![]() If I weigh 100 Kg and that weight is the product of my mass times gravity, then I have a mass of 10.2 Kg and with the help of gravity, I exert a force of 10.2Kg x 9.8 m/sec2 =10.2*9.8 Kg A Newton (N) is the force exerted by gravity on an object with mass (m). Kinetic energy is measured in Joules – the work expended by applying a force of 1 Newton (or 1 Kg Hold that thought…Į k=1/2mv 2 is a simple formula for kinetic energy. Timing is everything – if I can stop my falling body over a less sudden time span of a few seconds, then the stop at the end becomes less critical and certainly less messy. It’s not the fall that matters, but the sudden stop at the end. What’s more important is not so much that an object changes direction or that it stops, but rather how quickly it does so. However, if the direction of motion is not vertical, then we may not fully consider dynamic loads appropriately, mainly because gravity is less intuitive when motion isn’t vertical or down. We tend to think of dynamic loads in terms of a falling object, because it’s relatively easy to relate acceleration “a”, in F=ma, as the force of gravity. ![]() These are basic precepts of other formulas, which calculate kinetic energy, force of impact and energy dissipation. On the other hand, if an object is not accelerating (either at rest or at a constant velocity) then it has no force acting upon it. Simplified, if an object is accelerating, then it has a force applied to it. When an object accelerates or decelerates, its change in velocity over time is important, but F=ma considers only the instantaneous force of an object’s inertial mass relative to its time rate of change, when accelerating at a fixed rate. The acceleration component to this equation implies that time is a related factor indeed acceleration is the time rate of change in velocity. One of the most basic equations in physics is F=ma. Force is equal to mass times acceleration. In this equation, any change in values for mass or acceleration effects a proportional change in force. Shock loads, impact loads and vibrational loads can all be considered dynamic in nature, but are not the same. Newton’s Laws of Motion reconcile the equilibrium in static systems easily.įor the purposes of this article, you should consider that the term “dynamic load” refers to any load in motion, changing velocity or direction. Loads in a static system are constant and unchanging. Here is how the Dynamic Load Capacity for Bearing given Rated Bearing Life calculation can be explained with given input values -> 38524.9 = 7350*(144^(1/3)).In simple terms, a dynamic load is any load that moves, changing magnitude or direction over time.
