Impulse is the change in momentum. Therefore Impulse is only equal to momentum if the initial momentum was equal to zero. Its the same phenomenon as position and displacement.
Impulse= final momentum-initial momentum= mv - mv_0= Force * Time
Where m is the mass and v is the velocity.

It is correct to say that impulse is equal to?
A change in impulse equals a change in momentum. However, Impulse is the product of force and time, as is momentum, so they are not exactly the same thing.
What happens to momentum when an impulse acts on a system?
Strictly speaking, you would say that a force acts on a system and the impulse of that force corresponds to the change in momentum of the system due to the action of the force. More mathematically, the impulse of a force is defined as the integral of that force with respect to time over the time period that the force acts.
What does it mean to say momentum is conserved?
What does it mean to say momentum is conserved?
What if your friend says that the law of conservation of momentum violated when a ball rolls down a hill and gain momentum what do you say?
it could be said that since potential energy (mgh) is lost at the exact rate kinetic energy (ke) is gained, that energy is translated into another form since force applied (gravity) over time then impulse applied and increase of momentum
What does the law of conservation of momentum say about the total amount of momentum after a collision?
the total momentum after a collision must be equal the total momentum before the collision.
How do you say to be incorrect in French?
To be incorrect is avoir faute
We say she has or she have?
you cannot say "he have" this is incorrect, it is " he has"
What does it mean to say momentum slowed down?
Momentum is a vector, it is mass times velocity. To say that momentum slows is the same as saying that velocity (speed) drops - it is making something simple sound complicated.
What does it mean to say momentum is directly proportional to mass and velocity?
Being proportional means that if you change one by a given factor, the other will change by that factor as well. Being proprtional to both means it is proportional to their product, i.e. momentum equals mass times velocity, p = mv.
Is it grammatically incorrect to say sister and sister Or just sisters?
It is grammatically incorrect to say sister and sister. You just say sisters.
When the momentum within a system is the same before and after an event you say that what?
You say that momentum is conserved. This is always the case, if the system has no interaction with anything outside the system.
Is it true that an object never loses its momentum?
Momentum is related to velocity and mass. When an object's velocity is zero relative to its surroundings, it has no momentum. Therefore it is untrue to say that an object never looses its momentum.
