Elastic potential energy is the energy stored in an elastic object when it is stretched or compressed. The formula is U = ½kx², where k is the spring constant in newtons per meter (N/m) and x is the displacement from equilibrium in meters (m). This is also known as Hooke's Law energy.
Elastic potential energy is the energy stored in elastic materials when they are stretched or compressed. It is the potential energy of an object due a its deformation, such as a stretched spring or a compressed rubber band.
Spring constant can be entered in newtons per meter (N/m), newtons per centimeter (N/cm), or pounds per inch (lb/in). Displacement can be entered in meters (m), centimeters (cm), millimeters (mm), inches (in), or feet (ft).
The spring constant (k) is a measure of a spring's stiffness. A higher k value means a stiffer spring that requires more force to stretch or compress. It is measured in N/m (newtons per meter).
Yes! Since displacement is squared in the formula (x²), the result is the same whether the spring is compressed or extended by the same amount.
