5) … a form of potential energy related to the breaking and forming of
chemical bonds. It is stored in food, fuels and batteries, and is
released as other forms of energy during chemical reactions.
6) … a form of energy that is transferred by a difference in temperature.
7) … energy of the moving parts of a machine. Also refers to
movements in humans.
8) …is when two nuclei are joined together under
millions of degrees of
heat.
III. Are these sentences true or false?
1) The force is equal to the weight of the object.
2) Energy (E) can’t be defined as the capacity for doing work.
3) The simplest case of mechanical work is when an object is standing
still and we force it to move.
4) The energy of a moving object isn’t called kinetic energy.
5) There are four types of energy.
6) The first is Kinetic Energy or Energy of Motion, the second is
Potential Energy or Stored Energy.
7)
To calculate Work, we can’t use the equation W=Fd, where F - force,
d - distance.
