Question

example of force with daigram Science class 8.​

Answer 1

Answer:

Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area. The basic formula for pressure is F/A (Force per unit area). Unit of pressure is Pascals (Pa). Types of Pressures are Absolute, Atmospheric, Differential, and Gauge Pressure. While sipping beverages from a straw, have you noticed that you actually suck the air out of the straw? While you sip the beverage, you’re actually applying ‘Pressure’.

Pressure (P) = Thrust/ Area

Explanation:It is easier to hammer a sharp pin than to hammer a blunt pin. This is because the area at the end of the sharp pin is smaller than the area at the end of a blunt pin. This leads to an increase in pressure leading to hammer the sharp pin easily.

Answer 2

Explanation:

❥Force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.

❥When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction
