physics in our daily life

Many people assume that just Physical science which only naturalize without any implementation. Mainly there are still many people who think that the only study physics formulas. And not a few who do not realize that many of the events even things that are very close to us involves the science of Physics. Even Physics is the basic science that is needed by the other branches of sciences. Why Physics is very important in our lives?
Of course as many of the events in our lives that involve science Physics whether we realize it or without us knowing.

Look at the picture !



Two students were carrying the chair. Only push and pull them. Working together they cause the seat can be moved easily. Similarly, the force required to kick the ball so that the ball right up to the specified target.

Pull or push in physics called the force. Thus, the work force on an object is synonymous with pushing or pulling objects.

Two Kinds of Force :
There are two types of Force, the style of touch and Force not touch.
1. Force touch
Touch Force is a force that arise due to direct physical contiguity between two objects.
Examples of touch force: friction, normal force, the spring force, muscle force and the like.




2. Force does not touch
Do not touch force is a force that does not arise even if the two objects rub together physically.
Examples of force not touch: the gravitational force, magnetic and electric force.






and, the formula the force is :




  • F : force (N)
  • m : mass (kg atau g)
  • a : acceleration (m/s2 atau cm/s2)

if the mass is increase, so the force is increase too and the greater the force applied the greater the acceleration experienced by the object.
