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

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

Level = latent heat

• Do I know it??

• Kidney

• Kilowatt hour

• Kinetic Energy

• Litmus

• Luminous

• Lever
