Match it! Select the correct answer from the pull down...Good luck!

When a body is suspended to the hook of a spring then it is under the effect of:

The curve Characterizes the variation of T as a function of ∆l:

principal of interaction acts on:

The unit of a force is

Weight is a force of gravity and its type

Hook’s law states:

T = K ∆l is Hook’s law where K is:

At equilibrium the two forces acting on a body rests on a smooth table:
