Science Force and Pressure

                   Force and Pressure 

FORCE👉 Force is the effect caused by the interaction of two objects which tries to change the state of the object. The pressure is the force acting on an object in the perpendicular direction to the surface of the object which results in the spreading of force over a certain area.
The unit of the force is newton.
Contact force-(1) Muscular force is a type of contact force ( any force which act after contact ) .
(2) The frictional force is a contact force that acts in the opposite direction to the motion of an object. This force can cause objects in motion to come to rest, as they act in the opposite direction to its motion.

PRESSURE-Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. 
The unit of pressure is Pascal.
FormulaPA=N/m²

Here is his story: In 2017, hear.com’s founder, Dr. Marco Vietor, introduced Piyush Jain to the latest German hearing aid technology: The Horizon. Top German hearing aid engineers (formerly from Siemens) had spent years of Research & Development coming up with a device that has the most advanced technology in a design so small, it disappeared completely behind or inside the ear! When Dr. Vietor asked Piyush Jain to bring this technology to the Indian market, Piyush was hesitant at first: He knew that his own mother had a hearing loss but did not want to wear hearing aids, because she thought that they were too big, looked ugly and would make her look old. To see if Horizon hearing aids were as good as Dr. Vietor claimed, Piyush asked his mother to try one for herself. Not only did she experience an immediate improvement...
