place. What can Shondra do to correct her notes?
1. Energy
A Definition - the energy of moving objects
B. Main categories of energy
1. Kinetic - the ability to do work
2 Potential - the energy stored in objects
3. Chemical -- the energy in chemical bonds
C. Forms of energy
1. Gravitational - the energy of a rock on a hill
2 Elastic - the energy in a spring
3. Nuclear - the energy in the nuclei of atoms
4. Electromagnetic wave - the energy from the Sun
5. Electrical - the energy of flowing electrical charges
O Switch "the energy of moving objects" and "the
ability to do work" and place chemical energy under
"Forms of energy."
O Switch "the energy of flowing electrical charges" and
"the energy in a spring" and place kinetic energy
under "Forms of energy."
O Switch "the energy in the nuclei of atoms" and "the
energy stored in objects" and place nuclear energy
under "Main categories of energy."
O Switch "the energy from the Sun" and "the energy of
a rock on a hill" and place electrical energy under
"Main categories of energy."
