What is elastic PE in physics?

What is elastic PE in physics?

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.

How do you calculate PE in physics?

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 do you calculate elastic power?

Energy stored in a spring

  1. Work is done when a spring is extended or compressed . Elastic potential energy is stored in the spring.
  2. The elastic potential energy stored can be calculated using the equation:
  3. elastic potential energy = 0.5 × spring constant × (extension) 2

What is the equation for elastic potential energy GCSE?

Ee = ½ × k × e2 Where: Ee = elastic potential energy in Joules (J) k = spring constant in Newtons per metre (N/m) e = extension in metres (m)

What is K in elastic potential energy formula?

k is the spring constant. It is a proportionality constant that describes the relationship between the strain (deformation) in the spring and the force that causes it.

What is elastic potential energy derive an expression for it?

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 equation of potential energy?

= mgh
Simplified, this formula can be written as: Potential Energy = mgh, where m is the mass, measured in kilograms; g is the acceleration due to gravity (9.8 m/s^2 at the surface of the Earth); and h is the height, measured in meters.

What is the spring potential energy formula?


Equation Symbols Meaning in words
U s = 1 2 k x 2 U_s = \dfrac{1}{2}k x ^2 Us=21kx2 U s U_s Us​U, start subscript, s, end subscript is the elastic potential energy Elastic potential energy is directly proportional to the square of the change in length and the spring constant.

How do you find spring PE?

How to calculate the potential energy of a spring

  1. Determine the spring constant k .
  2. Decide how far you want to stretch or compress your spring.
  3. Substitute these values to the spring potential energy formula: U = ½kΔx2 .
  4. Calculate the energy.

What is EP MGH?

is gravitational potential energy. Explanation: The energy that an object possesses because of its position in a gravitational field is called gravitational potential energy.
