A spring and block are In the arrangement of the flgure below. When the block Is pulled out to x = +3.0 cm, we must apply a force of magnitude 350 N to hold it there, We pull the block to x = +12.5 cm and then release it. Block attached x= 0 F = 0 to spring (a) x positive F, negative (b) x negative F, positive (c) Figure (a): A spring in its relaxed state. The origin of an x axis has been placed at the end of the spring that is attached to a block. Figure (b): The block Is displaced by d, and the spring Is stretched by a positive amount x. Note the restoring force Fs exerted by the spring. Figure (c): The spring is compressed by a negative amount x. Again, note the restoring force. For each of the following, find how much work the spring does on the block when the block moves from the first point given to the second point given the following. (a) X = 6.0 cm to x = 4.5 cm (b) X = 6.0 cm to x = -4.5 cm (c) Xị = 6.0 cm to x = -6.0 cm (d) X = 6.0 cm to x = -12.5 cm 7:54 PM of 67°F 3/15/2022 P Type here to search

Spring Potential Energy

The potential energy is the energy possessed by a body by virtue of its position or the energy held by the object due to its position relative to other objects, its force like stresses, charge, and other factors affecting the particles of the body. The potential energy is the measure of the net work done by or on the body. The spring potential energy is the potential energy stored due to the deformation of an elastic spring and this elasticity is due to the stretched spring. The elasticity is the ability of a solid-state matter to come back to its equilibrium position or original position after any kind of external force is acted on it. It is also known as Elastic potential energy. The potential energy here is caused due to the displacement of the spring from its equilibrium position to another position and this potential energy is equal to the net work done due to the stretching of the spring. It also resembles the same mechanics of the oscillation of a simple pendulum, where due to the external force, the object moves from its equilibrium position to its maximum ends and the periodic motion continues till it comes back to the equilibrium position to rest.
