Energy Transformations
Using a battery
chemical energy ----> electrical energy
What is the general definition of energy conservation
energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside.
Energy that has the ability to fall; this type of energy increases the higher up you go.
Gravitational potential energy.
A plant going through photosynthesis has an energy transformation, what types of energy do we observe to be transformed
light energy -> chemical energy
How will you increase the kinetic energy of a ball with the mass of 5 kg
increase the speed
Define Potential Energy
Energy can only be
Transferred
An object is pulled all the back and ready to be released increases
Elastic Potential Energy
Using the sun to grow food
Light energy ------> chemical energy
Name one way you can increase potential energy
Increase height or increase mass
A person running down the sidewalk has this type of energy.
(Mechanical) kinetic energy.
What is the only visible form of energy?
light energy
Define gravity.
The force of attraction between all objects in the universe. The earth pulling objects downward
Energy can be transferred as (list 4 possible answers)
Light, heat (thermal) , motion (kinetic), sound
With a roller coaster where is the greatest potential energy
when the car is raised at the highest
A person that has just jumped from an airplane has this type of energy.
(Gravitational) potential and kinetic energy.
The sun is an example of this type of energy.
Heat, (Thermal) or Gravitational
List the Law of Conservation of Energy.
Energy can be not be created or destroyed.
