What is the gravitational potential energy equation?
Gravitational potential energy = Mass x gravity x heightTherefore, an object at ground level is 0 meters above the ground, thus having no potential energy.PE = mghm = massg = gravitational accelerationh = height
Does gravitational acceleration calculate potential energy?
Gravitational potential energy describes how much energy a body has in store by virtue of having been elevated to a specific height. The formula to calculate gravitational potential energy is:.U = mgh.Where:U is the potential energym is the mass of the objectg is the acceleration due to gravity, andh is the height the object will fall if dropped.
What are life examples where positive and negative integers can be used?
Altitudes above vs. below sea level; having money vs. owing money; moving in one direction vs. moving in the opposite direction; being above and below a certain reference level (for calculating potential energy). In general, in many situations where you have two opposites, one can be called "positive", the other "negative".
What will be the weight in kg of 1 liter of furnace oil having specific gravity of 0.9655?
Mass is measured in kilograms, not weight. The mass of the furnace oil will be 0.9655 kg. If you do not know the difference between weight and mass, consider the following: You have the same amount of material in you whether you are in earth, in mid space or on the moon. That is your mass. You also have a certain amount of weight on earth, which is the effect of the earth's gravitational force acting on your mass. On the moon, the gravitational force is only a sixth as strong and your weight will be only a sixth as much as on earth. In outer space, there may be no gravitational force in which case your weight will be 0. Thus your mass is something that is an intrinsic property of you (at least, of your body) while your weight is largely dependent on the gravitational force acting on you.
Is Weight is the measure of force and mass?
Weight is a measure of the gravitational pull for a mass , such that a mass of 1 Kg is having a weight of 10 Newton . So weight is a downward force measured in Newtons . Weight ( in N ) = Mass ( in Kg ) × Gravity ( usually 10N/Kg )
What is the gravitational potential energy equation?
Gravitational potential energy = Mass x gravity x heightTherefore, an object at ground level is 0 meters above the ground, thus having no potential energy.PE = mghm = massg = gravitational accelerationh = height

Why does a 70-kg stone have more gravitational potential energy than a 50-kg stone?
it is heavier therefore having higher gravitational pull
What are the other uses of potential energy?
it is used in generating electricity when water is raised to a height to make it fall on a turbine it is having potential energy stored in it.It has many other forms as elastic ,gravitational,vibrational potential energy.
Which of these would have the greatest potential energy?
the object that has the most potential energy is whatever is not moving but is ready to move like flinging a rubber band let's say you holding it back now it has energy stored in it then once you let go and it flings it has kinetic energy which is a different story but that is my answer F.Y.I kinetic energy is when it energy is being used and dies down back into potential .......... get it now ;);0
How do pontential energy and kinectic energy compare?
object having height possess potential energy.Object having motion possess kinetic energy.
What is energy stored in an object?
Potential energy is work done against a conservative force, such as gravity. You might say it is stored in the force field or force fields. It is often convenient to think of an object (a raised stone, for example) as "having" a certain amount of potential energy, but it is probably more accurate do consider the energy as being in the RELATIONSHIP between the two objects. If the rock and planet Earth are farther apart, there is more potential energy; if they are nearer, there is less potential energy. Just by observing the rock or Earth, you won't notice any energy (like heat, or movement); you have to observe the RELATIONSHIP between the two to conclude that there is potential energy.
Why total electronic energy is negative?
In the case of potential energy, what matters is the difference in potential energy. Any "absolute potential energy" is an arbitrary definition. If you define a certain reference height as "zero height" and therefore "zero potential energy", anything above that would have a positive potential energy (as compared to the reference height), anything lower would have a negative potential energy. In Astronomy, for conveniencen, two objects at an infinite distance are often defined as having zero potential energy - thus, by definition, anything closer by would have a negative potential energy.In the case of potential energy, what matters is the difference in potential energy.

What does it mean if matter that was still begins to move?
it went from having potential to kinetic energy
What is the connection between kinetic energy and potential energy?
When potential energy and kinetic energy are combined it is called mechanical energy. Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).
Can something have kinetic energy without having potential energy?
Sure. Picture a squash ball rolling across a basketball court.
Potential energy exists when an object is affected by this Gravity and magnetism are examples of this?
having it with a girl/boy
