Fđh = K/delta L+x/
delta L, x phải đổi ra đơn vị thuần
Lực đàn hồi cực đại: Fđhmax = k(delta L +A)
Lực đàn hồi cực tiểu
+ Nếu A>= delta L -> Fđhmin = 0 <-> x = -delta L
+Nếu A< delta L -> Fđhmin = K(delta L - A) <-> x = -A
Con lắc lò xo nằm ngang: delta L = 0 -> Fđh = k/x/ = Fhp
-> Lực đàn hồi chính là lực hồi phục
Công thức dạng tổng quát của lực đàn hồi:
+ Nếu chọn chiều (+) cùng chiều biến dạng an đầu: Fđh = /delta L + x/
+ Nếu chọn chiều (+) ngược chiều biến dạng ban đầu: Fđh = /delta L -x/
Lực đàn hồi tác dụng lên vật chính là lực đàn hồi tác dụng lên giá treo
