Term
Definition
AMMETER   show
🗑
show The unit for electrical current  
🗑
AMPLITUDE   show
🗑
show The unit for the flow of electricity along a wire. Measured in AMPERES.  
🗑
DAY   show
🗑
DENSITY   show
🗑
show The movement of tiny particles like atoms or molecules that cause them to mix together or move across thin membranes. Diffusion happens because the particles in a substance are constantly moving. Diffusion explains some important processes in biology such as the movement of gas in the alveoli.  
🗑
DIODE   show
🗑
DISPERSION   show
🗑
ECLIPSE of the sun   show
🗑
show A Push or a pull. Measured in NEWTONS (n). It cause an object to SPEED UP, SLOW DOWN OR CHANGE SHAPE.  
🗑
show A force which causes a moving object to slow down.  
🗑
show A short length of wire designed to melt when the current flowing though it gets too high.  
🗑
show One of the three states of matter. (The other two are solids and liquids).  
🗑
show The energy something has caused by it's height  
🗑
GRAVITY   show
🗑
show A material that does not allow electricity or heat to flow through it easily eg wood, glass or plastic to flow through it  
🗑
show The metric unit for energy  
🗑
KILOGRAM   show
🗑
show The energy stored in a moving object  
🗑
LDR   show
🗑
MEASURING CYLINDER   show
🗑
show A natural satellite of the Earth. Orbits the Earth once every 28 days.  
🗑
show The unit for force (and weight)  
🗑
OPAQUE   show
🗑
show A type of circuit where the current divides and follows more than one path.  
🗑
PERMEABLE   show
🗑
PITCH   show
🗑
show An object in orbit around the Sun.  
🗑
show The force on 1 cm² of a surface. Calculated using the formula FORCE ÷ AREA.  
🗑
REED SWITCH   show
🗑
show The word that describes what happens when light bounces off a smooth surface (eg a mirror).  
🗑
REFRACTION   show
🗑
show The property of a conductor that reduces the current flowing through it.  
🗑
show Is the moon a satellite, planet or star?  
🗑
show What is the name given to the rainbow of colours produced by a prism?  
🗑
show Calculated as distance ÷ time  
🗑
show what is being calculated using the formula DISTANCE ÷ TIME  
🗑
STAR   show
🗑
STRAIN ENERGY   show
🗑
show A measure of how hot or cold something is. Measured using a thermometer in degrees Celcius (°C)  
🗑
THERMOMETER   show
🗑
UPTHRUST   show
🗑
show How loud or soft a sound is. Decided by the AMPLITUDE of the sound wave.  
🗑
show Weight is a force on an object caused by gravity. Measured in newtons.  
🗑
YEAR   show
🗑
show Newtons per square centimetre (N/1 cm²)  
🗑
show Grams per cubic centimetre (g/cm³ )
