Physics Motion Flashcards
Distance
Length between two points (m)
Speed
Distance traveled divided by time taken (m/s)
Time
How long it takes to do something (s)
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
Conductor
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
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
Component
Objects in an electric circuit. The conversion of electrical energy into other forms takes place when that energy passes through these objects
Circuit diagram
An electronic circuit drawn using symbols
Ammeter
Measures the current flowing through a wire. Ammeters are connected in series
Potential difference
When there is a point of high electrical energy and a point of low electrical energy in a complete circuit, we say that there is a difference in electrical potential energy between those points. Provides the energy that pushes electrons around a circuit. It is needed to make a current flow
Voltage
Potential difference in a circuit is also called voltage
