Types of Energy
What is the Definition of Kinetic Energy
Energy stored in the movement of an object
How do i represent my object of interest in a state diagram?
A dot
What is an energy pie chart?
A chart that shows the percentages or amounts of different types of energy at certain points in time.
What are the 3 steps to making a system schema
1) write down all of the objects
2) draw the interaction arrows
3) draw your dotted line to show anything inside or outside of the system.
What is a closed system?
A system where every object is inside of the system
What is the definition of chemical energy
Energy stored in chemicals or chemical bonds
If I draw an arrow in my state diagram, what does that mean?
it means your object of interest is moving
If air impacts the object's motion, what kind of energy is in my pie chart from the air resistance
Dissipated Energy
What is one object that we know interacts with everything in the system?
Earth's Field
What is an open system?
A system where not everything is inside of the system. There are surroundings.
What is the definition of elastic energy
Energy stored in the stretching or compression of something springy
How do I show that something is moving at the same speed in multiple state diagrams?
You put two tick marks on the arrows
What is our #1 rule about objects in the system and energies we can use in our energy pie chart
You can only use an energy in an energy pie chart if the object that is related to that energy is inside of my system.
What do the arrows in system schema represent? Double sided? Single sided?
The arrows show that objects are interacting. A double sided arrow means that both objects interact with each other. A single sided arrow means only one object interacts.
What is the definition of gravitational energy
Energy stored in the change in height above a starting point
What do I do with my arrows if the speed of the object is changing?
You change the length of the arrow. Shorter arrows mean slower and longer arrows mean faster
Based on these pie charts, explain to me what is happening
A ball is held in the air, and then is dropped, and hits the ground.
What is a significant interaction?
If an interaction is significant, that means that it really affects the movement of the other object
What are the three types of energies that fall under our Dissipated Energy category and describe all of them.
Light energy- if something produces light
Sound energy- if something makes a noise
Thermal energy- if heat is created (example: friction)
Based on this state diagram, explain to me what is happening in this scenario.
Santa is walking up a hill at a constant speed
Explain why a pie chart would get smaller or why a pie chart would get larger
A pie chart would get smaller if something inside of the system gave energy to something outside of the system.
A pie chart would get bigger if something outside of the system gives energy to something inside of the system.
