what are all of the energy stores
thermal, kinetic, gravitational potential, elastic potential, chemical, magnetic, electrostatic and nuclear
1 of 18
what is kinetic energy
it is anything that is moving
2 of 18
what GPE
it happens when you raise an object
3 of 18
conservation of energy=
energy can be stored, transferred between stores, and displaced but it can never be created or destroyed
4 of 18
what are different types of energy transfer
mechanically, electrically, by heating and by radiation
5 of 18
what happens when a bat hits a ball
(bat) kinetic- mechanically- (ball) kinetic
6 of 18
what is the most common way of losing energy in a energy transfer
by heating
7 of 18
what is another principle of energy
energy is only useful when it is transferred from one store to a useful store
8 of 18
total energy input=
useful energy + wasted energy
9 of 18
efficiency=
useful energy transferred by a device/ total energy supplied to a device
10 of 18
what diagram can you use to show efficiency
sankey diagrams
11 of 18
how do you reduce unwanted energy transferred
lubrication (friction)
insulation (heat)
12 of 18
what is a non-renewable energy resource
a resource that will eventually run out
13 of 18
what is a renewable energy resource
a resource that will never run out
14 of 18
what are biofuels made out of
plants and waste
15 of 18
advantages of non-renewable energy resources
reliable and cost effective
16 of 18
disadvantages of non-renewable energy resources
contributes to global warming and sometimes hard to dispose of
17 of 18
what are the current trend in energy resource use
depend on fossil fuels but aim to increase renewable energy resources
