LAPTOP COMPUTER A Picture of an object on a computer is _____ an ICON
REMOTE CONTROL DEVICE b The Gray Cube is a _____
REMOTE CONTROL DEVICE b The Gray Cube is a. b The Gray Cube is a MOTOR. b The motor uses what type of energy to move? ELECTRICITY
ASSEMBLE REMOTE CONTROL CAR b Mount Motor b Gears
REMOTE CONTROL DEVICE b The Yellow BRICK is an RCX Brick which contains a computer. b The Brick uses what type of energy to run? ELECTRICITY b The RCX Bricks will control the Car when we are done. we are done.
ASSEMBLE REMOTE CONTROL CAR b Mount Motor b Gears b Mount RCX Brick b Test Car with Program #1
RECAP b WORK = Force x Distance b ENERGY is the ability to do work b Energy can be potential or kinetic b The Brick will release the same energy every time doing the same work every timedoing the same work every time b Will the car always go the same distance?
Experiment b Begin with a question. b Will the car travel farther on the track or on the carpet surface?
