When you perform work on an object do you increase the energy of the object?

Generally yes, but it really depends on the specific situation.
-- If the work is done to lift the object, then the object's potential energy is increased.
-- If the work is done to accelerate the object, then the object's kinetic energy is increased.
-- If the work is done to move the object against friction, then the energy supplied
is dissipated, and the object's energy may or may not change, depending on whether
or not it is somewhat heated by the dissipation.

A net force of 22 N accelerates a 4-kg mass over a distance of 18 m. What is the work done by this net force What is the increase in kinetic energy of the mass?
Work done by a force (W) = Force (F) x distance (m) W = 22 x 18 = 396 Joules According to the law of conservation of Energy, the total energy of a closed system is constant, but can change from one type to another. Therefore, the work given to the object must be converted into the kinetic energy of the object. So, Increase in Kinetic energy = work done = 396 Joules
If work is don adiabatically on a system will the internal energy increase or decrease?
If work is done adiabatically on a system, the internal energy will increase. This is because adiabatic processes do not involve the exchange of heat with the surroundings, so any work done on the system will directly contribute to an increase in its internal energy.
If a raised object has potential energy does it have more if you lift it higher?
Yes. The potential energy of an object is E=mgh where m=mass, g=acceleration of gravity (9.8 m/s^2) and h is the height of an object above a reference point. So, if two objects (on the same planet) have the same mass, the one that is higher will have the larger potential energy. Another way to think of this is that in lifting an object higher you do work on that object. That work is converted into it's potential energy. Whenever you do work you change the energy of the object.
What is the transfer of energy that causes an object to move in the direction of the force called?
The transfer of energy that causes an object to move in the direction of the force is called work.
What is the relationship among work and heat and energy?
Work is usually used for transfer of energy. If you transfer energy to an object, you "do work" on the object.Heat is simply one type of energy.Further AnswerWork (W) describes changing one form of energy into another. Heat (Q) describes energy in transit from a warmer body to a cooler body. So change in energy is the difference between work and heat.change of energy = W - Q
When you perform work on an object you increase the energy of the object. true or false?
true
When you perform work on an object you increase the energy of the object true or false?
true
When you perform work on an object on an object you increases the energy of the object?
true
When you perform work on an object do you decrease the energy of the object?
Yes.

When you do positive work on an object you?
increase the object's energy
What is added to an object when work is done on it?
In that case, the object's energy should increase.
Does magnet force perform work?
It exerts magnetic energy to push or pull an object
When negative work is done on a moving object it's kenetic energy?
When negative work is done on the object, the object's energy decreases. This MAY be kinetic energy, but some other form of energy may increase instead, for example, potential energy or heat energy.
When you work on an object you increase the what of the object?
It could be many things, possibly energy, or even value, or even the probability of it breaking.
What happens to the kinetic energy of a moving object if the network done is positive?
That really depends on the situation. Work done on an object may increase its kinetic energy; but it may also just increase its potential energy (e.g., when pushing something upwards against the force of gravity).
When work is done what happens with the energy?
"Work" refers to a transfer of mechanical energy. There is work when you apply a force over a certain distance. What happens to the energy depends on the situation - it may be absorbed by friction (and converted to heat), it may speed an object up (kinetic energy), it may increase the receiving object's potential energy, etc.
