What’s the objects ? Just reply to this comment
S=d/t this is because speed is just the measurement of time and distance
Gravity..? I don't know, but you need to clear up your question a bit. I'm sure it's gravity though.
Answer:
Spring constant = YA / L
Explanation:
Let F be the force being applied on cross sectional area A of metal bar due to which an extension of ΔL is obtained in the wire of length L then
stress = F / A
strain = ΔL /L
Young's modulus = ( F / A ) / (ΔL /L)
Y = ( F L / A ΔL )
( F / ΔL ) = ( YA / L )
Spring constant = ( F / ΔL )
Spring constant = YA / L
