Moton Flashcards
Distance
length between two points. Unit is metres (m).
Speed
Distance travelled divided by time taken (m/s).
Time
How long it takes to do something (s).
Distance-time graph
Graph drawn using time on x axis and distance on y axis. The slope gives the speed.
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
Particles that have lost or gained electrons.
Conductors
A substance that allows energy, such as heat or electricity, to pass through it easily.
Insulators
A substance that does not allow energy, such as heat or electricity, to pass through it easily.
Negative
Electrons have a negative charge. If an object gains electrons, it becomes negatively charged.
Positive
An object that has lost electrons takes on a positive charge.
Components
Objects in an electric circuit. The conversion of electrical energy into other forms takes place when that energy passes through these objects.
