Use momentum conservation to determine the unknowns you will need in order to find the spring constant of the spring that caused the cars to separate. b. The law, while very useful in many elastic materials, called linear elastic or Hookean materials, doesnt apply to every situation and is technically an approximation. Dummies has always stood for taking on complex concepts and making them easy to understand. The formula for finding the spring constant, K, is: F=m (Kx+x) where F is the force exerted by the spring, m is the mass, K is the spring constant and x is the displacement of the spring. He has authored Dummies titles including Physics For Dummies and Physics Essentials For Dummies. Dr. Holzner received his PhD at Cornell.
Dr. Steven Holzner has written more than 40 books about physics and programming. The spring constant is the force needed to stretch or compress a spring, divided by the distance that the spring gets longer or shorter. For example, if you cut a spring in half, its spring constant will double. The minus sign shows that this force is in the opposite direction of the force thats stretching or compressing the spring. X You find the spring constant by suspending weights from the spring, recording the extensions and plotting a graph. You know that the force due to the weight of the car is given by F = mg, where g = 9.81 m/s2, the acceleration due to gravity on Earth, so you can adjust the Hookes law formula as follows: However, only one quarter of the total mass of the car is resting on any wheel, so the mass per spring is 1800 kg / 4 = 450 kg. Mechanical. If you push the spring, however, it pushes back, and if you pull the spring, it pulls back.\r\n
Hookes law is valid as long as the elastic material youre dealing with stays elastic that is, it stays within its . If you pull a spring too far, it loses its stretchy ability. When a force is applied to the combined spring, the same force is applied to each individual spring. \"https://sb\" : \"http://b\") + \".scorecardresearch.com/beacon.js\";el.parentNode.insertBefore(s, el);})();\r\n","enabled":true},{"pages":["all"],"location":"footer","script":"\r\n

Spring-Mass Potential Energy. There are two forces acting at the point where the mass is attached to the spring. k is the spring constant (in N/m); and You can see that if the spring isnt stretched or compressed, it exerts no force on the ball. They inform you that the car will have a mass of 1,000 kilograms, and you have four shock absorbers, each 0.5 meters long, to work with. The formula to find the spring constant is, If you're given a line that represents a spring that obeys Hooke's Law (also called an. So, in my case its cm vs grams. Assuming these shock absorbers use springs, each one has to support a mass of at least 250 kilograms, which weighs the following:\r\n\r\nF = mg = (250 kg)(9.8 m/s2) = 2,450 N\r\n\r\nwhere F equals force, m equals the mass of the object, and g equals the acceleration due to gravity, 9.8 meters per second2. A mass on a spring has a single resonant frequency determined by its spring constant k and the mass m. Using Hooke's law and neglecting damping and the mass of. Hooke's law deals with springs and their main property - the elasticity. What does this mean the spring constant should be? K = - F s F s Or K = F F . which of the following. If you think about what this means in terms of units, or inspect the Hookes law formula, you can see that the spring constant has units of force over distance, so in SI units, newtons/meter.
