How do you know how energy is carried by matter?

Answer 1

when u find any kind o energy transformation taking place during an event then we can say that the matter involved in the event has carried some matter. For example; we have a two metal balls which collided, which consider to be an event, will have some energy transfer. say, the velocities of balls might differ as some amount of energy has been converted into sound (in air). then you may again get a doubt "what if any event does not take place?" according to mass energy equation [E=m(C*C)] mass and energy are inter-related every energy has mass and and every mass has energy. so every mass has energy. it is hat fact that basing on the frames of reference one may find that there is no energy possessed by a body. for example; lets consider a wooden block on the ground. for a person on the ground ( same level) will feel that the wooden block has no energy but for a person who is 1km deep ( consider that a person has dug 1km deep tunnel which is just beside the wooden block) will feel that the wooden block has potential energy as it is 1km high above him. and to a person on the moon ( say ) will feel that the wooden box has angular kinetic energy ( as the earth rotates). so i conclude saying that all objects ( say any mass) will always posses some energy. the forms vary in accordance with the frames of references. **** please don't mind for the punctuations( upper and lower case letters as it was not auto-edited)**************
