Presentation Transcript
kinetic energy
Kinetic Energy
  • Moving energy
kidney
Kidney
  • Filters the blood
  • Makes urine (urea, salt, water)
  • Renal artery = brings in dirty blood
  • Renal vein = clean blood out
kilowatt hour
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
Litmus
  • Indicator
  • Blue in base
  • Red in acid
luminous
Luminous
  • Gives out light
lever
Lever
  • Rigid body free to rotate around fixed point called the fulcrum
law of lever
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
Ligament
  • Joins bone to bone

Bone

Bone

slide10
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
Limewater
  • Turns milky with carbon dioxide CO2
  • Hons (write out equation before next click)
  • Ca(OH)2 + CO2  CaCO3 + H2O
slide12
LDR
  • Light Dependent resistor
  • Light lowers down resistance and lets current through
  • (more light more current )
  • IN LIGHT METERS
l atent heat

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
