The idea is that there is a quantity, "amount of movement", formally the product of mass x velocity, that is conserved. That means that the total momentum doesn't change, even if two objects collide, for example - any momentum lost by one object is gained by the other object.

What is impulse momentum theory?
The impulse-momentum theory states that the change in momentum of an object is directly proportional to the impulse applied to it. In other words, the force applied over a certain period of time will result in a change in momentum for an object. This theory is commonly used in analyzing collisions and interactions between objects.
What is the significance of the energy momentum tensor in the context of theoretical physics?
The energy-momentum tensor is significant in theoretical physics because it describes the distribution of energy and momentum in a physical system. It plays a crucial role in Einstein's theory of general relativity, helping to determine the curvature of spacetime and the gravitational effects of matter and energy. In quantum field theory, the energy-momentum tensor is used to calculate the dynamics of particles and fields. Overall, the energy-momentum tensor is a fundamental concept that helps us understand the behavior of matter and energy in the universe.
What is the derivation of relativistic momentum and how does it differ from classical momentum?
The relativistic momentum is derived from Einstein's theory of special relativity, which takes into account the effects of high speeds and near-light velocities. It differs from classical momentum in that it includes a factor of gamma () to account for the increase in mass as an object approaches the speed of light. This means that as an object's velocity increases, its relativistic momentum also increases, unlike classical momentum which remains constant at all speeds.
What is Impulse momentum?
Impulse momentum theory: when force is applied to a rigid body it changes the momentum of the body. it is calculated with respect to time and also the velocity is calculated.
According to modern atomic theory it is nearly impossible to determine an electrons exact?
According to modern atomic theory, it is nearly impossible to determine an electron's exact position and momentum simultaneously. This is known as the Heisenberg Uncertainty Principle, which states that the more precisely one property is measured, the less precisely the other can be known.

In other words, the force applied over a certain period of time will result in a change in momentum for an object.

What concept of physics are seat belts and airbags designed based on?
they relate to the theory behind Momentum and Impulse
Does conservation of angular momentum disprove the big bang?
No, This assumes that the universe is a closed system, while this seems a reasonable hypothesis, the modern big bang theory actually states outright that the universe is not a closed system. Conservation of energy is also violated in the current model, the total energy of the universe is increasing.

What has the author M E Rose written?

What does impulse equal according to the impulse momentum theory?
According to the impulse-momentum theory, impulse equals the change in momentum of an object. Mathematically, impulse is defined as the product of the average force applied to an object and the time duration over which the force is applied. This relationship can be expressed as ( \text{Impulse} = F_{\text{avg}} \Delta t = \Delta p ), where ( \Delta p ) is the change in momentum. Thus, impulse serves as a means to quantify the effect of a force acting over time on an object's motion.
Is momentum conserved in a perfectly inelastic collision?
In any physical process, momentum will always be conserved. Momentum is given by p = m*v. There is also something called law of conservation of momentum.
How do you calculate the new velocity so that momentum remains same?
apply conservation of momentum theory- m1v1=m2v2 where m1 is the initial mass, m2 is the final mass, v1 is the initial velocity and v2 is the final velocity.
What is Impulse momentum?
Impulse momentum theory: when force is applied to a rigid body it changes the momentum of the body. it is calculated with respect to time and also the velocity is calculated.
What is the konopinski-uhlenbeck theory?
An alternate theory of Beta decay, proposed by George Uhlenbeck and Emil Konopinski when it appeared in the mid 1930s that Enrico Fermi's original theory did not give the correct energy spectrum. It is a modification of Fermi's original theory in which the interaction term contains an additional factor of momentum.
