2. What is energy ?
Energy is the capacity of a physical system to perform work. Energy exists in several forms
such as heat kinetic or mechanical energy, light, potential energy, electrical, or other forms.

3. Kinetic energy
energy due to motion example: when we move from place to another

4. Kinetic energy and speed
The faster an object moves the more kinetic energy it has
Example1: when we are setting we have not kinetic energy …but if we moving
so fast we have kinetic energy
Example 2: the tiger moving fast, it has more kinetic energy than
the humans

6. Kinetic energy and mass
If two object move in the same speed the object that has more mass have more
kinetic energy

7. Potential energy
Is stored energy to due to the interaction between objects or praticals
Example: her the boy want to through the arrow it is called potential energy … in the second
part he through the arrow it is called kinetic energy

8. Elastic potential

9. Chemical potential

10. Other forms of energy
Name of the form About this form
Sound energy The energy sound carries on it, the use of
sustained nuclear fission to generate heat and
electricity
Thermal energy The sum of kinetic energy and potential
energy, Thermal energy is a term sometimes used
to refer to the internal energy present in a system in
a state of thermodynamic equilibrium by virtue of its
temperature.
Radiant energy The energy that electromagnetic waves, The
term "radiant energy" is most commonly used
in the fields of radiomatory, solar energy,
heating and lighting.
Nuclear energy Is the that stored and released in the nucleus
of an atom, Nuclear power, or nuclear energy, is
the use of exothermic nuclear processes, to
generate useful heat and electricity.
