Question

Define force and pressure.

Answer 1

A 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.
The SI unit of force is Newton(N)
F=ma
The net force equals the mass of the object multiplied by the amount of acceleration.
What is pressure?
- Definde as the force per unit area.
- Force is measured in newtons (N), area is measured in square metres $\left(m^2\right)$
- Pressure is measured in pascals (Pa), where 1 Pa is equivalent to $\frac{1N}{m^2}$.

$Pressure=\frac{Force}{Area}$
