Question
1)A spring can exert what kind of forces if all different sizes. How can it be said to have a spring constant, also called a stiffness constant or force or k value or Hookes-law constant? 2) what sort of object has kinetic energy? That is, in what situation must the object be, to possess nonzero kinetic energy?Please help me answer the follow two questions, thank you! (I will give a good rating) 1)A spring can exert what kind of forces if all different sizes.

Explanation / Answer
1) Springs exert spring contact force, which is a push force due to the compressed condition of the spring.
It has a stiffness or spring constant which is a measure of the stiffness of the spring. More the spring constant, more is the stiffness.
2) An object in motion has kinetic energy. KE is proportional to the square of the velocity, thus the object must have a velocity, i.e. it must be in motion to have a nonzero KE.
