SIS skills
Aim: The purpose, starts with "to investigate"' or "to determine"
Independent variable (IV): variable we can change
Dependent variable (DV): what we measure
Controlled variable (CV): variable we keep the same
Graphing (PLUST): IV go on the x - axis and DV go on the y -
PRACTICE QUESTION:
Aim: To determine how the colour of a car effects how fast it can travel
IV:
The colour of the car
The brand of the car
How big the car is
How many passengers in each car
DV:
How fast the car drives
CV:
Number of wheels
Weather (not do one rainy and one sunny)
Type of surface
⚡Energy

Definition✅
Energy: The ability to do work or cause change.
Energy is measured in joules (j)
There are 2 categories
Kinetic energy: The energy an object has because its moving
Potential energy: stored energy
They both have lots of different types of energy

Types of kinetic energy pt 2🏃➡
Type of energy | definition | Two facts | Three examples |
Kinetic energy
🏃➡ | It is the energy an object possesses due to its motion | Formular = KE= (1/2) mv2 The faster or heavier an object is the more kinetic energy it has. It can be transformed into heat and sound energy.
| A rolling ball A moving car A flying bird
|
Light (radiant) energy 💡 | Light energy is a type of kinetic energy from electromagnetic radiation It is visible to the human eye | It travels in waves and doesn't require a medium Produced by exited atoms, light can be absorbed | Sunlight Lasers Electric bulbs |
Heat (thermal) energy 🔥 | Thermal energy or heat energy, is kinetic energy off vibrating atoms and molecules | As temp increases, particle motion speeds up, raising thermal energy Heat moves naturally from warm to cool | Boiling water Sunlight warming the ground Burning fire
|
Sound energy 🔊 | Sound energy is the kinetic energy produced by vibrating objects that create pressure waves in a medium | It travels through air, water and solids. The sound intensity depends on the vibrations strengths | Music Thunder Engine noise |
Mechanical energy ⚙ | Mechanical energy is the sum of an objects kinetic and potential energy due to its motion and potential. | It's the energy associated with physical systems that more or have the potential to move | A spinning turbine Rolling wheel
|
Electrical energy
⚡ | Electrical energy is kinetic energy from moving electrical charges | It results from the flow if charges through the conductors The faster electrons move more the energy is carried | Lightning Electrical currents Batteries
|
Types of potential energy pt.2 🫙
Types of energy | definition | Two facts | Three examples |
Potential energy 🫙 | Potential energy I stored energy an object has because of it position, shape or structure | Potential energy can transform into kinetic energy Includes gravitational energy
| A raised rock A compressing spring Fuel in a tank |
Gravitational potential energy 🌏 | Gravitational potential energy is the energy stored in an object due to its height and mass. | Depends on how high the object is above the ground and the strength of gravity It turns into kinetic energy | A tree branch A rock on a cliff Water behind a dam |
Elastic potential energy 🏹 | Elastic potential energy is stored energy in objects that can stretch or compress | When rubber or metal is deformed energy is stored due to its ability for return to its original shape. | A stretched rubber band A compressed spring A string on a bow |
Chemical potential energy 🧪 | Chemical potential energy is energy stored in the bonds between atoms and molecules | During chemical reactions these bonds are broken Or re arrange releasing or absorbing energy. This powers living organisms | Food batteries Explosives. |
