Aim: To determine the spring constant(k).
Introduction: Force applied on a spring to elongate it. The weights of the masses are the forces on the spring.
Applied force=WEIGHT
Weight is the gravitational force on the objects.
Weight is equal to mass times gravity acceleration.
W=m.g
Weight(W) has a unit of N
Mass(m) has a unit of kg.
Gravity acceleration(g) has a unit of kgms-2.
The extension of the spring is measured by initial and final length of the spring.
Extension=final length – initial length
Extension(e) has a unit of cm.
