Q1. what is force and pressure
Answers
Answer:
Pressure is a measure of how much force is acting upon an area. Pressure can be found using the equation pressure = force / area. Therefore, a force acting over a smaller area will create more pressure.
When an object is either pushed or a pulled is known as a force.
he state of ‘rest’ of an object is considered to be the zero speed, as −
An object cannot move by itself.
An object cannot change its speed by itself.
An object cannot change its direction by itself.
An object cannot change by itself.
A force may make an object move from rest.
A force may change the speed of a moving object.
A force may change the direction of a moving object.
A force may change the shape of an object.
The force, applied on a unit area of a surface is known as pressure Pressure=force/area on which it acts.
If the area is smaller, then the pressure on a surface would be greater; e.g. this is the reason that the area of one end of a nail is pointed to exert sufficient pressure and other end is bigger.
