what are the formulas for this test (H2 + H5 §1 and 2)?

W=m⋅g

Mass and weight

Mass: the amount of matter in an object – unit: kg (kilogram).

Weight: the force gravity exerts on an object – unit: N (newton).

The elastic limit

The length of extension after wich the spring won't go back to it's original lenght.

The formulas

ρ=​V​​m​​

F=k⋅x

F=m⋅a

P=​A​​F​​
