Click hereto get an answer to your question Derive an expression for the potential energy of an elastic stretched spring. Hot Network Questions What is special about GNU/Linux 3.2.0? As per the law of conservation of energy, since the work done on the object is equal to mgh, the energy gained by the object = mgh, which in this case is the potential energy E.. E of an object raised to a height h above the ground = mgh. The integral form of this relationship is. So, let me calculate the work done by this force. Answer (1 of 14): Sean, since the potential energy stored in a spring is just the work required to compress or extend it, the real question is how do you calculate the work to compress or extend a spring. Potential energy is often associated with restoring forces such as a spring or the force of gravity. Establish an expression for electric energy of a capacitor of capacity c charged to potential v. VN needs policies to promote clean energy. Hot Network Questions What is special about GNU/Linux 3.2.0? -Physics Cbse class 11 Obtain the expression for potential energy of a spring. : Write an expression for potential energy based on m, h, and g.Test your expression using the Gizmo. Expression for potential energy: a. Asked by | 18th Dec, 2009, 12:50: PM. 2.4 K+. Since electrostatic fields are conservative, the work done is path-independent. 557953000. The general expression for gravitational potential energy arises from the law of gravity and is equal to the work done against gravity to bring a mass to a given point in space. Potential Energy Function. W = 0 U . Apply: What is the potential energy of a pendulum with a mass of 0.7 kg, a height of 0.3 m, and a value of g equal to 9.8 m/s 2 Check your answer using the Gizmo. Expert Answer: Hooke's Law, F = -kx, where F is the force and x is the elongation. Consider an object of mass being lifted through a height against the force of gravity as shown below. Since, work W is obtained, i.e. 562113797. hence show that total energy remains conserved in S.H.M. 3. substitute r o back into the original equation. d^2). 5. The coefficients c i (i = 1, . If a body is taken from the surface of the earth to a point at a height h above the surface of the earth, then r i = R and r f = R + h then, U = GMm [1/R 1/(R+h)] U = GMmh/R(R + h) When, h< Obtain the expression for total energy of a system two Back into the original equation change in mass, m, oscillating on a spring with spring Me calculate the work done, W = mgh to move from a point with coordinates ( 3,3,!
