The correct answer is Mass and position.
Potential energy, especially gravitational potential energy, is determined by the mass of the object and its position in a gravitational field (usually related to its height above a reference point).
Which factors determine the potential energy of an object? (1 point)
• Gravity and position
• Mass and position
• Weight and velocity
• Mass and velocity

An object's gravitational potential energy is dependent on the object's mass, the strength of its gravitational field, and which of the following:
(1 point)
• the temperature of the object
• the velocity of the object
• the height of the object
• the shape of the object
(1 point)
• the temperature of the object
• the velocity of the object
• the height of the object
• the shape of the object
The correct answer is the height of the object.
Gravitational potential energy is given by the formula \( PE = mgh \), where \( m \) is the mass, \( g \) is the gravitational field strength, and \( h \) is the height above a reference point.
Lucy picks up an object from the floor. How will the potential energy change if Lucy lifts the object above her head? (1 point)
• The object's potential energy will stay the same.
• The object's potential energy will decrease.
• The object's potential energy will increase.
• The object's potential energy will be zero.
• The object's potential energy will stay the same.
• The object's potential energy will decrease.
• The object's potential energy will increase.
• The object's potential energy will be zero.
The correct answer is The object's potential energy will increase.
When Lucy lifts the object from the floor to above her head, the height of the object increases, and since gravitational potential energy depends on height, the potential energy of the object will increase.
