Energy is Everywhere
The Law of Conservation of Energy states that energy cannot be ______ or ________.
Created or Destroyed
a battery that is not being used has _________ energy
Chemical
What type of energy transformation is this:
standing still ---> walking
potential ---> kinetic
A person running down a hill is an example of _______ energy.
kinetic
What type of energy does a plant need in order to grow?
Light Energy
Rubbing your hands together produces this type of energy
Thermal
What type of energy transformation is this:
battery --->remote to turn the tv on
chemical --> electrical
A person sitting in a chair has mostly _________ energy.
Potential
True or False: An object can be 100% of two different types of energy at the same time.
False
An apple hanging from a tree has this type of energy
Gravitational
What type of energy transformation is this:
gasoline ---> moving car
chemical ---> mechanical
Kinetic energy is energy that is _______ and gains _______.
moving and gains speed
This type of energy allows us to see things that we CANNOT normally see with our eyes. (visible and non-visible waves)
Electromagnetic energy
Food and batteries are examples of chemical potential energy because why?
They both have stored chemical energy that can be used to give something else energy for a short amount of time.
What TWO types of energy transformation is this:
outlet ---> lightbulb in a lamp
electrical --> light --> thermal
electrical --> thermal --> light
electrical --> light
light --> thermal
Where on a rollercoaster is there 100% potential energy, 100% kinetic energy, and 50% potential and kinetic energy?
100% potential at the top of the biggest hill
100% kinetic at the bottom of the hill
50% potential and kinetic in the middle of going down the hill
Which thing has more energy: an elephant or a human
Why?
An elephant because it has more mass (is bigger) and objects with more mass have more total energy
Provide an example of mechanical energy and explain why it has mechanical energy
*Explanation must have to do with the continuous motion for the object to move
Why is energy transferred?
What are the two MAIN types of energy?
Categorize these types of energy under the two main types: Thermal, Mechanical, Electrical, Chemical, and Gravitational
Kinetic: Thermal, Electrical, Mechanical
Potential: Chemical and Gravitational
