Force

Force is a pull or push on an object

Force (F) = mass x acceleration due to gravity (g)

          F = mg

The SI unit of force is newton (N)

EXAMPLE

A stone of mass 5kg is suspended from a spring. Calculate the force acting on the stone. [g=10ms-²]

SOLUTION:

Force = mass x acceleration due to gravity

     F= mg
       = 5x10
       = 50N
