What is Force?

[Admin]

One object exerts on another characterizes an interaction between the two objects called as Force. The force causes some effect or influence on the one object on the second object. Forces are represented by a symbol with an arrow above it to show that the force has a direction and with two subscripts indicating the two objects. For example, if the earth pulls on a ball, we note the force exerted by the earth on that ball as F Earth on Ball
Force is a physical quantity that is measured in units of Newtons (N).
