♥ Force and Pressure
A force is a push or a pull.
A force change the shape of an object, change the size of an object, make a stationary move, stop a moving object, speed up or slow down a moving object, change the direction of the moving object.
The measure of the amount of force acting on a unit area is known as Pressure.
Formula for calculating pressure: Pressure = Force ÷ Area (pascal) (Newton) (square metre)
[ pa ] [N] [m²]
If the area increases, the force is constant, the pressure will decrease. If the area decreases, the force is constant, the pressure will increase.
