# What is the difference between toeque and momentum?

Torque is **vector energy** e.g FxD and momentum is
the product of mass and speed p= mv or **velocity
P=mV**. Torque is a vector energy and Momentum is energy per
unit speed, a vector or a scalar, W/c = Momentum.

### Why is a neutrino released during positron emission?

To preserve the conservation of; energy, momentum, and angular momentum in beta plus decay. Without the neutrino there is a measurable difference between the energy, momentum, and angular momentum of the initial and final particle. The neutrino rectifies this difference and it's existence was actually postulated before it was ever discovered!

### What is the difference between zero momentum and momentum bias spacecraft?

When the spacecraft is an equilibrium state, if the spacecraft has a momentum for specific axis, then the control of spacecraft is designed to momentum bias method. if else, it is called a zero momentum spacecraft. Zero momentum spacecraft: a spacecraft has four reaction wheel which is installed to pyramid configuration. if1st and 3rd reaction wheel is running to a 500 rpm and 2nd and 4th reaction wheel is running to a 500 rpm, them…

### What is the difference between velocity and momontum?

Well, picture this: A canoe moving east through the water at 3 miles per hour hits the pier, and bounces off of it. About an hour later, a battleship moving east through the water at 3 miles per hour hits the pier, keeps right on going, and demolishes the entire pier. What's the difference ? Both craft had the same velocity ... 3 miles per hour eastward. But each one had different momentum. The difference…

### Why is the law of conservation of momentum useful in analyzing the collision between two bodies?

The law of conservation of momentum useful in analyzing the collision between two bodies because there is use to be the collision between the two bodies reason for that is law of conservation of momentum is that the total sum of momentum is equal means constant after the total sum of momentum of two bodies. so if you don't be the collision between two bodies you will not aware of the meaning of momentum.

### What is the difference between impulse and change in momentum?

An impulse applied to a body will change the original momentum of the body. Impulse is force acting for a very short time, as in a collision. If the force is constant the impulse is I = Fδt. If it is a variable force the impulse is the integral of this over the short time period, I = ⌠Fdt. An impulse is equal to the change of momentum that it produces. The linear momentum P…

### Difference between change in momentum and impulse?

Impulse is equal to the change in momentum: definition of impulse is Force x time. When a force is applied to an object for a certain amount of time its momentum (mv) will increase because it is accelerating due to the force on it. Force x time = the change in MV (change in momentum) This is just a restatement of Newtons law F=MA it is actually derived directly from F=MA

### What is difference between dynamics and mechanics?

Mechanics is the study of the interactions between matter and the forces acting on it. Mechanics is divided into three, namely, statics, dynamics and kinematics. Dynamics is the branch of mechanics concerned with the motion of the bodies under the action of forces. statics - no change of momentum dynamics - change of momentum kinematics - force is not concerned

### What is the difference between momentum and kinetic energy and why is it that kinetic energy can be changed in to other forms of energy but momentum cant?

Firstly, momentum is not a form of energy; the question seems to imply so. Kinetic energy is the energy possessed by a moving object. That energy is provided by a source, and can be removed from the object because energy possessed by an object is not an inherent part of that given object. Momentum is a property of mass; momentum is inherent in the mass of the object, and cannot be removed or put somewhere…

### What is the difference between direct and indirect energy?

The band gap represents the minimum energy difference between the top of the valence band and the bottom of the conduction band, However, the top of the valence band and the bottom of the conduction band are not generally at the same value of the electron momentum. In a direct band gap semiconductor, the top of the valence band and the bottom of the conduction band occur at the same value of momentum. In an…
