What is potential energy?
Stored Energy
100
What is kinetic energy?
energy in motion
100
What is thermal energy?
heat is thermal energy it can be transferred from one place by one place to another
100
What does EPE stand for?
Elastic Potential Energy
200
What is an example of Potential Energy?
Roller Coaster sitting on top of a hill
200
What is an example of kinetic energy?
a car rolling down a hill
200
What is the difference between potential and kinetic?
Potential energy is energy waiting to go into motion. Kinetic energy is energy in motion.
200
Name the two sources of Thermal Energy that we have discussed this unit.
Friction & air resistance.
200
When is EPE equal to zero?
When there is no stretch applied.
300
What happens to the GPE when the height is reduced by one half?
The GPE will also be reduced by one half.
300
What happens to the kinetic energy when two objects collide?
kinetic energy transferred from object to object
300
Which law of physics (and the universe!) states that energy cannot be created or destroyed?
law of energy of conservation
300
Which car experiences more thermal energy: a square-shaped car or a wedge-shaped car
square car
300
What are the units of k?
N/m
400
When is the max potential energy in a pendulum?
At the highest points of its swing.
400
If mass is doubled, what happens to Kinetic Energy?
Kinetic energy also doubles.
400
What are 2 types of energy have we not focused on during this unit?
Photo, mechanical, chemical, electrical, magnetic, & nuclear.
400
Give an example of where I can find thermal energy in my everyday life.
Walking, driving, sky diving, throwing something through the air, etc. (anywhere where I encounter friction and/or air resistance)
400
How can I calculate the value of k?
Find the slope of a force vs. distance graph.
500
What is how dose a pendulum represent potential energy?
when it goes up it has GPE
500
What is how does a pendulum represent potential to kinetic energy?
Because when it is at its highest point then it is potential energy and when it rolls down to its lowest point it is kinetic energy.
500
Name all of the types of energy that are utilized when turning on a flashlight.
Chemical --> electrical --> heat & light
500
Give an example of where I can find thermal energy on a car.
Brakes & tires with ground
