I lift a book from the floor and place it on my desk.
The amount of work I do on the book is the amount by which
its gravitational potential energy has increased . . .
M G H
where 'M' = mass of the book, 'G' = acceleration of gravity, 'H' = height of the table above the floor.
By the way, when I increased the energy of the book, I also increased its mass. The change in mass is
dM = dE / c2
What else can I help you with?
What happen to the potential energy of an object as it falls?
As an object falls, its potential energy decreases and is transformed into kinetic energy. This is due to the force of gravity doing work on the object as it moves downwards. The potential energy is converted into kinetic energy, which increases the object's speed as it falls.
What is the diffrence between kinetic energy and potential energy?
Kinetic energy is the energy an object possesses due to its motion, while potential energy is the energy an object has due to its position or state. Kinetic energy depends on the object's mass and velocity, while potential energy depends on factors like height, position, or condition of the object.
How does kinetic energy and potential energy switch?
work=change in kinetic energy, doing work on an object by moving it up increases that object's potential energy because it has the POTENTIAL to fall due to gravity. kinetic energy is lost in the movement of the object. However, throughout an entire closed system, the total energy in joules (or kinetic enery plus potential energy) does remain constant. this is useful because the initial energy and the final energy most be equal, and if thats true, then initial kinetic energy plus initial potential energy must equal final kinetic energy plus final potential energy. does that help?
Is a tractor pulling plow kinetic energy or potential energy?
The tractor pulling the plow is an example of kinetic energy because it is in motion and doing work by moving the plow through the soil. Potential energy is associated with stored energy due to an object's position or condition, such as the plow being lifted up and not yet in motion.
What is the difference between chemical energy and knetic energy?
Chemical energy is stored in the bonds of molecules and is released during a chemical reaction. Kinetic energy is the energy of motion, possessed by an object in motion. In other words, chemical energy is potential energy stored in chemical bonds, while kinetic energy is the energy of movement.
When you increase the height of a ramp which increases the angle does the efficiency for kinetic energy increase of decrease?
When you increase the height of a ramp, the efficiency for kinetic energy decreases because you are doing work against gravity to lift the object higher. This means less of the initial potential energy is converted into kinetic energy compared to when the ramp is lower.
What happen to the potential energy of an object as it falls?
As an object falls, its potential energy decreases and is transformed into kinetic energy. This is due to the force of gravity doing work on the object as it moves downwards. The potential energy is converted into kinetic energy, which increases the object's speed as it falls.
Which of the following has kinetic energy?
An object in motion, such as a moving car or a swinging pendulum, has kinetic energy. It is the energy an object possesses due to its motion.
Why does the potential energy decrease when something falls or is dropped?
When something falls or is dropped, its potential energy decreases because it is being converted into kinetic energy due to gravity. As the object moves closer to the Earth's surface, gravitational force is doing work on it, causing a reduction in potential energy and an increase in kinetic energy.
What is the relationship between kinetic energy and work?
Relationship between work and kinetic energy. Work is defined as the result of a force moving an object a distance and is stated by the equation W=Fd. But the result of the force being applied on the object also means that the object is moving with some given velocity, according to the equation for force as F=ma. From those two equations, it can be shown that work is equivalent to kinetic energy Kinetic Energy =1/2mv2
What is the diffrence between kinetic energy and potential energy?
Kinetic energy is the energy an object possesses due to its motion, while potential energy is the energy an object has due to its position or state. Kinetic energy depends on the object's mass and velocity, while potential energy depends on factors like height, position, or condition of the object.

The energy you give to an object when you use a force that goes against the force of gravity?
The energy you give to an object when you use a force that goes against the force of gravity is called gravitational potential energy. As you lift an object against gravity, you are doing work on it, which results in an increase in potential energy due to its height above the ground. This potential energy can be converted back into kinetic energy if the object is released and falls.
Doing work on an object increases the object's kinetic?
velocity increases
What is the relationship between the kinetic energy and the physical state of the substance they compose?
Kinetic energy is energy of matter. The kinetic is doing work. Tempature is measured of average energy of motion, particles of matter. The physical is pretty much doing the same thing as the kinetic. They both are doing work.
How can doing work on a object increase its potential energy?
When work is done on an object by applying a force over a distance, the object gains potential energy. For example, lifting an object against gravity increases its height and potential energy due to the work done in lifting it. This increase in potential energy is a result of the energy transferred to the object from the external force applied to it.
Energy doing a job is called?
The energy used to do a job is called work. Work is a measure of the energy transferred when a force acts on an object and causes it to move a certain distance.
