Does pushing a pen off a desk converts potential energy to kinetic energy?
Yes. When the pen is sitting on the desk, it has the most potential energy. Once you move the pen, its potential energy is transformed into kinetic energy.
A pencil resting on a desk is an example of which type of energy?
Potential energy
Which form of energy is represented by a book lying on a desk which form of energy is represented by book falling off a desk?
Lying on a desk: Potential energy Falling off a desk: Kinetic Energy
Why when you push an object across a desk is the work done not equal to the change in gravitational potential energy?
The gravitational potential energy does not change if the desk is horizontal. The work done is in overcoming the friction between the object and the desk.
A pencil resting on a desk is an example of what kind of energy?
Potential.

What difference between kinetic energy and potential energy?
Kinetic energy is related to movement (a faster object has more kinetic energy); potential energy is related to position (higher up, objects have more potential energy).Examples:A leopard waiting in a tree, motionless, waiting to jump on you has potential energy.A leopard leaping on you has kinetic energy, or energy of movement.Kinetic energy is the energy that an object has when it is in motion. Potential energy is the energy that an object has when it is at rest. For example, a book sitting on a desk has maximum potential energy and zero kinetic energy. If the book falls off of the desk, then its kinetic energy increases and its potential energy decreases.

What type of energy does a book have if it is on the edge of a desk?
It has gravitational potential energy, as well as chemical energy.
Why is putting a book bag on a desk a form of energy?
A book bag on a desk has potential energy. That potential energy is due to its height above the ground. That potential energy is given by the formula Ep = mgh, where m is the object's mass, g is the acceleration due to gravity, and h is the height.
List 5 examples of potential energy?
Potential Energy: a book at your desk a cartolina on the wall a table on the ground books on your bag a pen on your pen holder
What happens to the potential engrgy of a bookas it dops from a desk to a desk to the floor?
Converted from potential energy to kinetic energy during the fall, then a small amount of energy is converted into sound and pretty much everything else is converted to heat. If the floor was soft (carpet for example) there would be a small amount of energy converted back to potential energy as the fibres were compressed and then this would be converted into kinetic energy and the cycle would repeat until equilibrium was attained.
How could you increase the energy of an object resting on a desk?
There are different types of energy. You can increase the gravitational potential energy by raising the object. You can increase its thermal energy by heating it up.
What energy transformation occurs in a pencil sharpener?
mechanical energy
