Help explain that the unit of work and energy is the definition of Joule I still don't understand the online version. Please help me to explain it again The explanation I read on the Internet is: the unit of work and energy is Joule. Joule is equivalent to a Newtonian force (n). The work done by the point of action moving one meter in the direction of the force is 1 joule = 1 N · M

First of all, we need to understand what is energy and what is work. Their units are the same. Energy refers to energy, which is the physical quantity determined by the motion state of an object, that is, its state quantity, such as thermal energy, potential energy and kinetic energy. Work is the physical quantity related to the change process of the motion state of an object. In short, work is the result of the change of the energy and the motion state of an object

How many joules of heat can 100 million degrees centigrade produce
I don't know how many joules are 100 million degrees centigrade

Your concept is wrong. Centigrade is used to measure temperature, not heat
For example, if you boil a glass of water or a pot of water, when they boil, it's 100 degrees Celsius. But the heat absorbed is different
