Is a real car a kinetic energy?
No. A real car IS not kinetic energy, but it HAS kinetic energy.No. A real car IS not kinetic energy, but it HAS kinetic energy.No. A real car IS not kinetic energy, but it HAS kinetic energy.No. A real car IS not kinetic energy, but it HAS kinetic energy.
An object that has NO kinetic energy must be?
An object with zero kinetic energy is at rest. However, since reference frames are relative, the calculation of kinetic energy is done with reference to an arbitrary point.
What are possible reasons for any difference between the work done and kinetic energy?
kinetic is not a potential energy because kinetic energy is made of movement but potential energies are stored but can be used
When you hold a ball above the ground does it have kinetic energy?
Yes and no. When the ball is at its highest point, it is storing potential energy. when it is moving back down, the potential energy turns into kinetic energy, and so forth. But when the ball is done bouncing, it doesn't technically "store" energy.
What type of energy does an electrical fan produce?
Yes, because it is not 100 % efficient at converting electrical energy into kinetic energy.
If work done on an object is equal to object's change in kinetic energy this the state of?
the Work-Energy Theorem states the work done is equal to the change in kinetic energy.
The kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf?
no, but the POTENTIAL energy may equal the work done to life the book to the shelf
Is t true the kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf?
no
True or false the kinetic energy of a book shelf is equal to the work done to lift the book to the shelf?
false

The net work done by all the forces acting on an object is equal to the change in the object's kinetic energy?
That sounded plausible at first, but it's not true. The work you put into the objectis equal to the change in its total energy, but that could be in the form of kinetic,potential, chemical, any other form, or some of it going to each of several forms.
Its kinetic energy and its potential energy be equal?
Yes, however it is very unlikely in day to day life. It could be done if the nessesary calcualtions are perfromed and an object is dropped from a precise height so that in a moment of time, its gravitational potential energy is equal to it's current kinetic energy. An even simpler way of making these energies equal is driving a car over a bridge of a known height and keeping the car at such a speed that its Ke is equal to it's GPe so that Ke=GPe

How do you find work given mass initial velocity and final velocity?
We assume you mean the work done in order to change the velocity of the moving mass.Easiest way is to calculate the change in the kinetic energy of the moving mass, and realizethat it's equal to the amount of work either put into the motion of the mass or taken out of it.Initial kinetic energy = 1/2 m Vi2Final kinetic energy = 1/2 m Vf2Change in kinetic energy = 1/2 m ( Vf2 - Vi2)
What type of energy does an electrical fan produce?
Yes, because it is not 100 % efficient at converting electrical energy into kinetic energy.
