1
New cards

Hooke’s Law

T = kx

2
New cards

tension equation

T = λx / l

3
New cards

if a particle is having in equilibrium…

the tension will be equal to the weight of the particle

4
New cards

how to use Hooke’s law in dynamic problems

find the value of F, the resultant force, and then equate this to ma

5
New cards

maximum speed is when

acceleration is 0

6
New cards

elastic energy, or work done to stretch a spring

λx² / 2l (only applies when within the elastic limit of the spring)

7
New cards

conservation of energy for springs and strings

(driving force •distance) + initial KE + initial GPE + initial EPE = (friction •distance) + final KE + final GPE + final EPE
