que é uma deformação (em física) e o que ela nos fornece?

3)
Explique o que é força elástica e qual sua equação.

4) Qual
a diferença entre dinamômetro e balança?

5) O
que é equilíbrio estático?

6) O
que é Centro de Gravidade?

7) Como
determinar o Centro de Gravidade de um objeto?
8) Em que situação um corpo fica em equilíbrio
estático?
