Conservation of Energy graph help

In summary, a graph of potential energy versus kinetic energy should have a linear shape with a downwards slope of 45 degrees, assuming no losses and constant total energy. If the graph is going up instead of down, it is likely that the direction of potential energy has been assigned incorrectly. When an object is in a vacuum and motionless at a certain height, its potential energy can be calculated as mgh. As the object falls, potential energy decreases and kinetic energy increases. Therefore, if the graph is going up with a large slope, the negative effect of gravity should be included in the calculations for potential energy.

What should a graph of potential energy versus kinetic energy look like. My graph is linear but I'm pretty sure it should look like a parabola.

Assuming no losses, then total energy is a constant, and

potential_energy + kinetic_energy = total_energy

So the graph of potential versus kinetic energy is a linear graph with a downwards slope of 45 degrees.

What does it mean if my graph is going up instead of down?

Most likely that you've assigned the wrong direction to potential energy. Assume some object is in a vacuum, motionless, at some height "h". The potential energy = m g h. If you let the object fall, potential energy decreases, and kinetic energy increases.

My graph is going upward with a large slope. Am I suppose to include the negative gravity in my calculations for potential energy?
 

FAQ: Conservation of Energy graph help

What is a conservation of energy graph?

A conservation of energy graph is a visual representation of the principle of energy conservation, which states that energy cannot be created or destroyed, only transformed from one form to another. It shows the distribution and transformation of different types of energy in a system over time.

What types of energy are typically included in a conservation of energy graph?

A conservation of energy graph typically includes kinetic energy, potential energy, thermal energy, and any other relevant forms of energy that are involved in the system being studied.

How is the total energy represented in a conservation of energy graph?

The total energy of a system is represented by the total height of the graph, which remains constant over time. This is because of the principle of energy conservation, which states that the total energy in a closed system remains constant.

What does the slope of a conservation of energy graph represent?

The slope of a conservation of energy graph represents the rate at which energy is being transformed or transferred within the system. A steeper slope indicates a higher rate of energy transformation, while a flatter slope indicates a slower rate.

How can a conservation of energy graph be used to analyze a system?

A conservation of energy graph can be used to analyze a system by identifying the different types of energy present, tracking how they are transformed or transferred, and determining the overall energy balance. It can also be used to identify any inefficiencies or losses in the system.
