Forces and Energy

Forces can affect objects close to it or far away

Gravitational forces affect us at the surface and pull on objects from many miles away

Magnetic forces protect us from particles from the sun

Energy travels in different ways

Sound waves need a medium to travel through

Light doesn't need a medium to travel through

Energy can be passed on

conduction

Radiation

Convection

Energy is never created or destroyed

The sun releases energy and doesn't create it

Energy can be changed
