A mind map about gravity, magnetism, sounds, light, and electrostatic. It involves brief introductions to each item.
Big Idea 2
Gravity is a force that affects objects at a distance.(Non-Contact)
It pulls objects down to Earth.
Gravity helps us stand and run.
A force of a magnet is called magnetism
A magnet is natural and permanent and an electrmagnet is man-made and temporary.
Every magnet has two poles, North and South.
Electromagnet uses electricty to create magnetic field.
Opposite poles attract each other.
Same poles repel each other
When two surfaces touch each other electrostatic force generates.
One object has positive charge and other has negative charge.
Imbalance of positive and negative charge create static electricity.
Light is formed by particlescalled phorons.
Light is a source of energy.
Light can be Reflected Refracted or Absorbed.
Air carries sound in the form of wavesand viberations.
Sound trvels faster in solids.
There are 2 types of sounds'Audible and Inaudilble'
