Understanding Hooke's Law

What is the formula for Hooke's Law, and what does each symbol in the formula represent?

If a spring has a force constant (k) of 250 N/m, how much force is required to stretch it by 0.2 meters?

A spring is stretched by 5 cm and the force applied is 10 N. Calculate the spring constant.

If a spring with a force constant of 150 N/m is compressed by 3 cm, what is the restoring force exerted by the spring?

How much energy is stored in a spring with a force constant of 400 N/m when it is stretched by 10 cm?

If a force of 20 N stretches a spring by 4 cm, what is the spring constant and how much work is done in stretching the spring?

A spring is observed to have a spring constant of 100 N/m. If the spring is initially at its equilibrium position, how much will it stretch when a 5 N weight is hung from it?

Describe the relationship between the extension of a spring and the force applied according to Hooke's Law.

If the force constant of a spring is doubled, what will be the new force required to stretch the spring by the same amount as before?

A spring with a force constant of 300 N/m is stretched by an unknown distance, and the force measured is 60 N. Calculate the distance the spring was stretched.
