the force applied to the spring is equal to its elongation

Hooke's Law ceases to be valid

the spring is can be stretched but still springs back into shape reversibly

the spring constant increases

area under the curve

read the y-axis

read the x-axis

slope

the net force is 4N

the spring is 0.4m long

the stored potential energy in this spring is 1.6 J

the spring constant is 10 N/m

both experience the same maximum force

both experience the same elongation

both store the same amount of elastic potential energy

both have identical spring constants

A has a larger spring constant than B so A is a stiffer spring

B has a larger spring constant than A so A is a stiffer spring

A has a larger spring constant than B so B is a stiffer spring

B has a larger spring constant than A so B is a stiffer spring
