PS Chapter 4 Flashcards
energy
ability to cause change
kinetic energy
energy in motion
potential energy
energy that is stored
gravitational potential energy
energy that is stored because of an object’s position
elastic potential energy
energy that is stored because of an object’s shape
chemical potential energy
energy that is stored in chemical bonds that can be broken and formed
Joule
unit for energy and work
mechanical energy
combination of kinetic and potential energy
Law of Conservation of Energy
amount of energy in a closed system remains constant; total energy you begin with has to equal amount of energy you end with
work
moving a force through a distance
power
rate at which work is done
Watt
unit for power
unit for power
Watt
rate at which work is done (W/t)
power
moving a force through a distance (Fxd)
work
energy cannot be created or destroyed; it can just transform from one form to another
Law of Conservation of Energy
sum of all of the kinetic and potential energy
mechanical energy
unit for energy and work
Joule
energy stored in chemical bonds that can be broken and formed
chemical potential energy
energy stored because of an objects shape (being stretched out or squished together)
elastic potential energy
energy that is stored because of an object’s position above the ground
gravitational potential energy
energy that is stored
potential energy
energy in motion
kinetic energy
ability to cause change
