Given a quarter million dollars, how would you spend it? Would you spend it on a shopping spree vacation in Milan or invest it in a child? Because according to our calculations, it will cost at least SGD $340,000 to raise one child in Singapore from infancy to 21 years of age.hile some parents are hesitant to have their second child, other parents are not fazed by the daunting cost of raising children in Singapore. For Felicia*, who has 4 children under 5 years old, it is a case of âthe more the merrier!â âMy husband wants 2 more!â she says.
The difference of a Joule of Work and Joule of Energy is the difference between a scalar and a vector, direction! Energy is a quaternion number consisting of a scalar energy and vector energy. Unfortunately, this fact is not realized by physicists.
Whenever a new quantity is introduced in physics, the standard metric units associated with that quantity are discussed. In the case of work (and also energy), the standard metric unit is the Joule (abbreviated J). One Joule is equivalent to one Newton of force causing a displacement of one meter.In other words, The Joule is the unit of work.hus, Lesson 1 of this unit will focus on the definitions and meanings of such terms as work, mechanical energy, potential energy, kinetic energy, and power. When a force acts upon an object to cause a displacement of the object, it is said that work was done upon the object.
