Gravitational Potential Energy Flashcards
What is gravitational potential energy?
Gravitational potential energy is the energy an object possesses due to its position in a gravitational field.
What is the formula for calculating gravitational potential energy?
The formula is GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
True or False: Gravitational potential energy depends on the mass of the object.
True
If the height of an object is doubled, what happens to its gravitational potential energy?
It also doubles.
What does the ‘g’ in the GPE formula represent?
The ‘g’ represents the acceleration due to gravity, approximately 9.81 m/s² on Earth.
Fill in the blank: The gravitational potential energy of an object at ground level is _____.
zero
Multiple Choice: Which of the following factors does NOT affect gravitational potential energy? A) Mass B) Height C) Color
C) Color
What happens to gravitational potential energy when an object falls?
It decreases as the object loses height.
True or False: Gravitational potential energy can be converted into kinetic energy.
True
If an object weighs 10 kg and is raised to a height of 5 m, what is its gravitational potential energy? (Use g = 9.81 m/s²)
The GPE is 490.5 Joules.
What unit is gravitational potential energy measured in?
Joules (J)
How does gravitational potential energy change when an object is lifted higher?
It increases.
Multiple Choice: Which object has the greatest gravitational potential energy? A) 5 kg at 2 m B) 10 kg at 1 m C) 2 kg at 10 m
C) 2 kg at 10 m
What is the relationship between gravitational potential energy and height?
Gravitational potential energy is directly proportional to height.
True or False: An increase in mass always results in an increase in gravitational potential energy.
True
Fill in the blank: The gravitational potential energy of an object is highest when it is at the _____ point.
highest
What happens to the gravitational potential energy of an object if it is dropped from a height?
It is converted into kinetic energy as it falls.
If two objects have the same mass but different heights, how do their gravitational potential energies compare?
The object at the greater height has more gravitational potential energy.
What is the significance of gravitational potential energy in understanding energy conservation?
It illustrates how energy can be stored and converted between forms.
