What is an example of a object with elastic potential energy?
Rubber band. Bungy jump cord, anything that can stretch and then return to it's normal state.
How do you know an object has energy?
Usually it means the object has gained height. It could also happen if the object is moved to a planet with higher gravity. Potential NRG also occurs when a positively charged object moves into an area of higher potential in a electric or magnetic field, or when a negatively charged object moves into an area of lower potential in an electric or magnetic field.
What is an example of potential enrgy?
Examples of potential energy : 1. An object raised above the ground acquires potential energy equal to the work done against the force of gravity; the energy is released as kinetic energy when it falls back to the ground. 2. Similarly, a stretched spring has stored potential energy that is released when the spring is returned to its unstretched state.
What is the main purpose of a heat pad?
A heat pad is a chemical apparatus that transforms stored state energy into heat when stimulated. This is often achieved through the use of certain salt solutions stored in a metastable state.
State the two factors that determine the amount of work done on an object?
Energy and pressure
What is elastic strain energy?
Potential Elastic Energy.
What is an example of a object with elastic potential energy?
Rubber band. Bungy jump cord, anything that can stretch and then return to it's normal state.
Explain the ideas of potential and kinetic energy using a rubber band as your example?
When you stretch the rubber band you are doing work and energy is stored in the elastic, this is potential energy. When you release the band, the potential turns into kinetic and you have movement, until the elastic has returned to its unstressed original state. Im bored humor me
What energy is stored in a slingshots surgical tubing?
Since the energy stored elastically by an object is represented by E = 0.5kx^2 a simple calculation can be done to see how much energy is being stored by your slingshot on any given pull: The x value represents the distortion in meters (ie. the difference between the length of the band when it is in its resting state, and its length when it is being pulled). The k value is the elastic constant for the surgical tubing. This value can be looked up in a chart or table, or can be calculated experimentally (with the use of the equation: F = kx, again where k and x represent the elastic constant, and deformation, respectively). Once you have your values, simply substitute them into the equation and solve. The calculated energy stored, will have its units in Joules (J).
State hook's law?
The extension of an elastic object is directly proportional to the force applied
When is the kinetic energy transferred from object to object?
kinetic Energy. Energy is transferred from one object to another when a reaction takes place. Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. For the blue ball to move to the position of the green ball, energy must be given to the blue ball.
What state of matter has the most energy stored as interaction energy?
Solid
What change of state and what energy changes occur when water freezes?
the state change is from liquid to solid and the energy change is cold energy to heat energy
What is energy that is stored or released during a change of state of water?
latent heat
What is dynamic energy?
is the state of an object of being in motion or movement
If work done on an object is equal to object's change in kinetic energy this the state of?
the Work-Energy Theorem states the work done is equal to the change in kinetic energy.
How much nuclear energy has israel stored all together?
This is an Israeli state secret
