The energy stored in a system due to the positions of objects in the system that are interacting at a distance is called this.
What is potential energy?
100
The energy an object has due to its motion is called this.
What is kinetic energy?
100
If a 4 kg object and an 8 kg object move at the same speed, the _____ object has more kinetic energy.
What is the 8 kg object?
100
Kinetic energy _____ as speed increases.
What is increases?

This scientific law states that the total energy of an isolated system always remains the same.
What is the Law of Conservation of Energy?
200
A rock at the top of a hill is an example of this type of energy.
What is potential energy?
200
This is how speed affects kinetic energy.
As speed increases, kinetic energy increases.
200
This happens to the kinetic energy if the mass of an object doubles.
The kinetic energy also doubles.
200
This is the reason that the relationship between kinetic energy and speed is nonlinear.
What is the graph is not a straight line because they do not change at the same rate?
200
This is the reason a system may APPEAR to lose energy.
What is energy may be transferred to another object or into another form.
300
An object has the most potential energy when it is in this position.
What is the highest position?
300
This is how mass relates to kinetic energy.
More mass results in more kinetic energy.
300
If mass increases, kinetic energy increases in a ____ ratio, forming a ___ line on a graph.
What are constant and straight (or proportional)?
300
The picture on the ___ (left or right) could be a graph for kinetic energy and speed.
What is the picture on the right?
300
These are some other forms that energy can transfer into.
What is sound, friction, or heat?
400
These factors affect the amount of potential energy in a system.
What are the height and mass of the object?
400
This is an example of kinetic energy in action.
Answers will vary: A car driving down the road, a rock rolling down a hill, etc.
400
The picture on the _______ (left or right) might be a graph for kinetic energy and mass.
What is the picture on the left?
400
This is how doubling the speed of an object affects its kinetic energy.
What is the kinetic energy increases by a factor of four? (Remember: kinetic energy = speed squared.➡️ 2 squared = 4)
400
This is the process of energy transformation in a roller coaster.
What is potential energy is at its maximum at the highest point of the coaster, which transforms into kinetic energy as it descends.
