Elastic potential energy
is the energy stored in elastic materials as the result of their stretching or compressing. Elastic potential energy can be stored in rubber bands, bungee chords, trampolines, springs, an arrow drawn into a bow, etc.
What is potential energy associated with objects called?
Gravitational potential energy
is energy in an object that is held in a vertical position, due to the force of gravity working to pull it down. The amount of gravitational potential energy an object has depends on its height and mass.
What is potential energy stretched?
Elastic potential energy is the potential energy
stored by stretching
or compressing an elastic object by an external force such as the stretching of a spring. It is equal to the work done to stretch the spring which depends on the spring constant k and the distance stretched.
What is the name of energy given to objects that are stretched?
Elastic potential energy
is stored in stretched or squashed materials.
What is the potential energy of a stretched string?
Hooke’s Law, F = -kx, where F is the force and x is the elongation. The energy stored can be found from integrating by substituting for force, and we find, The energy stored
= kx2/2
, where x is the final elongation.
What are 4 examples of potential energy?
- A raised weight.
- Water that is behind a dam.
- A car that is parked at the top of a hill.
- A yoyo before it is released.
- River water at the top of a waterfall.
- A book on a table before it falls.
- A child at the top of a slide.
- Ripe fruit before it falls.
What are the 7 types of potential energy?
- Gravitational potential energy.
- Elastic potential energy.
- Nuclear energy.
- Chemical energy.
- Electric potential energy.
What are three examples of elastic potential energy?
- The coil spring of a wind-up clock.
- An archer’s stretched bow.
- A bent diving board, just before a divers jump.
- The twisted rubber band which powers a toy airplane.
- A bouncy ball, compressed at the moment it bounces off a brick wall.
Does a stretched spring have potential energy?
As soon as the spring is stretched or compressed, there is
positive potential energy stored
in the spring.
What are the 8 different types of energy?
The different types of energy include
thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy
.
What are 5 types of potential energy?
Systems of objects ranging from atoms to planets can be arranged in many ways, resulting in many forms of potential energy:
chemical, elastic, electrical (electromagnetic), gravitational, nuclear, and thermal energy
.
What are the 7 energy stores?
- magnetic.
- internal (thermal)
- chemical.
- kinetic.
- electrostatic.
- elastic potential.
- gravitational potential.
- nuclear.
What are the 4 energy transfers?
- Mechanically – By the action of a force.
- Electrically – By an electrical current.
- By radiation – By Light waves or Sound waves.
- By heating – By conduction, convection or radiation.
Why is energy stored in a wire?
In order to stretch a wire,
certain work must be done against restoring force
. This work done is stored in the form of potential energy (U) of the stretched wire. This work done is equal to the potential energy stored (U). …
How do you prove work energy theorem?
- The work W done by the net force on a particle equals the change in the particle’s kinetic energy KE: W=ΔKE=12mv2f−12mv2i W = Δ KE = 1 2 mv f 2 − 1 2 mv i 2 .
- The work-energy theorem can be derived from Newton’s second law.
- Work transfers energy from one place to another or one form to another.
What is the formula for calculating elastic potential energy?
The spring constant is the measure of stiffness of a spring. Hooke’s law gives us the force we need to find elastic potential energy. Looking at a graph of force versus displacement, we can find that the formula for elastic potential energy is
PE = 1/2(kx^2).
