If you have a graph of gravitational force against radius, the area under the graph between any point and the F-axis is the gravitational potential energy at this point. The area under the graph between any two points is the difference in gravitational potential energy between them .
What does a potential energy curve show?
The potential energy curve shows how much potential energy the boulder has at each position . ... The rest of its energy is kinetic energy, and you can read exactly how much kinetic energy the boulder has from the diagram — the kinetic energy is just the distance between the potential energy curve and total energy line.
What is the area under a potential energy vs position graph?
The area of a Force vs Position graph gives the work done by that force. The opposite of the area of a force vs position graph give the change in potential energy. The opposite of the slope of a potential energy vs position graph gives the force acting on that particle . a moving particle changes with its position.
Is energy the area under the curve?
Area Under the Curve. energy = power x time can be interpreted as the area under the curve : Energy = . 3 kW x 4 hours = 1.2 kWh = height (kW) x width (hrs) = area under the power curve in units of kWh.
What comes under potential energy?
To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
What is the slope of a potential energy vs position graph?
We now know that the (negative of) slope of a potential energy vs. position graph is force. The conclusion is that the equilibrium positions are the positions where the slope of the potential energy vs. position curve is zero .
What is the slope of a potential energy graph?
The negative of the slope of the potential energy curve, for a particle, equals the one-dimensional component of the conservative force on the particle . At an equilibrium point, the slope is zero and is a stable (unstable) equilibrium for a potential energy minimum (maximum).
How do you find the equilibrium position of potential energy?
Looking back at the graph of potential energy, the force can be found by looking at the slope of the potential energy graph (F=−dUdx) ( F = − d U d x ) . Since the force on either side of the fixed point points back toward the equilibrium point, the equilibrium point is called a stable equilibrium point.
How do you find the area under a graph?
The area under a curve between two points is found out by doing a definite integral between the two points. To find the area under the curve y = f(x) between x = a & x = b , integrate y = f(x) between the limits of a and b. This area can be calculated using integration with given limits.
Why is work the area under the curve?
Work as area under the curve. What does Work as area mean? If you graph the force on an object as a function of the position of that object, then the area under the curve will equal the work done on that object . ... x graph is equal to the work.”
What are the 3 main types of potential energy?
There are three main types of potential energy: elastic potential energy, gravitational potential energy, and chemical potential energy . Elastic potential energy is stored in objects that can either be stretched or compressed.
What is potential energy class 11th?
Potential energy is the energy stored within the object due to the position of the object . ... To sum up, potential energy is the energy accumulated in an object due to its location relative to some zero position. An object has gravitational potential energy if it is located at a height above (or below) the zero height.
What are 5 examples of potential energy?

- A car that is parked at the top of a hill.
- A yoyo before it is released.
- River water at the top of a waterfall.
- A book on a table before it falls.
- A child at the top of a slide.
- Ripe fruit before it falls.
What is the specific energy curve?
In open channel flow, specific energy ( e ) is the energy length , or head, relative to the channel bottom. ... It is also the fundamental relationship used in the standard step method to calculate how the depth of a flow changes over a reach from the energy gained or lost due to the slope of the channel.
How do I calculate potential energy?
Gravitational potential energy is one type of potential energy and is equal to the product of the object’s mass (m), the acceleration caused by gravity (g), and the object’s height (h) as distance from the surface of the ground (the body).
What is the potential energy of the reactants?
The potential energy measures the energy stored within the bonds and phases of the reactants and products . This potential energy is a part of the internal energy. In chemical reactions, the internal energy represents the total energy of the system and is often called enthalpy.
What part of a potential energy diagram reveals the enthalpy of reaction apex?
What part of a potential energy diagram reveals the enthalpy of reaction? The difference in potential energy between the reactants and products.
What is area under the curve statistics?
The area under (a ROC) curve is a measure of the accuracy of a quantitative diagnostic test . ... The interpretation of the AUC is: The average value of sensitivity for all possible values of specificity (Zhou, Obuchowski, McClish, 2001) .
What is the difference between the potential energy of the reactants and the potential energy of the products?
the reactants have less potential energy than do the products . Energy must be input in order to raise the particles up to the higher energy level. the reactants have more potential energy than the products have. ... Both endothermic and exothermic reactions require activation energy.
How do you calculate potential energy in simple harmonic motion?
Energy and the Simple Harmonic Oscillator. U=12kx2. U = 1 2 k x 2 . In a simple harmonic oscillator, the energy oscillates between kinetic energy of the mass K=12mv2 K = 1 2 m v 2 and potential energy U=12kx2 U = 1 2 k x 2 stored in the spring.
What is the area under the curve in physics?
The area under the curve is the magnitude of the displacement , which is equal to the distance traveled (only for constant acceleration).
What is the area under normal distribution curve?
The area under the normal distribution curve represents probability and the total area under the curve sums to one . Most of the continuous data values in a normal distribution tend to cluster around the mean, and the further a value is from the mean, the less likely it is to occur.
What does the area under AF n versus x m curve represent?
A force-displacement graph will have force (in N) on the vertical axis and displacement (in m) on the horizontal axis. ... Use the area under the graph to find the work done by the force . This is equal to the kinetic or potential energy the object gains due to the application of the force.
What does the area under velocity?
The area under a velocity-time graph is the displacement . Velocity can be negative if an object is moving backwards. The displacement can also be negative.
Which of the following method are used to determine area under curve?
There are various methods to calculating the area under a curve, for example, Rectangle Method, Trapezoidal Rule and Simpson’s Rule. ... Therefore, if we take the sum of the area of each trapezoid, given the limits, we calculate the total area under a curve. Consider the following example.
What does the area under the curve on a velocity vs time graph represent?
The area under the velocity/time curve is the total displacement . If you divide that by the change in time, you will get the average velocity.
Do all objects have potential energy?
Stored Energy. Kinetic and potential energies are found in all objects . If an object is moving, it is said to have kinetic energy (KE). Potential energy (PE) is energy that is “stored” because of the position and/or arrangement of the object.
What are the 10 types of potential energy?
- gravitational potential energy. roller coaster. waterwheel. hydroelectric power.
- electromagnetic potential energy. electric potential energy. magnetic potential energy. chemical potential energy. ...
- strong nuclear potential energy. nuclear power. nuclear weapons.
- weak nuclear potential energy. radioactive decay.
How do you explain potential energy to a child?
Potential energy is the stored energy an object has because of its position or state . A bicycle on top of a hill, a book held over your head, and a stretched spring all have potential energy.
