ENERGY TRANSFORMATIONAdam S. Jess S. Caitlin R.

Kinetic Energy

RECTALINEAR: (x,y,z) movement

VIBRATIONAL: back and forth

ROTATIONAL: spinning (no velocity)

ELECTRICAL: electric 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
