3 cards from this section. Quick, good the night before a test.
What does gravitational potential measure?
Think about work in relation to gravitational fields.
Is gravitational potential positive or negative?
Consider the work needed to move away from a mass.
What does gravitational potential always represent?
Think about the direction of work required.
True or False: Equipotential surfaces require work to move along them.
What does 'constant' imply in this context?
A spacecraft is to be launched from the surface of the Earth. Using the concept of gravitational potential, explain how the gravitational potential changes as it rises and how this relates to the work required to escape the Earth’s gravity.
Consider the idea of moving from a potential well.
Calculate the relative work done in moving a mass from a height of 10 meters to a height of 20 meters in a gravitational field with an acceleration of 9.81 m/s^2. Discuss how potential changes.
Use the formula for gravitational potential energy and remember that potential energy relates directly to height.
