Question

An 80 N force causes a spring to compress 0.15 m. What is the spring constant? What is the potential energy of the spring?

Answer 1

The spring constant of the given spring is= -533.33

The potential energy of the spring= 6 Joule

What is force?

A push or pull that causes object to change its state of rest or motion.

• It can also change the direction of a moving body.
• Force is a product of mass and acceleration.

For spring;

K is the spring constant.

         ⇒Force = -kx

         ⇒80N=0.15m ×-k

          ⇒K=-80/0.15

          ⇒K= -533.333

So the spring constant is 533.333

Potential Energy=1/2kx²

                            ⇒0.5×533.33 ×0.15×0.15

                            ⇒5.95.99 N
