The mass is just sitting there motionless. There is no acceleration and it is in equilibrium. What does this mean? This means that the net force in the y-direction (vertical direction) must be zero. I ...

Here is a spring mounted vertically. Also, there is a hanger for some masses on the end. Now suppose I measure the location of the bottom of the mass holder. Then I place a 250 gram mass in the holder ...

The elastic potential energy stored can be calculated using the equation: A spring has a spring constant, k, of 3 N/m. It is stretched until it is extended by 50 cm. Calculate the elastic potential ...
