momentum makes the player harder to slow down and stop, so the player will be able to gain more yards when running with the ball and also help them break tackles. the faster the player is running the more momentum he is carrying. You may hear the term "momentum took him over the line" this means that he has not forced himself over the line through double movement, the momentum he was carrying carried him over.
momentum and swimming are related because you need momentum to keep you going
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
Science: Momentum. Maths: Angles.
It relates to work in the sense that work involves moving things, which involves changing their momentum, and to change momentum you have to create an equal and opposite momentum so that momentum is conserved - although the planet Earth is such a convenient momentum sink that in most cases this happens without being specifically noticed.
they relate to the theory behind Momentum and Impulse
Newton's Second Law was originally formulated as: F=dm/dt. That is, the force is proportional (or equal, if the correct units are used) to the rate of change of momentum. The more force, the faster will the momentum change.
the momentum needed to get all the way around is related to physics.
Unless acted on by an outside force, a body at motion stays at motion. In rugby, unless you stop the person with the ball, they will stay at motion (at least until they score a try).
It isn't closely related. Newton's Third Law is more closely related to conservation of MOMENTUM.
If a rocket is at rest (zero momentum) in outer space, where there is no gravity, then as long as there are no Outside forces on it its momentum must always be zero (consevation of momentum). This must be true even if an internal explosion brakes it into pieces. The pieces must fly off in such a way that their net vector momentum is zero. Turning on the engine is like an internal explosion. The hot gasses, which have mass, are ejected out the back at high velocity so the gas has momentum. In order to keep the total momentum zero the rocket must move forward so its momentum just equals the backward momentum of the gasses and the net momentum of both is zero. The same is almost true when taking off from earth. Because of the Earth's gravity(outside force) the upward momentum of the rocket won't quite equal the downward momentum of the gasses but its almost the same.
Thy operate on the same principle. The water going backwards has momentum that is balanced by the rocket going forward.
