What two things do you need to increase the kinetic energy of an object?
speed and potential energy
Is potential energy measured in consumption or expenditure?
Potential energy is stored energy. It has nothing to do with consuming or using energy - although you need to use some other energy to increase an object's potential energy. For example, in the case of gravitational potential energy, an object above ground level (or any other reference level chosen) has a positive potential energy, while an object below ground level has a negative potential energy.
How can potential energy be increased and decreased?
Potential energy is pretty much the potential for kinetic energy. The less kinetic energy there is, the more potential... On the other hand, if you need gravitational potential energy, then the higher the object is placed above the ground, the more GPE it has.
A object has one joule of potential energy explain what does it means?
We know that energy is defined as the ability to do work.So an object has one joule of potential energy means that the body has capability to do a work of one joule. We may say that the object with 1 joule of potential energy is the force field and our work is stored in displacing the object against the field
What are the effects of kinetic energy?
You need to rethink your question. Kinetic energy is the energy that an object possesses because of its motion. Exactly what is it that you want to know?
What two things do potential and kinetic energy need to gain more energy?
Well, basically, the higher an object is above the ground, the more potential energy it has. For kinetic energy, the amount of energy depends on the amount of force.
How do you find kinetic energy using mass height potential energy and acceleration due to gravity?
I assume the situation you have in mind is an object falling from a certain height. All you need from the information you listed is the potential energy. When the object falls, once it is close to the ground all the potential energy will be converted into kinetic energy. This assumes that air resistance is negligible.
When an object is lifted 12 feet off the ground it gains a certain amount of potential energy if the same object is lifted 36 feet off the ground its potential energy is?
The potential energy of an object can be calculated using the simple formula Potential Energy = mass*acceleration due to gravity*distance above ground. For simplification, we can call the mass m and the acceleration g. Using these values, the object will have a potential energy of 12m*g when it is 12 feet off the ground. When it is 24 feet off the ground, it will have an energy of 24*m*g. This is nothing more than twice the value we calculated before, so we can say that the object's potential energy at 24 feet is twice its potential energy at 12 feet. In order to give an exact value, we would need to know the mass of the object as well.
Does everyhting have energy?
Basically yes. There are different types of energy; for example: * Kinetic energy: Every moving object has kinetic energy. Whether an object is moving or not depends on the reference frame you choose. * Gravitational potential energy: Once again, you need to choose a reference point - or actually, a reference height in this case. Anything above the chosen reference height will have positive potential energy; anything below it, negative potential energy. * Heat energy: Since you can't cool any object to absolute zero, any object will have at least some heat energy.
What do you need to know in order to get an objects gravitational potential energy?
You need to have a weight and the mass of an object then you use the formula f=w=mg
When does an object have more mechanical energy than another object?
"Mechanical energy" is basically the sum of potential energy, and kinetic energy - thus, an object has more mechanical energy than another one when this sum is greater. You may just need to calculate these energies and add them up, to find out in specific cases.
Does everything need energy to move?
Newton's laws of motion apply here: things only change velocity when a force is acting upon them. While objects that are moving have (potential) kinetic energy, no extra energy is required to keep them moving: energy would be required to change their motion.
