• The unit of force is named after the english scientist Sir Isaac Newton
• One newton is defined as the force required to move an object with a mass of one kilogram in the direction of force at a speed of one metre per second
• The force of attraction exerted on a body by earth is called weight of the body or the force of gravity acting on a body
• The force of gravity on a body of mass 1kg is 1kgf or 10N (9.8N)
• one pascal is equal to one newton per square meter
• The unit of force kgf and N are related as 1kgf= 10N
