What is the maximum potential energy of a spring?

Hint The potential energy of a spring is associated with its tendency to return to its original position. It will have maximum potential energy when it is the farthest from its original position.

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.

What is the formula for potential energy of a spring?

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).

What does maximum potential energy mean?

Since kinetic energy can never be negative, there is a maximum potential energy and a maximum height, which an object with the given total energy cannot exceed: K=E−U≥0,U≤E.

How do you find the maximum kinetic energy of emitted electrons?

The maximum kinetic energy KEe of ejected electrons (photoelectrons) is given by KEe = hf − BE, where hf is the photon energy and BE is the binding energy (or work function) of the electron to the particular material.

Is Max potential energy equal to max kinetic energy?

At an object’s maximum height, kinetic energy is zero/ maximum while the potential energy is zero/ maximum. At an object’s lowest point, kinetic energy is zero/ maximum while potential energy is zero / maximum. 4.

When the potential energy of a spring is minimum?

When a spring is at its natural length (i.e. neither stretched nor compressed), the potential energy of a spring will be minimum.

How do you find the minimum potential energy?

Π = U + V. For an elastic solid in equilibrium, the expression U = W is a statement of the principle of real work: the work of external forces on an elastic solid is completely stored as strain energy within the solid. The expression δΠ = 0 is a statement of the principle of minimum total potential energy.

How do you find the maximum kinetic energy of a spring?

From calculus, the formula is (0.5)kx^2, where x^2 is the square of the initial displacement of the end of the spring. The kinetic and potential energy at any point will sum to this value. Identify the spring’s maximum kinetic energy, at the equilibrium point, as equal to the initial potential energy.
