relation between delta and mass and velocity
Answers
Momentum is a vector quantity that is equal to the mass of an object multiplied by it’s velocity. Momentum is an extremely important quantity in describing motion because it is ‘Conserved’. The total momentum of any system will stay exactly the same forever unless some outside (external) force acts on it.
Consider a single isolated object floating through space with some amount of momentum p.
Newton’s Second Law of Motion tells us that a force, F, acting on this object will cause the momentum to change (in magnitude or in direction).
Mathematically this is written as
F = (delta p)/ (delta t), with delta representing ‘change in’.
For many interactions it is convenient to say that the force F is constant as it acts over the length of time (delta t). Then we can say that the change in momentum (delta p) is equal to F(delta t). This called the ‘Impulse Approximation’ and defines Impulse to be F time t for the interaction.
P=m∆v
Relation between m&∆v is they are inversely proportional to each other
