1. Energy means the ability to do work
Nothing can stop ENERGY
Energy is done when FORCE moves on an object (work)
Running requires energy
Gravity pulls objects back to Earth (FORCE: Push/pull)
Yo-yo=needs a push or pull to WORK.
You can make different types of energy

2. Different Types of Energy
Light – energy traveling in a straight line
Heat-energy of moving particles
Sound-made through vibrations
Electrical- Charges that flow from one place to the next
Mechanical-kinetic-energy moving
Potential-energy stored

3. Motion and Position
Motion-the movement of an object at any given time.
Position-the location of an object
Gravity- a force that pulls down on an object
Friction- a force that opposes or stops motion

4. Weather is the change in climate caused by wind
Everyday the weather changes
A meteorologist is someone who studies the weather forecast
Tools we use are wind vanes, thermometer, and compass
Heat from the sun powers the water cycle
Evaporation is when water vapor (gas) from the heat of the sun.
Rain, snow, sleet, and hail are forms of precipitation

5. Systems System- All parts that work together to function
Conductors- allow energy to flow through easily. Ex. metals
Insulators- do not allow energy to flow through easily. Ex. Rubber or plastic

6. FLOW OF ENERGY Metal/wire is the conductor Rubber-is the insulator
Battery is the main source of energy

7. Closed circuit-energy flows through easily to work
Open circuit-energy can not be transferred as easily
