1-8 Energy:Basic Principles

Question 1

Kinetic Energy

Answer 1

is energy associated with motion
such as:
* The motion at the particulate level (thermal
energy).
* The motion of macroscopic objects such as a
thrown baseball and falling water.
 The movement of electrons in a conductor (electrical
energy).
 Wave motion, transverse (water) and compression
(acoustic).
Matter consists of atoms and molecules in motion.

Question 2

Potential Energy

Answer 2

results from an object’s
position:
 Gravitational: An object held at a height,
waterfalls, etc.
 Energy stored in an extended spring.
 Energy stored in molecules (chemical energy,
food)
 The energy associated with charged or partially
charged particles (electrostatic energy)
 Nuclear energy (fission, fusion).
