Hi.
First post here and not a native english speaker, so be kind :-)
1) I have never really understood what it means when we say that the gravitation accelerations is 9,82 m/s2
What is the practical use. Could anyone tell me with a simple example. I think the confusing part is the s2.
2) I have seen an experiment relating to one of newtons laws which consitet of a wagon moving down a hill. At some point a spring on the wagon was released which made the ball flying and landing in the wagon (which had already moved). Does this experiment have a name?
Thanks in advance. I hope you can help :-)
