Physics Flashcards
Distance
Length between two points
Speed
Distance traveled divided by time taken
Time
How long it takes to do something
Magnet
Pieces of metal that attract other substances.
Magnetic material
Materials magnets attract. For example, iron, steel, cobalt and nickel, as well as other magnets.
Poles
Two opposite ends of a magnet at which the magnetic field is at its strongest.
Magnetic field
The space around a magnet that exerts a force on magnets and magnetic materials.
Magnetic field lines
The directions of forces in a magnetic field are represented by magnetic field lines.
Compass
A small magnet allowed to move freely on a pivot. The direction the compass needle points is the direction of the magnetic field lines.
Alloy
A mixture of two metals. Steel contains iron and cobalt
Current electricity
The steady flow of charge though wires and circuits.
Static electricity
When two objects come into contact, electrons can transfer between them. When this happens, both objects become charged with static electricity.
Charged particles
When two objects come into contact, electrons can transfer between them. When this happens, both objects become charged with static electricity.
Conductors
A substance that allows energy, such as heat or electricity, to pass through it easily.
Insulator
A substance that does not allow energy, such as heat or electricity, to pass through it easily.
