m1v1+m2v2 =m1u1+m2u2....i think so...thats what i was trying to find out!!!!
Newton's second law is that the force equals the rate of change of momentum:
F = d/dt (MV) = MdV/dt + VdM/dt.
Usually the second term gets forgotten, leaving F=MdV/dt, or in other words:
force = mass times acceleration.
Momentum is the product of the mass and the velocity of an object. It's SI unit is kgms-1. Correct, but perhaps more easily interpreted as kgm/s.
The formula for angular momentum is L = r x p, where L is the angular momentum, r is the distance vector from the axis of rotation to the point of interest, and p is the linear momentum. This formula describes the rotational motion of an object around a fixed axis.
Assuming the photon is reflected into the same medium it came from (so we can ignore refraction), its momentum differs only directionally, its magnitude stays the same. The directional component of its momentum vector is always pointing in the direction it's propagating. Refraction is the means by which the magnitude component of the vector changes. The change in momentum of photon is nh/lambda.
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
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.
To calculate the change in momentum in a scenario, you can use the formula: Change in momentum final momentum - initial momentum. Momentum is calculated by multiplying an object's mass by its velocity. So, to find the change in momentum, subtract the initial momentum from the final momentum.
To find the change in momentum of an object, you can use the formula: Change in Momentum Final Momentum - Initial Momentum. This involves subtracting the initial momentum of the object from its final momentum to determine how much the momentum has changed.
Impulse is a change in momentum. Refer to the related link below for more information and equations about change in momentum, or impulse.
Impulse is a change in momentum. Refer to the related link below for more information and equations about change in momentum, or impulse.
To determine the change in momentum, you can use the formula: Change in momentum Force x Time. This formula helps calculate how much an object's momentum has changed based on the force applied to it and the time over which the force was applied.
The change in momentum can be calculated using the formula: change in momentum = force x time. In this case, the change in momentum would be equal to 20N x 4s = 80Ns.
The definition of impulse is change in momentum, how is there CHANGE in an instant? Or you are asking the instantaneous MOMENTUM, then it's the mass of the object times its speed. Or you are asking the CHANGE in momentum, impulse, after a specific time. If the average force applied to the mass is given, it's force times change in time. If a change in Force is observed, you have to integrate. If there is NO force applied, then the change in momentum is none.
To find time with momentum and force, you can use the impulse-momentum theorem which states that impulse is equal to the change in momentum. Mathematically, impulse (force multiplied by time) equals the change in momentum (mass multiplied by final velocity minus initial velocity). By rearranging the formula, you can solve for time: time = change in momentum / force.
To find force using momentum and time, you can use the formula: Force Change in momentum / Time. This equation helps calculate the force exerted on an object by measuring the change in momentum over a specific period of time.
To determine velocity from impulse, you can use the formula: Impulse Force x Time Change in Momentum. By knowing the impulse and the mass of the object, you can calculate the change in momentum. Then, by dividing the change in momentum by the mass of the object, you can determine the velocity.
( 3 kg-m/sec2 ) x ( 5 sec ) = 15 kg-m/sec
The rate of change of momentum is given by the formula: force x time = change in momentum. In this case, it would be 4 N x 2 s = 8 kg m/s. So, the rate of change of momentum would be 8 kg m/s.
