Interactive Stimulation on Masses & Springs
https://phet.colorado.edu/en/simulation/mass-spring-lab 
Today, we learnt about elastic spring force using the above interactive stimulation. These were the observations made in our discussion:

1. The more friction there is in the spring, the less elastic the spring will be / the faster the spring will come to a stop.
2. The harder Spring 3 is, the less elastic the spring will be / the faster the spring comes to a stop.
3. The heavier the weight on the spring, the longer the spring will be extended.
4. The greater the elastic spring force exerted when we release the weight, the greater the heat produce in the form of Thermal Energy.
