Chapter 15 Energy Flashcards
energy
the ability to do work
kinetic energy
energy of motion
potential energy
energy stored up
gravitational potential energy
an objects weight & position
elastic potential energy
stored up energy of objects that are stretched or compressed
mechanical energy
motion & position of objects
thermal energy
kinetic & potential energy of microscopic particles in an object
chemical energy
potential energy stored in chemical bonds
electrical energy
energy associated w electrical charges
electromagnetic energy
energy that travels in waves
nuclear energy
energy stored in the nucleus of an atom
energy conservation/law of conservation
energy can’t be created or destroyed it can only be transformed
energy transformation/conversion
occurs between different types of energy
solar energy
energy from the sun
geothermal energy
thermal energy beneath the earth’s surface
nonrenewable resource
recourses that are limited (ex. oil, natural gas, coal, uranium)
renewable resource
resources that can be replaced in a short amount of time (ex. solar, geothermal, hydroelectric)
what’s kinetic energy’s equation
1/2(mass)(speed)^2
what’s potential energy’s equation
(mass)(gravity sometimes?)(height)
what’s mechanical energy’s equation
potential+kinetic
