What is the relationship between force and energy?
energy equals force times distance
thanks for the help
one other thing...
i know that energy is conserved (the total amount in a closed system is constant), but why is it incorrect to say that force is conserved?
Usually when we say that something is conserved we mean that it is constant with respect to time. The total energy of a closed system is conserved because that level of energy never changes. There are certainly situations where force might be conserved (such as the weight of a book sitting on a table), but the types of cases where this would occur would be far too restrictive to put into a general theorem.
