6/2 Title and make a list
• List 3 Criteria for your maglev car
project
– Must float
– Motor must PUSH

– Must house a 1x1x5 inch piece of cargo
– Wires must contact track behind the car
Exploring Technology - Lesson 7
• Energy is the capacity to do work.
–Lifting a weight
–Heating a room or material
–Pushing a vehicle
• Potential energy (stored) is often
converted into Kinetic energy
(motion)
Energy
•
•
Energy can be used to
do work using several
processes.
Energy can be
potential or kinetic
• Power is:
– the rate at which energy is converted from one
form to another,
– transferred from one place to another, or
– the rate at which work is done.
We can walk up the steps or run.
Either way, the same amount of
work is done. Running does it faster
and requires more POWER.
• Much of the energy used in our
environment is not used efficiently.
–Automobile engines < 20% efficient
–Hot water heater
–Electrical power plants
Conservation is the act of making better use of energy
Power Systems
• Automobile
• Airliner
Power Systems
• Locomotive
• Grain Mill
10/20 Add to yesterday’s drill
• Transportation vehicles are made up of subsystems
that must function together for a system to work
effectively.
– Structural
– Propulsion
– Suspension -What holds it up in its environment?
– Guidance - What helps the operator know where to go?
– Control-How does the operator make it stop, go, turn?
– Support

• Identify a change you made to your maglev car
based on testing.
• Describe the result of the change.
– Ex. “We removed and flipped over our front magnets
because the stuck to the track. The car floated well as
a result of the change”
