Energy
the capacity to do work
Work
the action of a force through a distance
Total energy
sum of an object’s kinetic energy and potential energy
kinetic energy
the energy associated with an object’s motion
potential energy
the energy associated with an object’s position or composition
thermal energy
type of kinetic energy associated with the temperature of an object
the law of conservation of energy
energy is neither created nor destroyed
systems with high potential energy…
tend to change in ways that lower their potential energy, transferring energy to the surroundings.
objects or systems with high potential energy tend to be…
unstable
Chemical potential energy
arises primarily from electrostatic forces between the electrically charged particles that compose atoms and molecules (protons and electrons)
