What is gravitational potential energy?
The energy an object has due to its position above Earth, energy due to its height
Can energy be transferred? What is an example?
Yes. Answers vary
What is kinetic energy?
Energy of motion
What is potential energy?
Energy stored in an object based on its position.
Does height affect the amount of GPE an object has?
Yes.
What is the difference between potential and kinetic energy?
Kinetic energy is energy of motion and potential energy is associated with the relative position of something.
Does mass effect the KE (Kinetic energy) of an object?
yes
What does "potential" mean?
Having the capacity; develop into something in the future.
What is the formula for calculating GPE?
GPE = mgh (mass in kilograms x gravity x height in meters)
Think of a roller coaster. What types of energy are present in this system?
answers vary- kinetic energy, potential energy, GPE, heat, sound, etc
Does speed effect the KE (Kinetic energy) of an object?
yes
What variable(s) determine the amount of potential energy an object has?
The object's position (height) and its mass.
