How using physic’s helps the optimization of everyday life activities?

Ricardo J. Ares Juliá

There are many concepts of physics that people that haven’t taken any course of physics know but if they learn more about physics they would optimized the way they achieve their everyday life shores. For example themes like vector sum, inclines, potential energy, projectile motion and friction. The ways people can use physics in their lives are innumerable because physics is used to explain phenomenon’s that occurs trough the course of everyday. Just by stopping a moment and analyzing what it is happening people could figure out how to do some works in a more efficient way. This is what Newton did to develop all of his theories and law’s that helps humanity so much; he just waited, observes and analyzed what was happening.

With out going to deep into physics, how could some one be more efficient when passing a land mower on a patio? There are many conditions that can and will have an effect when dealing with this type of work but having two basics scenarios, the most efficient way to applied force trough a displacement on the land mower in a horizontal plane is to pull it because in this way the weight of the machine is reduce due to the force being applied to the handle that’s has an angle of inclination and it is easier to cut the grass faster. But when having and incline surface it is better to push down the incline plane the land mower due to most of the force exerted in the machine will be applied by gravity when going down and only a small force will be applied from the person to stop the machine from keep on going downhill. As when going up hill it is easier to pull, for the same reason’s when dealing with the land mower in a flat surface. Recently there have been many sports championships in the past year and most of these sports involve playing with balls and most of the efficient way to optimize the launch of the projectile (ball) is to have a good angle when dealing with an approximate constant force. For example a football quarterback that wants the most of his launch is to have a 45 degree angle from the horizontal at the point in which the ball was thrown but for a baseball pitcher is not how big it gets its angle of pitching but how fast he throws the ball and the batter needs the combination of the angle in which he hits the ball with how much normal force is applied from the baseball bat to the ball. In other words the normal force is a force with the same magnitude as the one applied by the ball but including and opposite direction to the one that travels by the ball. 

This examples of everyday life helps us to understand better how and why matter behaves the way it does. It could be ideal to teach every person the basics of physics to ensure the optimization when dealing with everyday situation, for instance how to just to past a land mower more efficiently.
