the girl is at the highest point in swinging and starts to come down. what describes the changes in energy as she begins do descend.
As the girl begins to descend from the highest point while swinging, there are several changes in energy that occur:
1. Potential Energy: Initially, at the highest point, the girl possesses the maximum potential energy. This potential energy is due to her height above the ground and is stored in the gravitational field. As she starts descending, her potential energy gradually decreases.
2. Kinetic Energy: As the girl starts descending, her potential energy gets converted into kinetic energy. Kinetic energy is the energy of motion, and it increases as the girl's speed increases. Therefore, as she descends, her kinetic energy begins to increase.
3. Total Mechanical Energy: The total mechanical energy of the system (including the girl and the swing) remains constant throughout the swing, neglecting any losses due to air resistance or friction. Thus, as the girl descends, her potential energy decreases, but her kinetic energy increases in a way that the total mechanical energy remains constant.
In summary, as the girl begins to descend while swinging, her potential energy decreases, her kinetic energy increases, and the total mechanical energy remains constant.
a person is riding a skateboard on a u shaped ramp. at which point does the person have the greatest potential energy?
The person riding a skateboard on a U-shaped ramp would have the greatest potential energy at the highest point of the ramp, which is generally referred to as the crest or peak. This is the point where the person is at the maximum height above the ground and thus possesses the highest potential energy.
as the bicyclist rides from right to left aw hwich of the three points if any is the picyclist potential energy incrreasting (A bottom B top C bottm)
the potential energy is increasing at point b because the bicylist is highest there
the potetial energy is incrasing at point a because the byciclist is moving fastes at that point
the potential energy is increasing at point c because the byciclist is increasing in elevation at that point
if a monkey drops a bannana off of a cliff wherr are the potential and kinetic energies of the banna equal
The potential and kinetic energies of the banana would be equal at the halfway point of its fall.
When the banana is first dropped, it begins to fall due to gravity, and its potential energy starts to convert into kinetic energy. As it falls, the potential energy decreases, while the kinetic energy increases.
At the halfway point, the banana has lost half of its initial potential energy and gained an equal amount of kinetic energy. Therefore, at this point, the potential energy and kinetic energy of the banana are equal.
After passing the halfway point, the banana continues to fall, and its kinetic energy increases, while its potential energy further decreases until it reaches its maximum kinetic energy and minimum potential energy at the bottom of the fall.
Your statement is partially correct. The potential energy of the bicyclist would increase at point B (top) because the cyclist is at the highest elevation. However, the potential energy does not increase at point A (bottom) or point C (bottom).
At point A (bottom), the potential energy of the bicyclist is at its minimum because the cyclist is at the lowest elevation. As the cyclist moves up the ramp towards point B, their potential energy increases.
At point C (bottom), the potential energy of the bicyclist remains constant or possibly decreases slightly if there are any energy losses due to factors like friction or air resistance. This is because the cyclist is already at a lower elevation compared to point B, so there is less potential energy.
Therefore, the potential energy increases at point B (top) as the bicyclist is at the highest elevation. At points A (bottom) and C (bottom), the potential energy either remains constant or decreases.
