Simple Machines
Compound Machine
• Made of 2 or more simple machines
• Also known as a complex machine
• Made of 2 or more simple machines
• Also known as a complex machine
Work
Work
• Force is applied over a distance
• Force is a “push” or “pull”
• Use math to calculate• Work =
Force x Distance
Energy
• Ability to do work• Different kinds of
energy
Electricity
Mechanical
Light
Sound
etc.
Computer Workstation
Computer Workstation
• Computer runs the ROBOLAB software
Computer Workstation
• Mouse is used to move the cursor
Computer Workstation
• Mouse is used to move the cursor
Computer Workstation
• Monitor displays icons
• Icons are pictures of an object on the screen
Remote Control Car
• Gray cube is a motor
• Motor uses electrical energy to move
• Gray cube is a motor
• Motor uses electrical energy to move
Remote Control Car
• Yellow BRICK is an RCX Brick
• Contains a computer• Uses electrical energy
to run• Controls the car when
we finish programming it
Assembly of Remote Control Car
Assembly of Remote Control Car
• Gears
Assembly of Remote Control Car
• Gears• Mount Motor
Assembly of Remote Control Car
• Gears• Mount Motor• Mount RCX Brick
• Gears• Mount Motor• Mount RCX Brick
Electricity• Conductor – carries an
electric current
• Insulator – does not carry an electric current
Types of Energy
• Potential – energy of position
• Kinetic – energy of movement
• Potential – energy of position
• Kinetic – energy of movement
Recap
• Work
= Force x Distance
Recap
• Work
= Force x Distance• Energy is capacity to
do work
Recap
• Work
= Force x Distance• Energy is capacity to
do work• RCX Brick will
release the same amount of energy each time
Will the car always go the same distance?
