Physics comes from the word "Understanding the nature". Everything which is or happening around us is physics. From our walking to revolving of planets, from atom to milky way galaxy, everything is based on it.

Force of 16N and 12N are acting on a mass of 200kg in mutually perpendicular directions. Find the magnitude of the acceleration produced.
Resultant force F= sqrt (16^2+12^2) => F=20N So F=ma => a=F/m=20/200 => a=0.1 ms-2

If force is acting on a moving body perpendicular to the direction of motion, then what will be its effect on the speed and direction of the body?
The magnitude of velocity shall decrease and direction shall be same till it comes to rest, afterwards it shall move in direction of force with acceleration due to the applied force.
