A: A stiffer or stronger spring means a greater force in Newton’s second law, F = ma. For a given mass, that means a greater acceleration so the mass will move faster and, therefore, complete its motion quicker or in a shorter period.

How does mass affect the stretch of a spring?

A: A stiffer or stronger spring means a greater force in Newton’s second law, F = ma. For a given mass, that means a greater acceleration so the mass will move faster and, therefore, complete its motion quicker or in a shorter period.

Why does a spring stretch?

A typical spring is a tightly wound coil or spiral of metal that stretches when you pull it (apply a force) and goes back to its original shape when you let it go again (remove the force). In other words, a spring is elastic. … Some alloys have a property called shape-memory, which means they’re naturally springy.
