Is the impulse-momentum relationship related to newton's second law?
Yes. From Newton's Second Law, you know that to accelerate an object, a net force must be applied to it. The impulse-momentum relationship is basically the same thing, but worded differently. It says that if you wish to change the momentum of an object, you need to exert an impulse on it.From: Conceptual Physics, by Paul Hewitt. 11th Edition, Ch. 6 pg. 89.
Can a moving object have impulse in itself?
yes moving objects have impulse
How do you calculate speed acceleration and momentum?
Acceleration (ms^-2):The definition of acceleration is the change in speed over time.= change in velocity/time= final velocity-initial velocity/timeMomentum (Kg ms^-1):Momentum is defined as the power of a moving object to keep moving. In this example the heavier truck had more power to keep moving, so it caused more damage.Momentum (P) = mass(m) X velocity(v)Speed :In physics, speed is often measured in meters per second. When we travel, we often use miles per hour.Formula: Rate equals distance divided by timeRate = Distance/Time
In order to impart the greatest momentum to an object you should?
In order to impart the greatest momentum to an object, you should both exert the largest force possible upon the object in question and extend that force for as long as possible. This is so because the greater the force acting on an object results in a greater change in velocity, which in turn yields a greater momentum. In addition to exerting the largest force possible on an object, you should also extend that force over the longest period of time as possible, as the sustained force also produces more momentum. As p= m•v, the best method in obtaining the greatest amount for 'p' would be to manipulate either the 'm' or 'v' variables. Force= acceleration= change in velocity= MOMENTUM. Greater amount of time= MOMENTUM
What describes velocity?
two things that describe velocity is distance and time.
What is momentum relaxation time?
Momentum
If the velocity is constant does that mean that the impulse is the momentum?
No, constant velocity means there is no change in velocity over time. Impulse is the change in momentum, given by the force applied over a period of time. Momentum is mass times velocity, a vector quantity.
What do you mean by drift velocity and mobility of a free electron?
Drift velocity Vd = acceleration x relaxation time So Vd = (E e / m) * t Now Vd / E is defined as the drift velocity per unit electric field and known to be mobility of free electron Hence mobility = (e/m) x t Thus mobility will be different in different material as it depends on relaxation time. e/m is the specific charge of electron which is a constant value equals to 1.759 x 1011
How do you find time with momentum and force?
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.
How about if the velocity is doubled but the mass remains the same?
If the velocity is doubled while the mass remains the same, the kinetic energy of the object will increase by a factor of four. This is because kinetic energy is proportional to the square of the velocity. The momentum of the object will also double as momentum is proportional to velocity.
How do you find change in momentum over time given constant velocity?
Momentum = (mass) x (velocity vector).Given constant velocity, and assuming that mass doesn't change,there is no change in momentum over time.If there is any change in momentum, it can only be due to a change in mass.It would change in direct proportion to the mass, and the direction of themomentum vector would remain constant, in the direction of the velocity.
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.
How can one determine velocity from impulse?
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.
What is the momentum of a 200 g object is falling on earth and is timed for 5 seconds?
The momentum of an object can be calculated using the equation p = m * v, where p is momentum, m is mass, and v is velocity. Since the object is falling, its velocity is increasing due to gravity. Without knowing the velocity of the object, we cannot determine its momentum at a specific time. The given time of 5 seconds does not provide enough information to calculate the velocity or momentum of the object.
Why does impulse affect momentum?
Impulse is defined as the change in momentum of an object. When a force is applied to an object over a period of time, it causes a change in the object's velocity, which in turn affects its momentum. Therefore, impulse affects momentum by altering the velocity of an object, leading to a change in its momentum.
How does time affect momentum?
Time does not directly affect momentum. Momentum is determined by an object's mass and velocity, which are independent of time. However, changes in momentum over time can be influenced by forces acting on an object, such as a push or pull, which can accelerate or decelerate the object.
How can it be possible for two objects with different velocities to have the same momentum?
Two objects with different velocities can have the same momentum if one object has a greater mass and a lower velocity while the other object has a lower mass and a greater velocity. Because momentum is the product of mass and velocity, if the product of mass and velocity for each object is the same, their momenta will be equal.
