What is an impulse in scientific terms?
Impulse is force x time where the assumption is that the force is high and the time is short. Since force is rate of change of momentum of a free body, then impulse amounts to a sudden change of its momentum.
How do forces cause a change in an object's momentum?
A force acting on a body causes acceleration. Acceleration is measure of the rate of change in the object's velocity. As its velocity changes, its momentum, which is the product of its mass and velocity, will change.
What is impulse in physics?
Einstiens law of relativity. That does not relate to impulse. Impulse equates to a change of momentum, usually thought of as for a very short time, but doesn't have really to be so short. Now since force = mass times acceleration =m.dv/dt, you can write that as d/dt of mv, so force =rate of change of momentum So force times time (or its integral over time, which is the same thing) must equal simply the change of momentum. In the case where it a very short time, all that happens is that the momentum changes instantaneously.
What is the relationship between velocity and inertia?
Newtons First Law of Motion states that an object with a given momentum will continue to posses that same momentum until the object is acted on by a force in which case it will undergo a change in momentum. Inertia is a measure of an objects tendency to resist a change in momentum. Massive bodies have a large inertia. If a massive body is in motion its momentum is given by the product of the mass and the velocity of that body. Newtons first law says that if a force acts on this body its momentum will change. But since the body has a large inertia this change is small. For example, if a small space pebble collides with a large asteroid that has a constant velocity and thus constant momentum, the force is small relative to the inertia of the asteroid so the momentum only changes a little bit.
What is Impulse momentum?
Impulse momentum theory: when force is applied to a rigid body it changes the momentum of the body. it is calculated with respect to time and also the velocity is calculated.
How can you relate a force with the change of a momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
How can you relate a force with the change of momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
How can you relate the force with the change of momentum of a body?
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.
How can you related of force with the change of momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
What is an impulse in scientific terms?
Impulse is force x time where the assumption is that the force is high and the time is short. Since force is rate of change of momentum of a free body, then impulse amounts to a sudden change of its momentum.
What is a direction of impulse?
impulse is equal to force which is acting on the body and ti me in small interval which is equal to momentum.so impulse is equal to change in momentum and direction of impulse is consider the direction of force and change in momentum.
What happens to the momentum of a body acted on by an external force?
If the force opposes the motion, it will reduce the velocity and the momentum of the body will decrease. If the force is in the direction of the motion, the velocity will increase and the momentum will increase.
Initial momentum of a body is 200kgms and it changes to 500kgms in seconds on application of force find the change in momentum and rate of momentum and force applied?
Darn ! I was reading this and really getting into it and planning to tackle it. But you left out how many seconds ??? The change in the body's momentum is +300 kg-m/s . Tell us how many seconds, and we'll answer your other questions too.
What is an air bag in car how it saves driver from injury?
Impulse gives the impact on the body. Impulse is measured by the change in momentum. And rate of change of momentum is force which causes harm on the body. So as we extend the time duration for any change in momentum force is terribly reduced and hence no severe impact. Hence safe journey with a air bag behind the driver.
How do forces cause a change in an object's momentum?
A force acting on a body causes acceleration. Acceleration is measure of the rate of change in the object's velocity. As its velocity changes, its momentum, which is the product of its mass and velocity, will change.

Distinguish between impulse and momentum which is force x time and which is inertia in motion?
Impulse is equal to the change in momentum: definition of impulse is Force x time. When a force is applied to an object for a certain amount of time its momentum (mv) will increase because it is accelerating due to the force on it. Force x time = the change in MV (change in momentum) This is just a restatement of Newtons law F=MA it is actually derived directly from F=MA
