In such a case, work (W) is equal to the force applied (F) multiplied by displacement (\ \Delta\x). b) Find the work done in stretching the spring 1/2 ft beyond its natural length. In the former kind, the magnitude and direction of the force remain unaltered. Which of the following statements about work done by a spring with some constant k k are correct Select ALL that apply. We will explore this idea in greater detail in Section 4.4. Work done by a force can be divided into work from a constant force and work from a variable force. V plot will give us the work done on or by the gas. The work done by a spring depends on the initial and final displacements of the spring the difference between the springs initial and final displacements the. x plot gave us work done, the area under a P(V) vs. If acceleration due to gravity is 10 m/s2, determine (a) the spring constant (b) work done by spring force on object Known : Mass (m) 1 kg Acceleration due to gravity (g) 10 m/s2 Elongation (x) 2 cm 0. A spring has a block attached to one end and the other end is attached to a wall. ![]() Other than Hookes Law, the equation for the potential. Step 1: Make a list of the given quantities in the problem including the spring constant. ![]() In a special case is when work being done is at constant pressure, work simplifies to: An 1-kg object attached to a spring so it is elongated 2 cm. Spring potential energy is the store energy that drives the restoring force described in Hookes Law. Steps for Calculating the Work Done by a Spring System on an Object. If instead of being compressed, the volume expands, the work done on the fluid will be negative since \(dV\) is positive, since the fluid does positive work on some other physical system or work is being done by the system. The minus sign in front of the integral ensures that when the fluid is being compressed (\(dV\) is negative), work comes out positive, since work is being done on the system. This is the expression for the work done on a fluid when it is compressed from a volume V i to a volume V f.
