Power/Work/Force

This week in physics we learned about force, power, and work. We learned that work is equal to force multiplied by distance. So W = fd. This means that the farther you go, the more work you do. Force is equal to mass*acceleration. Then there is power. Power is equal to work divided by time.
These are all related in some ways.  In the picture above, you can see the route the receiver ran. If his acceleration was 2m/a and he has a mass of 89kg then his force, 98kg(2m/s) is 196N. Now that we have the force we can find the work. Work is just force(distance). If the receiver ran 25m then the work would be  w= 196(25) = 4,900 J.  Now with the work we can find power with work divided by time. So it could be 4,900/4 which is 1,225 W. And that's how we find power

What I Am Thankful For In Physics

So far this year in physics we learned about things like momentum, motion, and vectors.  But the thing I am most thankful for is Newton's first law.  An object in motion tends to stay in motion unless acted upon by an unbalanced outside force.  The reason why I like this is because it can apply to sports.  For example in baseball and football when the ball is hit by either a football or by a bat, force is applied to it causing it to accelerate.   If there wasn't an unbalanced and outside force called gravity the ball would keep flying and flying.  But because of gravity the ball falls.
