Energy - Source of energy and Measures

The study of energy begins with the source of energy. Energy is the product of movement and law. Nothing exists without it. It can not be found "below", in the simplest forms of life, or far away on distant planets or stars. It can not be found. It finds you because it created you. It's source is the Triune GOD. Energy comes from above and outside of time. God moved. The glory of God is light. His light is a creative law order. He moved, His light came and that is the source of all energy!

God's energy, glory and law order produced heaven and earth. Matter and measures were created. Matter has different "measures". But always remember that God is the "Source" and the "heavy weight". He is the energy that created and defined the "measure" of matter and everything else.

With that said let's start today's lessons found at BBC Schools:

1. Measuring length

• Length is a measure of how long or wide something is.
  Rulers and tape measures can be used to measure length.
• Length is measured in millimetres (mm), centimetres (cm),
  metres (m) or kilometres (km). These are known as
  metric units of length.
  1 cm = 10 mm
  1 m = 100 cm
  1 km = 1000 m
• Estimating length
  1 cm is about the width of a staple
  1 m is about the width of a single bed
• Miles, feet and inches are old units of length. These are
  known as imperial units of length but are not now
  commonly used in maths.
  There are 12 inches in a foot.
  An inch is roughly equal to 2.5 centimetres.
  A foot is roughly equal to 30 centimetres.
  A mile is roughly equal to 1.5 kilometres.

2. Measuring mass

• Mass is a measure of how heavy something is. Scales can
  be used to measure mass.
• Mass is measured in grams (g), kilograms (kg)
  and tonnes. These are known as metric units of mass.
  1 kg = 1000 g
  1 tonne = 1000 kg
• Estimating mass
  100g is about the mass of a small apple.
  1 kg is the mass of a bag of sugar or a litre of water.
• Ounces and pounds are old units of mass. These are
  known as imperial units but are not now commonly used in maths.
  There are 16 ounces in a pound.
  An ounce is roughly equal to 25 grams.
  A pound (454g) is equal to just under half a kilogram (500 g).s

3. Measuring capacity

• Capacity or volume is a measure of how much space
  something takes up. Measuring spoons or measuring
  jugs can be used to measure capacity.
• Capacity is measured in millilitres (ml) and litres (l).
  1 l = 1000 ml
• Estimating capacity
  5 ml is about the capacity of a teaspoon.
  1 l is about the capacity of a large carton of fruit juice.
• Pints and gallons are old units of capacity (imperial units).
  There are 8 pints in a gallon.
  A pint is equal to just over half a litre.
  A gallon is roughly equal to 4.5 litres.

4. Reading scales

To read a scale, first work out how much each mark or division
on the scale represents.

5. 12-hour and 24-hour time

• am is morning time (all times between 12 midnight and
  12 midday).
• pm is afternoon and evening time (all times between 12
  midday and 12 midnight).
• This is an analogue or a 12-hour clock. An analogue clock
  is one with a face and hands. It is showing the time
  twenty past five.
  
  If it were twenty past five in the morning, it would
  be written as 5:20 am.
  If it were twenty past five in the afternoon, it would
  be written as 5:20 pm.
• These are digital or 24-hour clocks. They are also
  showing the times twenty past five.
  
• The 24-hour time is the same as the analogue time in the
  morning (except for the 0 at the beginning for numbers
  under 10). So 8:45 am becomes 08:45.
• But in the afternoon, you need to add 12 to convert an
  analogue time to a 24-hour time. So 8.45 pm
  becomes 20.45.
• Midday on a 24-hour clock is shown as 12:00.
• Midnight on a 24-hour clock is shown as 00:00.

6. Units of time

• 1 minute = 60 seconds
• 1 hour = 60 minutes
• 1 day = 24 hours
• 1 week = 7 days
• 1 fortnight = 14 days
• 1 year = 12 months = 52 weeks = 365 days
• 1 leap year = 366 days
• Remember "30 days has September, April, June and
  November. All the rest have 31. Except for February
  alone, which has 28 days clear but 29 each leap year."
