When energy moves from one object to another without changing form, we say it has been transferred
True
False
Select the odd one out
Energy from the sun being stored in a plant
Kicking a football

Watching TV
solar --> electricity --> chemical --> electrical --> heat/light/sound may represent
The Sun’s energy to a Motorola Razr
Energy from coal to a toaster
Tidal energy to a television
The Sun’s energy to a person bouncing a basketball
Which is not a rule of flow diagrams?
The arrow points in the direction of the transformation
The energy input is written at the back of the arrow
The energy output is written at the tip of the arrow
The flow diagram is underlined
The likely flow diagram for someone eating a pizza is
Chemical energy --> Kinetic energy + Sound energy + Heat energy
Chemical energy --> Electrical energy --> Sound energy + Heat energy + Light energy
Chemical energy --> Kinetic energy --> Sound energy + Heat energy
Elastic energy --> Kinetic energy + Sound energy
