ENERGY TRANSFORMATION
Kinetic Energy
 RECTALINEAR: (x,y,z)
 ELECTRICAL: electric
movement
 VIBRATIONAL: back
and forth
 ROTATIONAL:
spinning (no velocity)
current
 EM RADIATION:
visible/invisible waves
(light, micro, gamma,
ect.)
 HEAT: any particle
movement (no energy
can be used without
some turning to heat)
How Boat Engine Works
 Pull start cord
 Air + fuel injected into piston




chamber
Piston compresses gas/air
mixture
Battery send energy to spark
plug
Spark plug ignites gas/air
Moves piston down which turns
shaft and moves next piston up
compressing next gas/air

Happens over and over again
 Shaft turns which turns propeller
Rectilinear
 Pull start cord
 Boat moves
Electrical
 Battery sends
electricity to spark plug
ignites fuel
EM Radiation
 Electric current creates
electromagnetic field
 Form of EM Radiation
Vibration
 Piston moves up and
down
 Hole motor vibrates
Rotational
 When pistons travel
up/down turns crank
shaft which turns drive
shaft which turns
propeller
 Another shaft turns
alternator which
charges battery
Heat
 All these energy
transformations create
heat
 Explosion
 friction
 Particle movement
