End of Years

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune My Very Educated Mother Just Served Up Noodles

Planets orbit stars while moons orbit planets

The Earth sits on an axis, which means that at any given point in the year, one hemisphere will be tilted towards the sun and one will be tilted away from the sun. The hemisphere tilted towards the sun will receive more intense sunlight and so will experience higher temperatures I.e. Summer. Over the course of the year, the Earth orbits the sun and the hemisphere tilting towards it will swap.

Seasons are different because for part of the year, the northern hemisphere will be tilting towards the sun resulting in a higher temperature while for the other part of the year the southern hemisphere will be tilting towards the sun resulting in a higher temperature. At this time, the northern hemisphere will be tilting away from the sun so will not be exposed to as much sun which means that it will have a lower temperature.

Make a stationary object remain stationary or make a moving object continue.moving at a steady speed ina straight line

It can make a stationary object start moving/accelerate It can make a moving object Accelerates in the direction of the resultant force

Newtons (N) using a newton meter

• Kinetic - Energy in movement (speed) • Gravitational - Energy stored by placing something high up (where it can fall) • Elastic - Energy stored in springs, etc. • Thermal - Energy stored as heat • Chemical - Stored in chemicals (food, petrol, etc.) • Nuclear - Stored in atomic nuclei (nuclear power) • Electrostatic - Stored as electric charge build up • Magnetic - Stored by separating magnets

An energy transfer is when you convert one type of energy to another 1.By Heating 2. By Radiation - By either light or sound 3. Electrically 4. Mechanically - by physically pushing or pulling, applying a force.

Advantages are it is most abundant renewable energy source and will never run out Disadvantages are it isn’t very efficient and their are intermittency issues based on locatopn

It has low operating costs and accounts for 11% of global electricity genration Many nuclear accidents occur and and nuclear waste is very dangerous

Consistent power generation and is very reliable Accidental release of of CO2 and hydrogen sulfite emmisions

It has no direct co2 emissions and makes use of otherwise you useful products and won’t turn out It relies on unreliable product and is an eye sore

Weight changes and mass does not Weight is the force from gravity and is measure in Newtons Mass is the amount of matter in an object and is measure in g or kg

Weight = mass x g (10N/kg)

1N

0.1kg =1N

Force = pressure x area

Heat/ thermal energy waves

Absorber will get the hottest Reflector will be the coldest

Average speed=distance/time

Newtons (N)

Weight – the Force due to Gravity • Friction • Drag – Air resistance or water resistance •Upthrust – Floating force • Tension – in rope • Elastic Force – in a spring • Contact Force – from a surface •Magnetic Force
