How does increasing the amount of stored energy affect the amount of kinetic energy when an object is released?

Answer 1

The "stored energy", or potential energy, will be converted to kinetic energy.

Example:

Let U = gravitational potential energy, K = kinetic energy

U = mgh, where m is mass, g is theaccelerationdue to gravity, h is the height

(there are other types of potential energy, but this is the most common example)

K = 1/2mv2, where v is velocity

Set U equal to K, because that potential energy will be converted to kinetic energy, minus any other factors that "steal" energy (i.e., friction):

U = K

mgh = 1/2mv2 <-- masses cancel

gh = 1/2v2

The left side of the equation represents stored energy. The right side represents kinetic energy. If we increase the left side by a factor of A, we must increase the right side by a factor of A as well (it's just an algebraic step):

A(gh) = A(1/2v2)

So it should be visible, that if you if you increase potential energy, you also increase kinetic energy (by the same proportion).

Answer 2

Increasing the amount of stored energy in an object will generally increase the potential for kinetic energy when the object is released. This can result in the object moving faster or having greater kinetic energy when the stored energy is converted into motion.

Answer 3

Some of the available energy is converted to heat by friction, so the amount of useful work done is reduced by friction.

Answer 4

The Kinetic Energy Will Decrease
