## How much elastic potential energy is stored in the spring?

The elastic potential energy of a spring is one half the product of its spring constant multiplied by the square of its extension or compression. or Page 2 6/3/14 2 Energy may be stored in a system when work is done on the system. When you apply a force to a spring, it deforms.

## Where does the spring have maximum elastic potential energy?

When the glider is at position A, the spring is stretched the greatest distance and the elastic potential energy is a maximum. A similar statement can be made for position E. At position E, the spring is compressed the most and the elastic potential energy at this location is also a maximum.

## What is the formula for maximum potential energy?

The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

## How does mass affect kinetic energy of a pendulum?

Mass and the Period Your investigations should have found that mass does not affect the period of a pendulum. One reason to explain this is using conservation of energy. If we examine the equations for conservation of energy in a pendulum system we find that mass cancels out of the equations.

## Why does the pendulum eventually stop swinging where does the energy go?

A pendulum stops oscillating because it loses energy when it is converted into heat. Even without air friction, the friction which exists with the point around which the pendulum rotates causes the system to lose kinetic energy and eventually stop.

## Why would a pendulum stop swinging?

The main reason the pendulums stop is due to air friction and the friction at the point of rotation. To see a pendulum that removes one of these sources of friction, you can see a Coriolis force clock. These are pendulums that swing but instead of being on a pivot point, they are held up magnetically.

## What transformation of energy happens in the swinging pendulum?

As a pendulum swings, its potential energy converts to kinetic and back to potential. Recall the concept of conservation of energy—that energy may change its form, but have no net change to the amount of energy.
