When will the game start?? I've been waiting for a while now...what homework did we have for science...Newton's Laws, right?
During a soccer practice...
Let's see...according to Newton's first law, an object will remain at rest until a force acts upon it, like this ball. It's staying still because no one is moving it.
This ball weighs 420 grams. So according to the second law. This player is getting ready to kicking it at, hmm, let's say at 6 m/s, which would be the acceleration. Using the formula, the force needed will be is 420*6 = 2520 in order to be a good kick.
You know what...I think my calculation was incorrect, but you get the gist of it, hopefully. Anyways, according to Newton's third law of motion, for every action, there is an equal and opposite reaction! So when she kicked the ball, the ball is actually pushing back at her foot too.
