring constant k is $\frac{kg}{s^2}\ \text{or}\ \frac{N}{m}$.

Answer 2

Answer:

$\frac{kg}{s^2}$ or $\frac{N}{m}$

Explanation:

The force in a spring is described as (F) = (k) x (d) with (d) being the displacement, measured in meters. (F) is to come out in Newtons. So (k) is assigned the appropriate unit for that to happen. The two possibilities listed above achieve that.
