![]() Momentum, by definition, involves a body in motion, and can be defined as the tendency of a body in motion to continue moving at a constant velocity. ![]() Inertia, as defined by the second law of motion, is the tendency of an object in motion to remain in motion, and of an object at rest to remain at rest. It might be tempting to confuse momentum with another physical concept, inertia. If a presidential candidate sees a gain in public- opinion polls, then wins a debate and embarks on a whirlwind speaking tour, the media comments that he has "gained momentum." As with momentum in the framework of physics, what these commentators mean is that the candidate will be hard to stop -or to carry the analogy further, that he is doing enough of the right things (thus gaining "mass"), and doing them quickly enough, thereby gaining velocity. In terms of formula, momentum is equal to the product of mass and velocity, and the greater the value of that product, the greater the momentum.Ĭonsider the term "momentum" outside the world of physics, as applied, for example, in the realm of politics. The common meaning of momentum, however, unlike many other physics terms, is relatively consistent with its scientific meaning. Like many other aspects of physics, the word "momentum" is a part of everyday life. Impulse, also defined as a change in momentum, is reflected in the proper methods for hitting a baseball with force or surviving a car crash. A third important concept is impulse, the product of force multiplied by length in time. Like other aspects of matter and motion, momentum is conserved, meaning that when the vector sum of outside forces equals zero, no net linear momentum within a system is ever lost or gained. This is a reflection of momentum, or specifically, linear momentum, which is equal to mass multiplied by velocity. Just basically seeing how things are put together and how and how they work I think is massively important to a lot of people there's only so much you can learn from watching, getting in is really key.The faster an object is moving -whether it be a baseball, an automobile, or a particle of matter -the harder it is to stop. I see a lot of potential for the change that's needed in the food system globally to happen in the in the farming systems and I'd like to be a part of that. That's a real strength that we have at the University particularly within this degree students are able to connect with these key farmers and learn core skills that are going to be valuable to them on their farming enterprises and also in achieving the jobs that they want to get in the future. And I think we've just been lucky to be exposed to some really innovative farmers. I think quite often a lot of people come to this we're coming from maybe a quite an environmental perspective all that sort of thing and they're quite simplistic models about how things function and maybe solutions seem quite simple to us but in reality they're a lot more complex and it's nice to be able to understand that complexity. ![]() Just being able to get out there and speak to farmers directly and hear their problems to hear the complexity of the issues that are in that sort of thing. So I was particularly interested in embracing low-energy means of farming and you know figuring out how to feed people without damaging the earth at the same time. So the regenerative agriculture courses here at Southern Cross University are aimed at students who are interested in pursuing a career in this field and many are already working as practitioners and in some capacity as farmers or in industries that are connected with food – agriculture, broad acre, livestock, production systems. This morning with the custard apple farm like just learning how he integrates both like conventional practices with best practice and regenerative things like it was really inspiring. So looking at farming systems, working out what's working well and what's not and there really is no substitute for these students to be able to actually get out there, meet their peers, meet people in the industry and key researchers here at the University.īeing able to put names to faces and like ask questions in person with our lecturer is especially good. ![]() As a part of the unit we have on-farm residentials and field-based studies that are part of the regenerative agriculture courses here at Southern Cross University and part of that is meeting with farmers and practitioners in their fields so students get to see firsthand these practices and principles of regenerative agriculture and best farming practices.
