Question

What are the units for the spring constant, k? A. newton meters B. newton seconds C. newtons/meter D. newtons/second E. newtons/seconds2

Answer 1

C. N/m (newtons/meter)

Step-by-step explanation:

Since the equation for potential energy for a spring is PE = 1/2kx², after you know k and x, you will get an answer in Joules.

Please let me know if you want me to explain further!

Thanks!

Answer 2

Option (c)

Step-by-step explanation:

The spring constant is defined as the force per unit length of compression or expansion in spring. So it's unit is newton per metre.
