An object's gravitational potential energy is dependent on the objeot's mass, the strength of its gravitational field, and which of the following: (1 poird) © the velocity of the object
The height of the object
Which factors determine the potential energy of an object?
The potential energy of an object is determined by three factors:
1. Mass of the object: The larger the mass of the object, the greater its potential energy.
2. Height or position of the object: The higher the object is lifted or raised, the greater its potential energy.
3. Strength of the gravitational field: The stronger the gravitational field, the greater the potential energy of the object in that field.
Which object has the most potential energy?
Object C
Object B
Object A

To determine which object has the most potential energy, we need more information about the objects. Factors such as mass, height, and the strength of the gravitational field should be taken into account. Without these details, it is not possible to determine which object has the most potential energy.
15lb at 1 foot off the ground
8lb at 2 feet off the ground
15lb at 2 feet off the ground
To compare the potential energy of the given objects, we need to calculate the potential energy for each object.
The formula for gravitational potential energy is: Potential Energy = mass * height * acceleration due to gravity
Here, the acceleration due to gravity is approximately 9.8 m/s^2 or 32.2 ft/s^2.
Object A:
Mass = 15 lb
Height = 1 ft
Potential Energy (A) = 15 lb * 1 ft * 32.2 ft/s^2 ≈ 482.25 ft-lb
Object B:
Mass = 8 lb
Height = 2 ft
Potential Energy (B) = 8 lb * 2 ft * 32.2 ft/s^2 ≈ 515.2 ft-lb
Object C:
Mass = 15 lb
Height = 2 ft
Potential Energy (C) = 15 lb * 2 ft * 32.2 ft/s^2 ≈ 964.5 ft-lb
Comparing the potential energies, we can conclude that Object C has the most potential energy with approximately 964.5 ft-lb.
Lucy picks up an object from the floor. How will the potential energy change if Lucy lifts the object above her head? (1 point)
If Lucy lifts the object above her head, the potential energy of the object will increase. This is because the height of the object from the ground has increased. The potential energy of an object is directly proportional to its height above a reference point, in this case, the ground. As the height increases, so does the potential energy.
Mhich of the graphs shows the relationship between an object's gravitational potential energy and the object's height above the ground? (1 point)
As an AI text-based model, I am unable to directly view or interpret graphs. However, I can describe the relationship between an object's gravitational potential energy and its height above the ground.
The relationship between an object's gravitational potential energy and its height above the ground is directly proportional. As the height of the object increases, the gravitational potential energy also increases. This relationship can be represented by a linear graph, where the y-axis represents the gravitational potential energy and the x-axis represents the height above the ground.
Imagine a graph with the y-axis representing gravitational potential energy and the x-axis representing height. The graph would start from the origin and slope upwards, indicating that as the height increases, the potential energy also increases. Therefore, the correct graph should show an upward linear relationship between potential energy and height.
