1.Introduction
Force is vector. So, we can estimate force adds. How do we get this? These experiments will help us know to measure forces and add them. In progress, we will understand hook’s law.

2.Theory
Here is some theory related experiments.
1)Addition Vector
Vector is physical magnitude has direction and quantity. Typically, velocity, force, acceleration is vector. Addition vector requires especially mathematical method. Because considering direction. Usually, we use parallelogram method to add vector.
(Figure a)
As upside figure, connect each vector’s head and tail, and draw displacement. It is addition vector A and B.
2)Newton’s second law. (F=ma)
This law provides relation force, mass and acceleration. The net force on an object is equal to the product of the object’s mass and its acceleration. At, net force is all force’s addition affecting on object.
3)Hook’s law
As elastic gum or spring is transformed by external force, internal force occurs. Internal force equal to the product the length transformed and modulus of elasticity.
Modulus of elasticity is characteristic value in each object.
