Known weights would then be added to and taken away from the pan on the other side of the fulcrum until the lever was perfectly balanced in a horizontal position. The smaller balances measure newtons and they are equipped with a spring that is less firm. Spring balance is used to measure the weight of the object. A visitor has shared a Gizmo from ExploreLearning.com with you! The variables of the equation are: F which represents force, k which is called the spring constant and measures how stiff and strong the spring is, and x is the distance the spring is stretched or compressed away from its equilibrium or rest position. If you pull a spring too far, it loses its stretchy ability. For example, since the gravity of the moon is about one sixth that of Earth, a 120-pound person on Earth would weigh about 20 pounds on the moon. Hooke's law is a law of physics that states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring.

(more) del Estudiante: Peso y Masa. ; Measuring the mass of a sample on an analytical balance may produce different values as air currents affect the balance or as water enters and leaves the specimen. Any physicist knows that if an object applies a force to a spring, then the spring applies an equal and opposite force to the object. Log in. Since a spring will naturally slacken after repeated stretching, the scale needs to be replaced after a while, since a slackened spring will give erroneous results. It is also possible to use Hooke’s law to convert this scale from measuring spring extension, to a scale which directly measures spring force. If a spring is compressed, then a force with magnitude proportional to the decrease in length from the equilibrium length is pushing each end away from the other. When taking a volume reading in a flask, you may read the value from a different angle each time. 10,410,534, 110 Avon Street, Charlottesville, VA 22902, USA, All other Gizmos are limited to a 5 Minute Preview Note that in this equation m is the total mass attached to the spring.

In order to figure out how to calculate the spring constant, we must remember what Hooke’s law says: Now, we need to rework the equation so that we are calculating for the missing metric which is the spring constant, or k. Looking only at the magnitudes and therefore omitting the negative sign, you get, The springs used in the shock absorbers must have spring constants of at least 4,900 newtons per meter. The car designers rush out, ecstatic, but you call after them, “Don’t forget, you need to at least double that if you actually want your car to be able to handle potholes.”. For example, if the spring scale reading varies between 0.070 N and 0.13 N during the pull, then you would report the experimental value of the force as F = 0.10 N ± 0.03 N. If your pull is steadier, then the uncertainty in the force will be smaller. The deformation can be measured using a spring stays within its elastic limit and Hooke.
