What is the equation in solving for momentum?
That would probably depend on the specific situation; there are several equations that involve momentum. Two important equations are: 1) Conservation of momentum: m2 = m1 (i.e., total momentum after some event, such as an impact, is the same as total momentum before the event) 2) The definition of momentum: p = mv (momentum, which is usually written as "p", is mass times velocity) cw: Impulse (Force X time) is equal to the change in momentum.
When a toy truck collides into a toy car the momentum of is the same before and after the collision?
yes the momentum of it is the same because P initial = P final ALWAYS!
If two objects have the same momentum do their magnitudes necessarily have the same directions?
First of all ... I think you're talking about either the magnitude of the momentum, or the magnitudeof the velocity, not the magnitude of the objects.Now ... you're obviously skating around the subject of vectors here, recognizing that both thevelocity and the momentum are vector quantities.If, as you say, the two objects have " ... the same momentum ... ", then you're saying that theirmomentum vectors are equal. If so, then you'd have to say that yes, since the momentum vectorsare equal, the momentum vectors and the velocity vectors must all have the same direction.But if the two momenta only have equal magnitudes, then they ... and the velocities ... can be inany two directions, not necessarily related.
What are units for circumference of a circle?
The same as the units you started with.
Is the momentum of a large bus greater than less than that of a small car traveling at the same speed?
Momentum is a function of velocity and mass, therefore, assuming a "large" bus has more mass than a "small" car the bus would have more momentum since the velocities are the same.
Are momentum and impulse measured in the same units?
No, momentum is measured in units of kilograms times meters per second (kgm/s), while impulse is measured in units of Newton seconds (Ns). Momentum is a measure of an object's motion, while impulse is a measure of the change in momentum experienced by an object.
Are impulse and momentum the same thing?
No, impulse and momentum are not the same thing. Momentum is the product of an object's mass and velocity, while impulse is the change in momentum of an object when a force is applied over a period of time. Impulse helps change an object's momentum.
Is impulse the same as momentum true or false?
False. Impulse and momentum are related concepts but not the same. Momentum is the product of an object's mass and velocity, while impulse is the change in momentum experienced by an object when a force is applied to it over a period of time.
Different standard units of force and momentum and impulse?
Standard units for force are newtons (N), while momentum is typically measured in kilogram meters per second (kg m/s). Impulse, which is the product of force and time, is also measured in newton seconds (Ns) or kilogram meters per second (kg m/s).
Why is it incorrect to say that impulse equals momentum?
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.
The statement 'Impulse is not the same as momentum' is?
True.
Does a moving object have impluse?
Yes, a moving object has impulse. Impulse is the change in momentum of an object, and it is calculated as the product of the force applied to an object and the time over which the force is applied. When an object is moving and experiences a force over a period of time, its momentum changes, resulting in impulse.
What could be described as impulse equals change in momentum?
The principle of impulse equaling the change in momentum states that the force applied to an object over a period of time is equal to the change in the object's momentum. This relationship is described by the equation FΔt = Δmv, where F is the force, Δt is the time over which the force is applied, Δm is the change in momentum, and v is the object's velocity.
Difference between impulse and momentum?
Impulse is another name for change in momentum.Both momentum and impulse have same unit( Ns or kgm/s) . Impulse is also defined as force acting for a time "t". so, Impulse=F*t
What happens to momentum when an impulse acts on a system?
When an impulse acts on a system, the system's momentum changes. The impulse is equal to the change in momentum of the system. If the impulse is in the same direction as the initial momentum, the system's momentum increases. If the impulse is in the opposite direction, the system's momentum decreases.
What is the formula Impulse x time?
The formula for impulse, which is the change in momentum of an object, is Impulse = force x time. It is not the same as Impulse x time.
What are the units associated with mass x velocity?
Momentum is defined as mass times velocity, and it requires units of mass times units of velocity. The SI unit is kilograms x meters / second. There is no special name for this combination of units. Impulse (force times time) has the same units.
