A motionless mass, hung on the end of a spring and pulled 5 cm downward, is a height of 1 meter above the classroom floor. Is that potential, kinetic, or elastic energy ?
Answers: 3
![E_{elas}=0.5*k*x^2\\where:\\k = spring constant [N/m]\\x = distance [m]\\\\E_{pot} =m*g*h\\where:\\m = mass [kg]\\g = gravity = 9.81[m/s^2]\\h = elevation [m]\\\\E_{k}=0.5*m*v^2\\where:\\m= mass [kg]\\v = velocity [m/s]](/tpl/images/0562/8969/95ae4.png)
