Understanding
potential energy through the animated examples of
gravitational force and elasticity.
|
|
|
|
At atomic
level, the potential energy plays a significant part
in the formation of molecules
|
|
|
|
| All energies are derived from potential
and kinetic energies. |
|
|
|
We come across
energies in many formats - like thermal, light, chemical
in our day-to-day life.

This science animation follows
a macro to micro path by probing deeper into various energies
to unravel their common base - Potential and kinetic energy.
- Introduction to energy and it's types: animation shows
energy is everywhere around us in various forms.
- Elastic, chemical, gravitational, mechanical are all
forms of potential and kinetic energy
- Establishes relationship between potential and kinetic
energy through crane example
- What is potential energy? Explained on basis of work
- Examples of potential energy: F = -du/dx or force field
always tries to lower PE.
- Case 1: Gravitational force - relationship between
PE and position shown by ball and earth's surface
example
- Case 2: Elastic force - stretching of a spring
- Relationship between force and potential energy
- Potential energy at atomic level
- Case 1 - Opposite charges
- Case 2 - Similar charges
- Formation of hydrogen molecule - electron cloud - direction
of rotation of electron.
- Variation of potential energy with inter nuclear distance
- bond formation - Potential well
- How to calculate potential energy?
- What is kinetic energy?
- How to calculate kinetic energy?
- Various forms of energy
- Inter-conversion of energies: Explained in detail by
taking each position of pendulum separately and analysing
the forces acting on it at that position.
- Application of conversion of energy: Hydroelectric Power
Plant from potential-kinetic-mechanical-electric-sound
or light or mechanical energy.
- Explanatory notes Section :
- Potential energy function or how to calculate PE
if force is known?
- Why Negative sign is there in formula of PE ?
