  1. SIMPLE MACHINES Wheel and Axle Screw Pulley Wedge Revierw A machine is a device that makes physical tasks easier. Lever Inclined Plane

  2. What is a… Simple Machine Wheel and Axle Screw • Simple machines are machines with few or no moving parts. • There are six simple machines, they are: 1. Lever 2. Inclined Plane 3. Wedge 4. Screw 5. Wheel and Axle 6. Pulley Wedge Pulley Inclined Plane Lever

  3. What is a Lever? • A hammer is a lever that helps do work. • Work is done whenever force makes an object move.

  4. What is a Lever? • A hammer is a lever that helps do work. • Work is done whenever force makes an object move. • Other examples include a seesaw, crowbar, baseball bat and rake

  5. Levers Lever Load Fulcrum

  6. What is an Inclined Plane? • A ramp is an inclined plane. • A ramp helps move objects. • You can use an inclined plane to help move an object to a higher or lower place.

  7. Inclined plane

  8. What is a Screw? • A screw is a simple machine used to hold objects together. • A screw has a thread and is another example of an inclined plane, it is a curved ramp.

  9. Screw A screw is an inclined plane wrapped around a post. It’s a curved ramp.

  10. What is a Wedge? • A doorstop is a wedge. • A wedge is a simple machine used to push objects apart. • An ax is a wedge that splits wood.

  11. Wedge Two inclined planes make a wedge.

  12. Wheel and Axle Wheel Axle

  13. What is a Pulley? • Made of rope and string wound around a reel to change the direction of a force. • You can use a pulley to move a load up, down or sideways.

  14. Pulleys Wheel Rope This box is easier to lift because of the pulley.

  15. What is a…Wheel and Axle? • A wheel that turns on a rod to help move things quickly and easily. • The axle, or rod, turns when you put force on the wheel. • You probably have seen a wheel and axle on scooters, cars,

  16. Wheel and Axle • The screw driver is an example of a wheel and axle, where the screw or bolt is the axle and the handle is the wheel. The tool makes the job easier by changing the amount of the force you exert. Wheel Axle

  17. Compound Machine • Is 2 or more machines working together • Examples include a Bike or a Car

  18. Machines are Important! • Simple and Compound machines are so important because without them we can’t have… • COMPUTERS, TELEVISION, Mobile PHONES, TELEPHONES, and Even FOOD (especially). • Just imagine what life would be like!
