What is Gravitational Energy?
Energy stored in an objects height above the earth's surface
Energy stored in the movement of an object
Energy stored in thermal energy, light energy, or sound energy
Energy stored in the stretching or compression of something springy
Energy stored in the chemical reactions occurring (specifically in batteries and in the body)
The higher above the ground I get, the ...
More gravitational energy
less gravitational energy
gravitational energy has nothing to do with height
The slower I get, the....
More kinetic energy I have
The less kinetic energy I have
Kinetic energy has nothing to do with speed
What happens to the chemical energy of a battery as it is used?
The chemical energy increases because the more they are used, the more chemical reactions are occuring
The chemical energy decreases because the more they are used, the less chemicals remain in the battery
The chemical energy stays the same because the same number of batteries are being used
Chemical energy has nothing to do with batteries
What does the fact that the pie charts stay the same size mean?
It means that the types of energy always stay the same
It means that the total amount of energy can change, but we are only looking at a certain amount
It means that the total amount of energy stays the same
It doesn't mean anything, that is just how we draw it
a skeleton is walking down the street trick or treating. When he sees his favorite candy, he starts jumping up and down. What types of energy are present?
Kinetic
Gravitational
Kinetic and Gravitational
Kinetic, Gravitational and Elastic
What could this series of pie charts represent?
A battery being charged.
A toy car being charged.
A toy car getting faster over time.
A rollercoaster moving to a stop.
What might this series of pie charts represent?
An elephant jumping.
A rock on a spring that is launched into the air.
A rock is dropped from the air and falls onto a spring.
A remote controlled toy helicopter flying up then down.
In third position (the end), a pie chart for this system would show what types of energy?
Kinetic and heat
Heat
Gravitational
Gravitational and kinetic
You eat a pizza. If you were drawing the energy pie charts for this scenario, how would they change from beginning to end?
All chemical energy --> All gravitational energy
All chemical energy --> chemical, heat, and kinetic energy
All heat energy --> chemical, heat, and kinetic energy
Chemical and gravitational energy --> heat and chemical energy
Why does the initial energy not equal the final energy?
2 units of energy are lost by the system.
2 units of energy are destroyed.
This is impossible and violates the law of conservation of energy.
2 units of energy are gained by the system.
Which description best matches this LOL chart?
(Note Ug = gravitational and Us = elastic energy)
A cart on a spring is launched up into the air.
A cart falls down and eventually lands o a spring.
A car goes up a ramp, eventually hitting a spring.
A cart is thrown up into the air.
In an LOL chart, what goes in the circle?
the types of energy
the objects in system
the objects NOT included
the amount of energy initially
In an LOL chart, you start with 5 units of energy. 4 additional units of heat energy are put into the system from a nearby fire. How much energy is in the system at the end?
