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.
What else can I help you with?
Why is it incorrect to say that impluse equals momentum?
Impulse is a measure of the change in momentum, not its equivalence. Momentum is the product of an object's mass and velocity, while impulse is the product of force and time over which the force acts. So, they are related but not equal.
It is correct to say that impulse is equal to?
Impulse is equal to the change in momentum of an object. Mathematically, impulse (J) is equal to the force (F) applied to an object multiplied by the time (t) over which the force is applied, which can be expressed as J = F * t.
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.
If the velocity is constant does that mean that there is no impulse?
Not necessarily. Impulse Fdt=change in momentum which could be written as mdv (constant mass, velocity changing) or dmv (changing mass, constant velocity - the so-called conveyor belt problem. Imagine a hopper filled with (say) coal is feeding the coal on to a conveyor belt. The mass of the belt increases with time, so a force has to be applied to it to keep it moving at constant velocity.
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
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"
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.
One railroad car rolls toward another Describe the properties of the first car that determine its momentum and how it would impart an impulse to the second car?
(newtons first law) conservation of momentum law states : momentum before collision = momentum after collision momentum p (kg-m/s)= mass * velocity say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s momentum after collision = 10 000 kg-m/s mass now = 1 000 kg+2 000 kg = 3 000 kg 10 000 = 3 000 kg* velocity m/s 10 000/3 000 = velocity 3.33 m/s = velocity after collision an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
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 incorrect grammar to say these ones?
No, it is not incorrect. You could say, "These ones are the best for baking."
