Forms of Energy I
The sun is these two types of energy
Chemical and Thermal Energy
Light and Heat also accepted as answers
When you stretch a rubber band, you give the rubber band
What is the equation for Potential Energy?
GPE= mass x gravity x height
OR
GPE = Weight x Height
This form of power comes from turbines spinning around and converting each spin into electrical energy
Wind Power
Describe the point in a Roller Coaster where a rider reaches maximum Potential Energy.
The top of the tallest hill of the rollercoaster
Wind Turbines use this kind of energy
Kinetic energy
The Energy of Motion is called
Kinetic Energy
The equation for kinetic energy is...
KE= mass x velocity^2 / 2
This form of power requires the use of photovoltaic (PV) cells by scientists, convert light into electricity
Solar Power
Identify the point in a Roller Coaster ride where the rider has zero potential energy
At the bottom of the lowest hill
A Battery stores this form of energy
Chemical
A bouncing ball is an example of this kind of energy
Elastic Potential Energy
The equation for total mechanical energy...
TME = KE + PE (+ and any other Energy)
This power uses water to make energy
Hydropower
Why can the second hill in a Roller Coaster not be as tall as the first hill?
Energy is lost as the car travels. Due to frictional losses, and so the maximum hill the cars can climb gets smaller and smaller. Putting a bigger hill later on will only make the roller coaster cars roll back down the way it came.
Electromagnetic
When a child swinging on a swing reaches the top of the arc, she has reached her maximum (form of energy)
Potential Energy
Complete the sentence:
Energy cannot be created or ______________.
Destroyed
This is energy that is collected from renewable resources
Renewable energy
Roller Coasters use these five forms of energy
Potential, Kinetic, Sound, Thermal, and Mechanical Energy
A Drum has this kind of energy
Sonic or Sound Energy
A rollercoaster racing down a hill is experiencing these two forms of energy...
Kinetic and Thermal Energy
Energy comes in many forms and can be _____________________ from one object to another as heat, light, or motion, to name a few
transferred
This form of power comes from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma
What happens when a Roller Coaster is breaking? Kinetic energy is transferred into these two forms of energy...
Thermal and Sound Energy
The brakes make sounds and the tracks heat up
