What else can I help you with?
What type of energy exists in a ball sitting on top of a hill?
kinetic energy
What is energy potential measured in?
Potential energy can't be measured directly but can be calculated in between two states. Potential energy is also sometimes called as the mechanical energy or stored energy. Every object or body has the ability to have potential energy by different means. Springs carry potential energy when it is compressed or stretched, and when released, all that potential will turn to kinetic energy because the body gains motion. Potential energy always changes into kinetic energy again by different means. Potential energy is calculated by using this expression. Ep = mgh, where m= mass, g= gravity if the body is at height, h= the height.
A 5 kg book falls from a shelf. If it lands with a speed of 5.7 ms from what height did it fall?
Here is one way to solve it:* Calculate the kinetic energy related to this speed. * Assume that no mechanical energy was lost; i.e., calculate the height required to get the same gravitational potential energy. That is, write the equation for gravitational potential energy, replace the numbers you know (including the energy you just calculated in the previous point), and calculate the height. Note that the result does not depend on the mass of the falling object.
Will a ball bounce higher if it is thrown to the ground at different heights using the same force?
No. The greater the height, the greater the potential energy. PE = m•g•h, where m is mass in kg, g is 9.8m/s2, and h is height in meters.
The amount of useable energy decreases when?
The quality of energy decreases when you use it due to the second law of thermodynamics. Essentially, the energy spent from various reactions is processed, which reduces the amount of work needed to extract it.
What is the equation of potential energy?
The equation for gravitational potential energy is: Potential Energy = mass x gravity x height. For elastic potential energy, the equation is: Potential Energy = 0.5 x spring constant x displacement squared.
What is the equation to get an objects gravitational potential energy?
The equation to calculate an object's gravitational potential energy is U = mgh, where U is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above a reference point.
What is The equation for potential energy in science?
The equation for gravitational potential energy is PE = mgh, where m is the mass of an object, g is the acceleration due to gravity (approximately 9.81 m/s^2 on Earth), and h is the height of the object above a reference point. The unit for potential energy is joules.
What is the equation for calculating gravitational potential energy on the Earth?
The equation for calculating gravitational potential energy on Earth is PE = mgh, where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity (9.81 m/s^2 on Earth), and h is the height of the object above a reference point.
What is the equation for calculating an object's gravitational potential energy?
The equation to calculate an object's gravitation potential energy is: PE=MGH where: PE is gravitational potential energy M is the objects mass G is the acceleration due to the gravitational pull of the Earth on its surface ( 9.8 m/s2) H is the height from the location that would give it zero potentional energy (generally the ground)
How does potential energy vary height?
Potential energy increases with height. The higher an object is lifted, the more potential energy it has due to its higher position in the gravitational field. The equation for gravitational potential energy is P.E. = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height.
Which of the following is the equation for gravitional potential energy?
PE for gravitation = mgh Potential Energy is measured in Joules m = mass in kilograms g = acceleration due to gravity is 9.8m/s2 h = height from "zero" in metres/meters
What Potential energy results from the or position of an object?
The potential energy that results from the "or" position of an object is gravitational potential energy. It is determined by the object's position in a gravitational field, with the potential energy increasing as the object is raised to a higher altitude. This potential energy can be calculated using the equation: PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the reference point.
Does velocity affect an object's potential energy?
No. The equation for potential energy is PE = m•g•h, where m is mass in kg, gis 9.8m/s2, and h is height in meters. Potential energy is the energy an object has due to its position. Velocity is not a factor in determining potential energy.
You can calculate gravitational potential energy by using the equation?
PE = mgh (potential energy = mass x gravity x height). In SI units, mass would be in kilograms, gravity (on Earth) is 9.8 meters/second2, and height is in meters. The resulting energy is in Joules.
How do you measure a dropped ball's potential energy?
When a ball is dropped, it no longer has potential energy. Before it drops, you can calculate the potential energy (= mgh); to actually measure this, you would have to measure the force, and multiply that by the distance.
What is the equation for potiential energy?
There are two kinds of potential energy: Gravitational Potential Energy and Elastic Potential Energy. Their formula's are: * Gravitational Potential Energy: Ep = m x g x h Ep = mass x gravity x height * Elastic Potential Energy: Ep = 1/2 x k x x^2 Ep = 0.5 x elastic constant x extention or compression squared
