### DefinitionsK and L

Kinetic Energy
• Moving energy
Kidney
• Filters the blood
• Makes urine (urea, salt, water)
• Renal artery = brings in dirty blood
• Renal vein = clean blood out
Kilowatt Hour
• Unit of electricity from ESB
• One kilowatt used for 1 hour
• Sums
• Change watts to kW (watts ÷1000)
• Change minutes to hours if needed (mins ÷60)
Litmus
• Indicator
• Blue in base
• Red in acid
Luminous
• Gives out light
Lever
• Rigid body free to rotate around fixed point called the fulcrum
Law of Lever
• When a lever is balanced
• Sum of the clockwise moments is equal to
• The sum of the anti-clockwise moments
• Moment = force x distance (perpendicular)
Ligament
• Joins bone to bone

Bone

Bone

LED
• Light Emitting Diode
• Gives out light when current passes through it
• Electricity allowed through one way only
• Must be connected to resistor to protect from too much current
• Minus of LED to minus of battery
Limewater
• Turns milky with carbon dioxide CO2
• Hons (write out equation before next click)
• Ca(OH)2 + CO2  CaCO3 + H2O
LDR
• Light Dependent resistor
• Light lowers down resistance and lets current through
• (more light more current )
• IN LIGHT METERS

Level = latent heat

Latent Heat
• Hidden heat
• Used to change the state
• From solid to liquid or
• Liquid to gas
• Heat goes in but

temp stays the same

Also opposite direction

- cool down not heat up

Law of Lever

• Ligament
• LED
• Limewater
• LDR
• Latent Heat
• Do I know it??
• Kidney
• Kilowatt hour
• Kinetic Energy
• Litmus
• Luminous
• Lever
