My daughter has driven me nuts with this all night, it's homework. I can't complete the list of 20 examples. I'm stoopid
Oh and not that she is but her teacher teaches by rote. The kids don't get to explore or discover. They just get these 'go find me' lists.
In advance of anyone helping thank you
hehe - I was really bad at physics, so don't beat me up if these are wrong.
I seem to remember that brakes convert kinetic energy into heat via friction.
Turbines convert kinetic energy into electrical or mechanical energy.
That is my schoolboy physics exhausted, I am afraid
EDIT: Misha is here! He knows about engineery type things
Drumsticks hitting drums – conversion to sound
Wind turbine – conversion to electricity
Friction / rubbing sticks together – conversion to heat
Ball thrown up in air – conversion to potential energy then back to kinetic energy on the way down
Particle accelerator – conversion to matter
Kinetic energy converts to mechanical energy in a turbine setup.
In a gasoline engine, kinetic energy in the expanding gas fumes converts to the mechanical, linear movement of pistons in the engine that turn the crankshaft.
Potential energy is easier to think of :
Draw your foot back by bending the knee (potential) and kick the student that does not look things up (kinetic). Of course, we don't kick students, do we - not in physics classes...
How about pushing an old push-mower to turn the blades to cut grass - kinetic to mechanical.
Rubbing your wet hands together to evaporate the water into the air - Kinetic coverts into heat.
Did you know that the latest way to dry your hands uses kinetic energy from moving air quickly through a vortex that swirls the air in such a way that it heats up through compressing the air before it comes out to dry your hands instead of using a heating element to geat the air.
