Speed vs. Kinetic Energy
When speed triples, kinetic energy increases by this factor.
What is 9 times?
This type of potential energy increases as you lift an object higher.
What is gravitational potential energy?
At the top of a roller coaster hill, this type of energy is at its maximum.
What is potential energy?
A car traveling 60 mph has this much more kinetic energy than the same car at 30 mph.
What is 4 times more?
When you stretch a rubber band, you store this type of potential energy.
What is elastic potential energy?
At the bottom of a roller coaster hill, this type of energy is at its maximum.
What is kinetic energy?
In the kinetic energy formula KE = ½mv², speed is raised to this power.
What is the second power (or squared)?
Moving two magnets with the same poles closer together does this to potential energy.
What is increases potential energy?
When a pendulum swings, energy constantly changes between these two types.
What are kinetic and potential energy?
If you want to reduce kinetic energy by half, you must reduce speed by this factor.
What is √2 (square root of 2) or about 0.7?
A model showing gravitational potential energy would include these three main factors.
What are mass, height, and gravity?
A compressed spring in a toy car stores this type of energy that converts to kinetic energy when released.
What is elastic potential energy?
The steepness of a kinetic energy vs. speed curve increases in this manner as speed increases.
What is exponentially (or gets steeper and steeper)?
When objects interacting at a distance change arrangement, the potential energy change depends on these two factors.
What are the distance between objects and the strength of the interaction?
In a system where a ball rolls up a ramp, the total of kinetic plus potential energy follows this principle.
What is conservation of energy (or stays constant)?
