the energy an object has due to its motion
kinetic energy
stored energy that results from the position or shape of an object
potential energy
kinetic or potential energy associated with the motion or position of an object
mechanical energy
energy sources that are not replaced naturally
nonrenewable energy
produced by nuclear fission reactions
nuclear energy
two things that kinetic energy depends on
speed and mass
living things rely on
chemical potential energy
example of mechanical energy
pogo stick
easily replaced by natural methods
renewable energy
used as a fuel source in atomic power plants
uranium
kinetic energy formula
K.E. = 1/2 m v2
dropping a hammer is an example of
gravitational potential energy
what happens if the rider were to descend
gpe would transform into kinetic energy
formed from the remains of plants and animals that lived in the past
fossil fuels
An example for nuclear energy?
The sun, for instance, is constantly undergoing nuclear fusion as hydrogen atoms fuse to form helium.
when kinetic energy is added to water it
boils
gravitational potential energy (GPE) formula
GPE= mgh
how is work used in the pogo stick example
the stick touches the ground, using kinetic energy and remaining gpe to do work on the gas molecules, converting into elastic potential energy
how are fossil fuels used
used directly; like when heating oil
what is nuclear fission?
nuclear fission is a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy.
When you add kinetic energy to a system an object
the particles start to move faster
chemical energy is stored in
food
the cycle of the pogo stick repeats when
all kinetic energy is converted back to gpe
what are fossil fuels usually transformed into
electrical energy
true or false.Atoms are not tiny particles that make up every object in the universe.
false, because atoms are tiny particles that make up every object in the universe.
