Motion
The action of moving to one place to another
Motion
If the circuit has any gaps, or breaks, it is called an incomplete or
open circuit
The flow of electrons (-) from one side to other.
Electricity
When a change makes a new substance
chemical change
Heating water and make it become steam
Evaporation
act on a object and make it move or change its motion
forces
the electrical current flows to the different components through a single path
series circuit
A material that allows electricity to flow easily
conductor
The substance or material can't be returned to its original form
Irreversible change
separating two or more solid components of different sizes by passing them through a sieve
sieving
Involves a round object turning over and over along a surface
rolling friction
the electrical current fl ows to the different components through different paths
parallel circuit
When a material does not conduct electricity easily
insulator
Needs heat, oxygen and fuel to happen
combustion
When you can see the components of a mixture
heterogeneous
Force = mass x acceleration means
the more mass, the more force to move
the less mass, the less force to move
two or more wires that shouldn’t be in contact with each other connect or touch. This high voltage makes the wires heat up.
Short circuit
the buildup of electrical charge on the surface of an object when two objects come in contact
Static electricity
Fireworks is an example for
explosive combustion
It refers to the kineticenergy (motion) of atoms in the substance.
Temperature
Calculated as distance/time
speed
laptops and smartphones are very powerful electronic devices that have lots of components are examples of
complex circuits
the fl ow of electrical charge through a conductor, such as wires, from one place to another within certain time.
Current electricity
Expansion
refers to how much matter an object has in relation to its volume.
Density
